Induces Apoptosis

Long dan xie gan tang, a well known Chinese herbal formulation, is commonly used by patients with chronic liver disease in China. Accumulated anecdotal evidence suggests that Long dan tang may have beneficial effects in patients with hepatocellular carcinoma. Long dan tang is comprised of five herbs: Gentiana root, Scutellaria root, Gardenia fruit, Alisma rhizome, and Bupleurum root. The cytotoxic effects of compounds from the five major ingredients isolated from the above plants, i.e. gentiopicroside, baicalein, geniposide, alisol B acetate and saikosaponin-d, respectively, on human hepatoma Hep3B cells, were investigated.

Annexin V immunofluorescence detection, DNA fragmentation assays and FACScan analysis of propidium iodide-staining cells showed that gentiopicroside, baicalein, and geniposide had little effect, whereas alisol B acetate and saikosaponin-d profoundly induced apoptosis in Hep3B cells. Alisol B acetate, but not saikosaponin-d, induced G2/M arrest of the cell-cycle as well as a significant increase in caspase-3 activity. Interestingly, baicalein by itself induced an increase in H(2)O(2) generation and the subsequent NF-kappaB activation; furthermore, it effectively inhibited the transforming growth factor-beta(1) (TGF-beta(1))-induced caspase-3 activation and cell apoptosis.

Results suggest that alisol B acetate and saikosaponin-d induced cell apoptosis through the caspase-3-dependent and -independent pathways, respectively. Instead of inducing apoptosis, baicalein inhibits TGF-beta(1)-induced apoptosis via increase in cellular H(2)O(2) formation and NF-kappaB activation in human hepatoma Hep3B cells (Chou, Pan, Teng & Guh, 2003).

Breast

Saikosaponin-A treatment of MDA-MB-231 for 3 hours and of MCF-7 cells for 2 hours, respectively, caused an obvious increase in the sub G1 population of cell-cycles.

Apoptosis in MDA-MB-231 cells was independent of the p53/p21 pathway mechanism and was accompanied by an increased ratio of Bax to Bcl-2 and c-myc levels and activation of caspase-3. In contrast, apoptosis of MCF-7 cells may have been initiated by the Bcl-2 family of proteins and involved p53/p21 dependent pathway mechanism, and was accompanied by an increased level of c-myc protein. The apoptosis of both MDA-MB-231 and MCF-7 cells showed a difference worthy of further research (Chen, Chang, Chung, & Chen, 2003).

Hepatocellular Carcinoma

The signaling pathway mediating induction of p15(INK4b) and p16(INK4a) during HepG2 growth inhibition triggered by the phorbol ester tumor promoter TPA (12-O-tetradecanoylphorbol 13-acetate) and the Chinese herbal compund Saikosaponin A was investigated.

Expressions of proto-oncogene c-jun, junB and c-fos were induced by TPA and Saikosaponin A between 30 minutes to 6 hours of treatment. Pre-treatment of 20 microg/ml PD98059, an inhibitor of MEK (the upstream kinase of ERK), prevents the TPA and Saikosaponin A triggered HepG2 growth inhibition by 50% and 30%, respectively. In addition, AP-1 DNA-binding assay, using non-isotopic capillary electrophoresis and laser-induced fluorescence (CE/LIF), demonstrated that the AP-1-related DNA-binding activity was significantly induced by TPA and Saikosaponin A, which can be reduced by PD98059 pre-treatment.

Results suggest that activation of ERK, together with its downstream transcriptional machinery, mediated p15(INK4b) and p16(INK4a) expression that led to HepG2 growth inhibition (Wen-Sheng, 2003).

The effects of Saikosaponin D (SSd) on syndecan-2, matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases-2 (TIMP-2) in livers of rats with hepatocellular carcinoma (HCC) was investigated.

The model group had more malignant nodules than the SSd group. Model-group HCC cells were grade III; SSd-group HCC cells were grades I-II. Controls showed normal hepatic cell phenotypes and no syndecan-2+ staining. Syndecan-2+ staining was greater in the model group (35.2%, P < or = 0.001) than in controls or the SSd group (16.5%, P < or = 0.001). The model group had more intense MMP-2+ staining than controls (0.37 vs 0.27, P< or =0.01) or the SSd group (0.31 vs 0.37, P< or =0.05); and higher MMP-13+ staining (72.55%) than in controls (12.55%, P< or =0.001) and SSd group (20.18%, P< or =0.01).

The model group also had more TIMP-2+ staining (57.2%) than controls (20.9%, P< or =0.001) and SSd group (22.7%, P< or=0.001). Controls and SSd group showed no difference in TIMP-2+ rates.

SSd inhibited HCC development, and downregulated expression of syndecan-2, MMP-2, MMP-13 and TIMP-2 in rat HCC liver tissue (Jia et al., 2012).

T Cell-mediated Autoimmune

Saikosaponin-d (Ssd) is a triterpene saponin derived from the medicinal plant, Bupleurum falcatum L. (Umbelliferae). Previous findings showed that Ssd exhibits a variety of pharmacological and immunomodulatory activities including anti-inflammatory, anti-bacterial, anti-viral and anti-cancer effects.

Results demonstrated that Ssd not only suppressed OKT3/CD28-costimulated human T cell proliferation, it also inhibited PMA, PMA/Ionomycin and Con A-induced mouse T cell activation in vitro. The inhibitory effect of Ssd on PMA-induced T cell activation was associated with down-regulation of NF-kappaB signaling through suppression of IKK and Akt activities. In addition, Ssd suppressed both DNA binding activity and the nuclear translocation of NF-AT and activator protein 1 (AP-1) of the PMA/Ionomycin-stimulated T cells. The cell surface markers, such as IL-2 receptor (CD25), were also down-regulated along with decreased production of pro-inflammatory cytokines of IL-6, TNF-alpha and IFN-gamma.

Results indicate that the NF-kappaB, NF-AT and AP-1 (c-Fos) signaling pathways are involved in the T cell inhibition evoked by Ssd. Ssd could be a potential candidate for further study in treating T cell-mediated autoimmune conditions (Wong, Zhou, Cheung, Li, & Liu, 2009).

Cervical Cancer

Saikosaponin-a and -d, two naturally occurring compounds derived from Bupleurum radix, have been shown to exert anti-cancer activity in several cancer cell lines. However, the effect of a combination of saikosaponins with chemotherapeutic drugs have never been addressed. Investigated as to whether these two saikosaponins have chemo-sensitization effect on cisplatin-induced cancer cell cytotoxicity was carried out.

Two cervical cancer cell lines, HeLa and Siha, an ovarian cancer cell line, SKOV3, and a non-small-cell lung cancer cell line, A549, were treated with saikosaponins or cisplatin individually or in combination. Cell death was quantitatively detected by the release of lactate dehydrogenase (LDH) using a cytotoxicity detection kit. Cellular ROS was analyzed by flow cytometry. Apoptosis was evaluated by AO/EB staining, flow cytometry after Anexin V and PI staining, and Western blot for caspase activation. ROS scavengers and caspase inhibitor were used to determine the roles of ROS and apoptosis in the effects of saikosaponins on cisplatin-induced cell death.

Both saikosaponin-a and -d sensitized cancer cells to cisplatin-induced cell death in a dose-dependent manner, which was accompanied with induction of reactive oxygen species (ROS) accumulation.

Results suggest that saikosaponins sensitize cancer cells to cisplatin through ROS-mediated apoptosis, and the combination of saikosaponins with cisplatin could be an effective therapeutic strategy (Wang et al., 2010).

Colon Cancer

Saikosaponin-a (SSa)-induced apoptosis of HCC cells was associated with proteolytic activation of caspase-9, caspase-3, and PARP cleavages and decreased levels of IAP family members, such as XIAP and c-IAP-2, but not of survivin. SSa treatment also enhanced the activities of caspase-2 and caspase-8, Bid cleavage, and the conformational activation of Bax. Moreover, inhibition of caspase-2 activation by the pharmacological inhibitor z-VDVAD-fmk, or by knockdown of protein levels using a si-RNA, suppressed SSa-induced caspase-8 activation, Bid cleavage, and the conformational activation of Bax. Although caspase-8 is an initiator caspase like caspase-2, the inhibition of caspase-8 activation by knockdown using a si-RNA did not suppress SSa-induced caspase-2 activation.

Results suggest that sequential activation of caspase-2 and caspase-8 is a critical step in SSa-induced apoptosis (Kim & Hong, 2011).

Immune Regulating

Tumor necrosis factor-alpha (TNF- α ) was reported as an anti-cancer therapy due to its cytotoxic effect against an array of tumor cells. However, its undesirable responses of TNF- α on activating NF- κB signaling and pro-metastatic property limit its clinical application in treating cancers. Therefore, sensitizing agents capable of overcoming this undesirable effect must be valuable for facilitating the usage of TNF- α -mediated apoptosis therapy for cancer patients. Previously, saikosaponin-d (Ssd), a triterpene saponin derived from the medicinal plant, Bupleurum falcatum L. (Umbelliferae), exhibited a variety of pharmacological activities such as anti-inflammatory, anti-bacterial, anti-viral and anti-cancer.

Investigation found that Ssd could potentially inhibit activated T lymphocytes via suppression of NF- κ B, NF-AT and AP-1 signaling. Ssd significantly potentiated TNF- α -mediated cell death in HeLa and HepG2 cancer cells via suppression of TNF- α -induced NF- κ B activation and its target genes expression involving cancer cell proliferation, invasion, angiogenesis and survival. Also, Ssd revealed a significant potency in abolishing TNF- α -induced cancer cell invasion and angiogenesis in HUVECs while inducing apoptosis via enhancing the loss of mitochondrial membrane potential in HeLa cells.

Collectively, findings indicate that Ssd has significant potential to be developed as a combined adjuvant remedy with TNF- α for cancer patients (Wong et al., 2013).

Radio-sensitizer

Saikosaponin-d (SSd), a monomer terpenoid purified from the Chinese herbal drug Radix bupleuri, has multiple effects, including anti-cancer properties. Treatment with SSd alone and radiation alone inhibited cell growth and increased apoptosis rate at the concentration used. These effects were enhanced when SSd was combined with radiation. Moreover, SSd potentiated the effects of radiation to induce G0/G1 arrest in SMMC-7721 hepatocellular carcinoma cells, and reduced the G2/M-phase population under hypoxia. SSd potentiates the effects of radiation on SMMC-7721 cells; thus, it is a promising radio-sensitizer. The radio-sensitizing effect of SSd may contribute to its effect on the G0/G1 and G2/M checkpoints of the cell-cycle (Wang et al., 2013).

Oxymatrine (Ku Shen)

Cancer:
Sarcoma, pancreatic, breast, liver, lung, oral, colorectal, stomach, gastric, adenoid cystic carcinoma

Action: Anti-angiogenesis, anti-inflammatory, anti-proliferative, chemo-sensitizer, chemotherapy support, cytostatic, radiation support, immunotolerance, induces apoptosis, decreases side-effects of Intensity Modulated Radiation Therapy (IMRT), Transcatheter Hepatic Arterial Chemoembolization (TACE)

Anti-cancer

Oxymatrine, isolated from the dried roots of Sophora flavescens (Aiton), has a long history of use in traditional Chinese medicine to treat inflammatory diseases and cancer. Kushen alkaloids (KS-As) and kushen flavonoids (KS-Fs) are well-characterized components in kushen. KS-As containing oxymatrine, matrine, and total alkaloids have been developed in China as anti-cancer drugs. More potent anti-tumor activities were identified in KS-Fs than in KS-As in vitro and in vivo (Sun et al., 2012).

Angiogenesis

Oxymatrine has been found to inhibit angiogenesis when administered by injection. The tumor-inhibitory rate and the vascular density were tested in animal tumor model with experimental treatment. The expression of VEGF and bFGF were measured by immunistological methods. When high doses were used, the tumor-inhibitory rate of oxymatrine was 31.36%, and the vascular density of S180 sarcoma was lower than that in the control group, and the expression of VEGF and bFGF was down-regulated. Oxymatrine hence has an inhibitory effect on S180 sarcoma and strong inhibitory effects on angiogenesis. Its mechanism may be associated with the down-regulating of VEGF and bFGF expression (Kong et al., 2003).

Immunotolerance

Matrine, a small molecule derived from the root of Sophora flavescens AIT, was demonstrated to be effective in inducing T cell anergy in human Jurkat cells. Induction of immunotolerance has become a new strategy for treating autoimmune conditions in recent decades. However, so far there is no ideal therapeutics available for clinical use. Medicinal herbs are a promising potential source of immunotolerance inducers. Bioactive compounds derived from medicinal plants were screened for inducing T cell anergy in comparison with the effect of well-known T cell anergy inducer, ionomycin.

The results showed that passage of the cells, and concentration and stimulation time of ionomycin on the cells, could influence the ability of T cell anergy induction. The cells exposed to matrine showed markedly decreased mRNA expression of interleukin-2, an indicator of T cell anergy, when the cells were stimulated by antigens, anti-OKT3 plus anti-CD28. Mechanistic study showed that ionomycin and matrine could up-regulate the anergy-associated gene expressions of CD98 and Jumonji and activate nuclear factor of activated T-cells (NFAT) nuclear translocation in absence of cooperation of AP-1 in Jurkat cells. Pre-incubation with matrine or ionomycin could also shorten extracellular signal-regulated kinase (ERK) and suppress c-Jun NH(2)-terminal kinase (JNK) expression on the anergic Jurkat cells when the cells were stimulated with anti-OKT-3 plus anti-CD28 antibodies. Thus, matrine is a strong candidate for further investigation as a T cell immunotolerance inducer (Li et al., 2010).

Induces Apoptosis

The cytotoxic effects of oxymatrine on MNNG/HOS cells were examined by MTT and bromodeoxyuridine (BrdU) incorporation assays. The percentage of apoptotic cells and the level of mitochondrial membrane potential ( Δψ m) were assayed by flow cytometry. The levels of apoptosis-related proteins were measured by Western blot analysis or enzyme assay Kit.

Results showed that treatment with oxymatrine resulted in a significant inhibition of cell proliferation and DNA synthesis in a dose-dependent manner, which has been attributed to apoptosis. Oxymatrine considerably inhibited the expression of Bcl-2 whilst increasing that of Bax.

Oxymatrine significantly suppressed tumor growth in female BALB/C nude mice bearing MNNG/HOS xenograft tumors. In addition, no evidence of drug-related toxicity was identified in the treated animals by comparing the body weight increase and mortality (Zhang et al., 2013).

Pancreatic Cancer

Cell viability assay showed that treatment of PANC-1 pancreatic cancer cells with oxymatrine resulted in cell growth inhibition in a dose- and time-dependent manner. Oxymatrine decreased the expression of angiogenesis-associated factors, including nuclear factor κB (NF-κB) and vascular endothelial growth factor (VEGF). Finally, the anti-proliferative and anti-angiogenic effects of oxymatrine on human pancreatic cancer were further confirmed in pancreatic cancer xenograft tumors in nude mice (Chen et al., 2013).

Induces Apoptosis in Pancreatic Cancer

Oxymatrine inhibited cell viability and induced apoptosis of PANC-1 cells in a time- and dose-dependent manner. This was accompanied by down-regulated expression of Livin and Survivin genes while the Bax/Bcl-2 ratio was up-regulated. Furthermore, oxymatrine treatment led to the release of cytochrome c and activation of caspase-3 proteins. Oxymatrine can induce apoptotic cell death of human pancreatic cancer, which might be attributed to the regulation of Bcl-2 and IAP families, release of mitochondrial cytochrome c, and activation of caspase-3 (Ling et al., 2011).

Decreases Side-effects of Intensity Modulated Radiation Therapy (IMRT)

The levels of sIL-2R and IL-8 in peripheral blood cells of patients with rectal cancer were measured after treatment with the compound matrine, in combination with radiation. Eighty-four patients diagnosed with rectal carcinoma were randomly divided into two groups: therapeutic group and control group.

The patients in the therapeutic group were treated with compound matrine and intensity- modulated radiation therapy (IMRT) (30 Gy/10 f/2 W), while the patients in control group were treated with IMRT. The clinical effects and the levels of IL-8 and sIL-2R tested by ELISA pre-radiation and post-radiation were compared. In addition, 42 healthy people were singled out from the physical examination center in the People's Hospital of Yichun city, which were considered as healthy controls.

The clinical effect and survival rate in the therapeutic group was significantly higher (47.6%) than those in the control group (21.4%). All patients were divided by improvement, stability, and progression of disease in accordance with Karnofsky Performance Scale (KPS). According to the KPS, 16 patients had improvement, 17 stabilized and 9 had disease progress, in the therapeutic group. However, the control group had 12 improvements, 14 stabilized, and 16 progress.

The quality of life in the therapeutic group was higher than tthat in the control group, by rank sum test. SIL-2R and IL-8 examination found that serum levels of sIL-2R and IL-8 were higher in rectal cancer patients before treatments than those in the healthy groups, by student test.

However, sIL-2R and IL-8 serum levels were found significantly lower in the 84 rectal cancer patients after radiotherapy. The level of sIL-2R and IL-8 in the therapeutic group was lower on the first and 14th day, post-radiation, when compared to the control group. However, there was no significant difference on the first day and 14th day, between both experimental groups post- therapy, according to the student test. Side-effects of hepatotoxicity (11.9%) and radiation proctitis (9.52%) were fewer in the therapeutic group.

Compound matrine can decrease the side-effects of IMRT, significantly inhibit sIL-2R and IL-8 in peripheral blood from radiation, and can improve survival quality in patients with rectal cancer (Yin et al., 2013).

Gastric Cancer

The clinical effect of matrine injection, combined with S-1 and cisplatin (SP), in the treatment of advanced gastric cancer was investigated. Seventy-six cases of advanced gastric cancer were randomly divided into either an experimental group or control group. Patients in the two groups were treated with matrine injection combined with SP regimen, or SP regimen alone, respectively.

The effectiveness rate of the experimental group and control group was 57.5% and 52.8% respectively. Therapeutic effect of the two groups of patients did not differ significantly. Occurrence rate of symptom indexes in the treatment group were lower than those of control group, with exception of nausea and vomiting, in which there was no significant difference.

The treatment of advanced gastric cancer with matrine injection, combined with the SP regimen, can significantly improve levels of white blood cells and hemoglobin, liver function, incidence of diarrhea and constipation, and neurotoxicity, to improve the quality of life in patients with advanced gastric cancer (Xia, 2013).

Adenoid Cystic Carcinoma

The effects of compound radix Sophorae flavescentis injection on proliferation, apoptosis and Caspase-3 expression in human adenoid cystic carcinoma ACC-2 cells was investigated.

Compound radix Sophorae flavescentis injection could inhibit the proliferation of ACC-2 cells in vitro, and the dosage effect relationship was significant (P < 0.01). IC50 of ACC-2 was 0.84 g/ml. Flow cytometry indicated that radix Sophorae flavescentis injection could arrest ACC-2 cells at the G0/G1 phase, with a gradual decrease of presence in the G2/M period and S phase. With an increase in dosage, ACC-2 cell apoptosis rate increased significantly (P < 0.05 or P < 0.01).

Radix Sophorae flavescentis injection could enhance ACC-2 cells Caspase-3 protein expression (P < 0.05 or P < 0.01), in a dose-dependent manner. It also could effectively restrain human adenoid cystic carcinoma ACC-2 cells Caspases-3 protein expression, and induce apoptosis, inhibiting tumor cell proliferation (Shi & Hu, 2012).

Breast Cancer Post-operative Chemotherapy

A retrospective analysis of oncological data of 70 post-operative patients with breast cancer from January 2008 to August 2011 was performed. According to the treatment method, the patients were divided into a therapy group (n=35) or control group (n=35). Patients in the control group were treated with the taxotere, adriamycin and cyclophosphamide regimen (TAC). The therapy group was treated with a combination of TAC and sophora root injection. Improved quality of life and incidence of adverse events, before and after treatment, for 2 cycles (21 days to a cycle) were compared.

The objective remission rate of therapy group compared with that of control group was not statistically significant (P > 0.05), while the difference of the disease control rate in two groups was statistically significant (P < 0.05). The improvement rate of total quality of life in the therapy group was higher than that of the control group (P < 0.05). The drop of white blood cells and platelets, gastrointestinal reaction, elevated SGPT, and the incidence of hair loss in the therapy group were lower than those of the control group (P < 0.05).

Sophora root injection combined with chemotherapy in treatment of breast cancer can enhance the effect of chemotherapy, reduce toxicity and side-effects, and improve quality of life (An, An & Wu, 2012).

Lung Cancer Pleural Effusions

The therapeutic efficiency of fufangkushen injection, IL-2, α-IFN on lung cancer accompanied with malignancy pleural effusions, was observed.

One hundred and fifty patients with lung cancer, accompanied with pleural effusions, were randomly divided into treatment and control groups. The treatment group was divided into three groups: injected fufangkushen plus IL-2, fufangkushen plus α-tFN, and IL-2 plus α-IFN, respectively. The control group was divided into three groups and injected fufangkushen, IL-2 and α-IFN, respectively. Therapeutic efficiency and adverse reactions were observed after four weeks.

The effective rate of fufangkushen, IL-2, and α-IFN in a combination was significantly superior to single pharmacotherapy. The effective rate of fufangkushen plus ct-IFN was highest. In adverse reactions, the incidence of fever, chest pains, and the reaction of gastrointestinal tract in the treatment group were significantly less than in the matched group.

The effect of fufangkushen, IL-2, and α-IFN, in a combination, on lung cancer with pleural effusions was significantly better than single pharmacotherapy. Moreover, the effect of fufangknshen plus IL-2 or α-IFN had the greatest effect (Hu & Mei, 2012).

Colorectal Cancer Immunologic Function

The effects of compound Kushen (Radix sophorae flavescentis) injection on the immunologic function of patients after colorectal cancer resection, were studied.

Eighty patients after colorectal cancer resection were randomly divided into two groups: 40 patients in the control group were treated with routine chemotherapy including 5-fluorouridine(5-FU), calcium folinate(CF) and oxaliplatin, and 40 patients in the experimental group were treated with the same chemotherapy regime combined with 20 mL·d-1 compound Kushen injection, for 10 days during chemotherapy.

In the control group the numbers of CD3+,CD4+T cells, NK cells and CD4+/CD8+ ratio significantly declined relative to prior to chemotherapy (P < 0.05), while CD8+T lymphocyte number increased significantly. In the experimental group, there were no significant differences between the numbers of CD3+,CD4+,CD8+T cells, NK cells, and CD4+/CD8+ ratio, before and after chemotherapy (P > 0.05).

After chemotherapy, the numbers of CD3+,CD4+T cells, NK cells and CD4+/CD8+ ratio were higher in the experimental group than in the control group (P0.05), while the number of CD8+T lymphocyte was similar between two groups. Compound Kushen injection can improve the immunologic function of patients receiving chemotherapy after colorectal cancer resection (Chen, Yu, Yuan, & Yuan, 2009).

Stage III and IV non-small-cell lung cancer (NSCLC)

A total of 286 patients with advanced NSCLC were enrolled for study. The patients were treated with either compound Kushen injection in combination with NP (NVB + CBP) chemotherapy (vinorelbine and carboplatin, n = 144), or with NP (NVB + CBP) chemotherapy alone (n = 142). The chemotherapy was performed for 4 cycles of 3 weeks, and the therapeutic efficacy was evaluated every 2 weeks. The following indicators were observed: levels of Hb, WBC, PLT and T cell subpopulations in blood, serum IgG level, short-term efficacy, adverse effects and quality of life.

The gastrointestinal reactions and the myelosuppression in the combination chemotherapy group were alleviated when compared with the chemotherapy alone group, showing a significant difference. (P < 0.05). CD (8)(+) cells were markedly declined in the combination chemotherapy group, and the CD (4)(+)/CD (8)(+) ratio showed an elevation trend in the chemotherapy alone group.

The Karnofsky Performance Scale (KPS) scores and serum IgM and IgG levels were higher in the combination chemotherapy group than those in the chemotherapy alone group (P < 0.01 and P < 0.05). The serum lgA levels were not significantly different in the two groups.

The compound Kushen injection plus NP chemotherapy regimen showed better therapeutic effect, reduced adverse effects of chemotherapy and improved the quality of life in patients with stage III and IV NSCLC (Fan et al., 2010).

Lung Adenocarcinoma

Suppression effects of different concentrations of matrine injection and matrine injection combined with anti-tumor drugs on lung cancer cells were measured by methyl thiazolyl tetrazolium (MTT) colorimetric assay.

Different concentrations of matrine injection could inhibit the growth of SPCA/I human lung adenocarcinoma cells. There was a positive correlation between the inhibition rate and the drug concentration. Different concentrations of matrine injection combined with anti-tumor drugs had a higher growth inhibition rate than anti-tumor drugs alone.

Matrine injection has direct growth suppression effect on SPCA/I human lung adenocarcinoma cells and SS+ injection combined with anti-tumor drugs shows a significant synergistic effect on tumor cells (Zhu, Jiang, Lu, Guo, & Gan, 2008).

Transcatheter Hepatic Arterial Chemoembolization (TACE)

The effect of composite Kushen injection combined with transcatheter hepatic arterial chemoembolization (TACE) on unresectable primary liver cancer, was studied.

Fifty-seven patients with unresectable primary liver cancer were randomly divided into two groups. The treatment group with 27 cases was treated by TACE combined with composite Kushen injection, and the control group with 30 cases was treated by TACE alone. The clinical curative effects were observed after treatment in both groups.

One-, 2-, and 3-year survival rates of the treatment group were 67%, 48%, and 37% respectively, and those of control group were 53%, 37%, and 20% respectively. There were significant differences between both groups (P < 0.05).

Combined TACE with composite Kushen injection can increase the efficacy of patients with unresectable primary liver cancer (Wang & Cheng, 2009).

Nomilin

Cancer: Melanoma, breast cancer

Action: Anti-angiogenic

Nomilin is a triterpenoid present in common edible citrus fruits (Citrus grandis [(L.) Osb.], Citrus unshiu [(Swingle) Marcow.] and Citrus reticulata (Blanco)) with putative anti-cancer properties.

Melanoma

Nomilin possess anti-metastatic action, inducing metastasis in C57BL/6 mice through the lateral tail vein using highly metastatic B16F-10 melanoma cells. Administration of nomilin inhibited tumor nodule formation in the lungs (68%) and markedly increased the survival rate of the metastatic tumor–bearing animals. Nomilin showed an inhibition of tumor cell invasion and activation of matrix metalloproteinases. Treatment with nomilin induced apoptotic response.

Nomilin treatment also exhibited a down-regulated Bcl-2 and cyclin-D1 expression and up-regulated p53, Bax, caspase-9, caspase-3, p21, and p27 gene expression in B16F-10 cells. Pro-inflammatory cytokine production and gene expression were found to be down-regulated in nomilin-treated cells. The study also reveals that nomilin could inhibit the activation and nuclear translocation of anti-apoptotic transcription factors such as nuclear factor (NF)-κB, CREB, and ATF-2 in B16F-10 cells (Pratheeshkumar et al., 2011).

Breast Cancer; ER+

A panel of 9 purified limonoids, including limonin, nomilin, obacunone, limonexic acid (LNA), isolimonexic acid (ILNA), nomilinic acid glucoside (NAG), deacetyl nomilinic acid glucoside (DNAG), limonin glucoside (LG) and obacunone glucoside (OG) as well as 4 modified compounds such as limonin methoxime (LM), limonin oxime (LO), defuran limonin (DL), and defuran nomilin (DN), were screened for their cytotoxicity on estrogen receptor (ER)-positive (MCF-7) or ER-negative (MDA-MB-231) human breast cancer cells. Findings indicated that the citrus limonoids may have potential for the prevention of estrogen-responsive breast cancer (MCF-7) via caspase-7 dependent pathways (Lin et al., 2013).

Blocks Angoigenesis

Nomilin significantly inhibited tumor-directed capillary formation. Serum pro-inflammatory cytokines such as IL-1β, IL-6, TNF-α and GM-CSF and also serum NO levels were significantly reduced by the treatment of nomilin. Administration of nomilin significantly reduced the serum level of VEGF, a pro-angiogenic factor and increased the anti-angiogenic factors IL-2 and TIMP-1. Nomilin significantly retarded endothelial cell proliferation, migration, invasion and tube formation. These data clearly demonstrate the anti-angiogenic potential of nomilin by down-regulating the activation of MMPs, production of VEGF, NO and pro-inflammatory cytokines as well as up-regulating IL-2 and TIMP (Pratheeshkumar et al., 2011).

Betulin and Betulinic acid

Cancer:
Neuroblastoma, medulloblastoma, glioblastoma, colon, lung, oesophageal, leukemia, melanoma, pancreatic, prostate, breast, head & neck, myeloma, nasopharyngeal, cervical, ovarian, esophageal squamous carcinoma

Action: Anti-angiogenic effects, induces apoptosis, anti-oxidant, cytotoxic and immunomodifying activities

Betulin is a naturally occurring pentacyclic triterpene found in many plant species including, among others, in Betula platyphylla (white birch tree), Betula X caerulea [Blanch. (pro sp.)], Betula cordifolia (Regel), Betula papyrifera (Marsh.), Betula populifolia (Marsh.) and Dillenia indica L . It has anti-retroviral., anti-malarial., and anti-inflammatory properties, as well as a more recently discovered potential as an anti-cancer agent, by inhibition of topoisomerase (Chowdhury et al., 2002).

Betulin is found in the bark of several species of plants, principally the white birch (Betula pubescens ) (Tan et al., 2003) from which it gets its name, but also the ber tree (Ziziphus mauritiana ), selfheal (Prunella vulgaris ), the tropical carnivorous plants Triphyophyllum peltatum and Ancistrocladus heyneanus, Diospyros leucomelas , a member of the persimmon family, Tetracera boiviniana , the jambul (Syzygium formosanum ) (Zuco et al., 2002), flowering quince (Chaenomeles sinensis ) (Gao et al., 2003), rosemary (Abe et al., 2002) and Pulsatilla chinensis (Ji et al., 2002).

Anti-cancer, Induces Apoptosis

The in vitro characterization of the anti-cancer activity of betulin in a range of human tumor cell lines (neuroblastoma, rhabdomyosarcoma-medulloblastoma, glioma, thyroid, breast, lung and colon carcinoma, leukaemia and multiple myeloma), and in primary tumor cultures isolated from patients (ovarian carcinoma, cervical carcinoma and glioblastoma multiforme) was carried out to probe its anti-cancer effect. The remarkable anti-proliferative effect of betulin in all tested tumor cell cultures was demonstrated. Furthermore, betulin altered tumor cell morphology, decreased their motility and induced apoptotic cell death. These findings demonstrate the anti-cancer potential of betulin and suggest that it may be applied as an adjunctive measure in cancer treatment (Rzeski, 2009).

Lung Cancer

Betulin has also shown anti-cancer activity on human lung cancer A549 cells by inducing apoptosis and changes in protein expression profiles. Differentially expressed proteins explained the cytotoxicity of betulin against human lung cancer A549 cells, and the proteomic approach was thus shown to be a potential tool for understanding the pharmacological activities of pharmacophores (Pyo, 2009).

Esophageal Squamous Carcinoma

The anti-tumor activity of betulin was investigated in EC109 cells. With the increasing doses of betulin, the inhibition rate of EC109 cell growth was increased, and their morphological characteristics were changed significantly. The inhibition rate showed dose-dependent relation.

Leukemia

Betulin hence showed potent inhibiting effects on EC109 cells growth in vitro (Cai, 2006).

A major compound of the methanolic extract of Dillenia indica L. fruits, betulinic acid, showed significant anti-leukaemic activity in human leukaemic cell lines U937, HL60 and K562 (Kumar, 2009).

Betulinic acid effectively induces apoptosis in neuroectodermal and epithelial tumor cells and exerts little toxicity in animal trials. It has been shown that betulinic acid induced marked apoptosis in 65% of primary pediatric acute leukemia cells and all leukemia cell lines tested. When compared for in vitro efficiency with conventionally used cytotoxic drugs, betulinic acid was more potent than nine out of 10 standard therapeutics and especially efficient in tumor relapse. In isolated mitochondria, betulinic acid induced release of both cytochrome c and Smac. Taken together, these results indicated that betulinic acid potently induces apoptosis in leukemia cells and should be further evaluated as a future drug to treat leukemia (Ehrhardt, 2009).

Multiple Myeloma

The effect of betulinic acid on the induction apoptosis of human multiple myeloma RPMI-8226 cell line was investigated. The results showed that within a certain concentration range (0, 5, 10, 15, 20 microg/ml), IC50 of betulinic acid to RPMI-8226 at 24 hours was 10.156+/-0.659 microg/ml, while the IC50 at 48 hours was 5.434+/-0.212 microg/ml, and its inhibiting effect on proliferation of RPMI-8226 showed both a time-and dose-dependent manner.

It is therefore concluded that betulinic acid can induce apoptosis of RPMI-8226 within a certain range of concentration in a time- and dose-dependent manner. This phenomenon may be related to the transcriptional level increase of caspase 3 gene and decrease of bcl-xl. Betulinic acid also affects G1/S in cell-cycle which arrests cells at phase G0/G1 (Cheng, 2009).

Anti-angiogenic Effects, Colorectal Cancer

Betulinic acid isolated from Syzygium campanulatum Korth (Myrtaceae) was found to have anti-angiogenic effects on rat aortic rings, matrigel tube formation, cell proliferation and migration, and expression of vascular endothelial growth factor (VEGF). The anti-tumor effect was studied using a subcutaneous tumor model of HCT 116 colorectal carcinoma cells established in nude mice. Anti-angiogenesis studies showed potent inhibition of microvessels outgrowth in rat aortic rings, and studies on normal and cancer cells did not show any significant cytotoxic effect.

In vivo anti-angiogenic study showed inhibition of new blood vessels in chicken embryo chorioallantoic membrane (CAM), and in vivo anti-tumor study showed significant inhibition of tumor growth due to reduction of intratumor blood vessels and induction of cell death. Collectively, these results indicate betulinic acid as an anti-angiogenic and anti-tumor candidate (Aisha, 2013).

Nasopharyngeal Carcinoma Melanoma, Leukemia, Lung, Colon, Breast,Prostate, Ovarian Cancer

Betulinic acid is an effective and potential anti-cancer chemical derived from plants. Betulinic acid can kill a broad range of tumor cell lines, but has no effect on untransformed cells. The chemical also kills melanoma, leukemia, lung, colon, breast, prostate and ovarian cancer cells via induction of apoptosis, which depends on caspase activation. However, no reports are yet available about the effects of betulinic acid on nasopharyngeal carcinoma (NPC), a widely spread malignancy in the world, especially in East Asia.

In a study, Liu & Luo (2012) showed that betulinic acid can effectively kill CNE2 cells, a cell line derived from NPC. Betulinic acid-induced CNE2 apoptosis was characterized by typical apoptosis hallmarks: caspase activation, DNA fragmentation, and cytochrome c release.

These observations suggest that betulinic acid may serve as a potent and effective anti-cancer agent in NPC treatment. Further exploration of the mechanism of action of betulinic acid could yield novel breakthroughs in anti-cancer drug discovery.

Cervical Carcinoma

Betulinic acid has shown anti-tumor activity in some cell lines in previous studies. Its anti-tumor effect and possible mechanisms were investigated in cervical carcinoma U14 tumor-bearing mice. The results showed that betulinic acid (100 mg/kg and 200 mg/kg) effectively suppressed tumor growth in vivo. Compared with the control group, betulinic acid significantly improved the levels of IL-2 and TNF-alpha in tumor-bearing mice and increased the number of CD4+ lymphocytes subsets, as well as the ratio of CD4+/CD8+ at a dose of 200 mg/kg.

Furthermore, treatment with betulinic acid induced cell apoptosis in a dose-dependent manner in tumor-bearing mice, and inhibited the expression of Bcl-2 and Ki-67 protein while upregulating the expression of caspase-8 protein. The mechanisms by which BetA exerted anti-tumor effects might involve the induction of tumor cell apoptosis. This process is also related to improvement in the body's immune response (Wang, 2012).

Anti-oxidant, Cytotoxic and Immunomodifying Activities

Betulinic acid exerted cytotoxic activity through dose-dependent impairment of viability and mitochondrial activity of rat insulinoma m5F (RINm5F) cells. Decrease of RINm5F viability was mediated by nitric oxide (NO)-induced apoptosis. Betulinic acid also potentiated NO and TNF-α release from macrophages therefore enhancing their cytocidal action. The rosemary extract developed more pronounced anti-oxidant, cytotoxic and immunomodifying activities, probably due to the presence of betulinic acid (Kontogianni, 2013).

Pancreatic Cancer

Lamin B1 is a novel therapeutic target of Betulinic Acid in pancreatic cancer. The role and regulation of lamin B1 (LMNB1) expression in human pancreatic cancer pathogenesis and betulinic acid-based therapy was investigated. Lamin proteins are thought to be involved in nuclear stability, chromatin structure and gene expression. Elevation of circulating LMNB1 marker in plasma could detect early stages of HCC patients, with 76% sensitivity and 82% specificity. Lamin B1 is a clinically useful biomarker for early stages of HCC in tumor tissues and plasma (Sun, 2010).

It was found that lamin B1 was significantly down-regulated by BA treatment in pancreatic cancer in both in vitro culture and xenograft models. Overexpression of lamin B1 was pronounced in human pancreatic cancer and increased lamin B1 expression was directly associated with low grade differentiation, increased incidence of distant metastasis and poor prognosis of pancreatic cancer patients.

Furthermore, knockdown of lamin B1 significantly attenuated the proliferation, invasion and tumorigenicity of pancreatic cancer cells. Lamin B1 hence plays an important role in pancreatic cancer pathogenesis and is a novel therapeutic target of betulinic acid treatment (Li, 2013).

Multiple Myeloma, Prostate Cancer

The inhibition of the ubiquitin-proteasome system (UPS) of protein degradation is a valid anti-cancer strategy and has led to the approval of bortezomib for the treatment of multiple myeloma. However, the alternative approach of enhancing the degradation of oncoproteins that are frequently overexpressed in cancers is less developed. Betulinic acid (BA) is a plant-derived small molecule that can increase apoptosis specifically in cancer but not in normal cells, making it an attractive anti-cancer agent.

Results in prostate cancer suggest that BA inhibits multiple deubiquitinases (DUBs), which results in the accumulation of poly-ubiquitinated proteins, decreased levels of oncoproteins, and increased apoptotic cell death. In the TRAMP transgenic mouse model of prostate cancer, treatment with BA (10 mg/kg) inhibited primary tumors, increased apoptosis, decreased angiogenesis and proliferation, and lowered androgen receptor and cyclin D1 protein.

BA treatment also inhibited DUB activity and increased ubiquitinated proteins in TRAMP prostate cancer but had no effect on apoptosis or ubiquitination in normal mouse tissues. Overall, this data suggests that BA-mediated inhibition of DUBs and induction of apoptotic cell death specifically in prostate cancer but not in normal cells and tissues may provide an effective non-toxic and clinically selective agent for chemotherapy (Reiner, 2013).

Melanoma

Betulinic acid was recently described as a melanoma-specific inducer of apoptosis, and it was investigated for its comparable efficacy against metastatic tumors and those in which metastatic ability and 92-kD gelatinase activity had been decreased by introduction of a normal chromosome 6. Human metastatic C8161 melanoma cells showed greater DNA fragmentation and growth arrest and earlier loss of viability in response to betulinic acid than their non-metastatic C8161/neo 6.3 counterpart.

These effects involved induction of p53 without activation of p21WAF1 and were synergized by bromodeoxyuridine in metastatic Mel Juso, with no comparable responses in non-metastatic Mel Juso/neo 6 cells. These data suggest that betulinic acid exerts its inhibitory effect partly by increasing p53 without a comparable effect on p21WAF1 (Rieber, 1998).

As a result of bioassay–guided fractionation, betulinic acid has been identified as a melanoma-specific cytotoxic agent. In follow-up studies conducted with athymic mice carrying human melanomas, tumor growth was completely inhibited without toxicity. As judged by a variety of cellular responses, anti-tumor activity was mediated by the induction of apoptosis. Betulinic acid is inexpensive and available in abundant supply from common natural sources, notably the bark of white birch trees. The compound is currently undergoing preclinical development for the treatment or prevention of malignant melanoma (Pisha, 1995).

Betulinic acid strongly and consistently suppressed the growth and colony-forming ability of all human melanoma cell lines investigated. In combination with ionizing radiation the effect of betulinic acid on growth inhibition was additive in colony-forming assays.

Betulinic acid also induced apoptosis in human melanoma cells as demonstrated by Annexin V binding and by the emergence of cells with apoptotic morphology. The growth-inhibitory action of betulinic acid was more pronounced in human melanoma cell lines than in normal human melanocytes.

The properties of betulinic acid make it an interesting candidate, not only as a single agent but also in combination with radiotherapy. It is therefore concluded that the strictly additive mode of growth inhibition in combination with irradiation suggests that the two treatment modalities may function by inducing different cell death pathways or by affecting different target cell populations (Selzer, 2000).

Betulinic acid has been demonstrated to induce programmed cell death with melanoma and certain neuroectodermal tumor cells. It has been demonstrated currently that the treatment of cultured UISO-Mel-1 (human melanoma cells) with betulinic acid leads to the activation of p38 and stress activated protein kinase/c-Jun NH2-terminal kinase (a widely accepted pro-apoptotic mitogen-activated protein kinases (MAPKs)) with no change in the phosphorylation of extracellular signal-regulated kinases (anti-apoptotic MAPK). Moreover, these results support a link between the MAPKs and reactive oxygen species (ROS).

These data provide additional insight in regard to the mechanism by which betulinic acid induces programmed cell death in cultured human melanoma cells, and it likely that similar responses contribute to the anti-tumor effect mediated with human melanoma carried in athymic mice (Tan, 2003).

Glioma

Betulinic acid triggers apoptosis in five human glioma cell lines. Betulinic acid-induced apoptosis requires new protein, but not RNA, synthesis, is independent of p53, and results in p21 protein accumulation in the absence of a cell-cycle arrest. Betulinic acid-induced apoptosis involves the activation of caspases that cleave poly(ADP ribose)polymerase.

Betulinic acid induces the formation of reactive oxygen species that are essential for BA-triggered cell death. The generation of reactive oxygen species is blocked by BCL-2 and requires new protein synthesis but is unaffected by caspase inhibitors, suggesting that betulinic acid toxicity sequentially involves new protein synthesis, formation of reactive oxygen species, and activation of crm-A-insensitive caspases (Wolfgang, 1999).

Head and Neck Carcinoma

In two head and neck squamous carcinoma (HNSCC) cell lines betulinic acid induced apoptosis, which was characterized by a dose-dependent reduction in cell numbers, emergence of apoptotic cells, and an increase in caspase activity. Western blot analysis of the expression of various Bcl-2 family members in betulinic acid–treated cells showed, surprisingly, a suppression of the expression of the pro-apoptotic protein Bax but no changes in Mcl-1 or Bcl-2 expression.

These data clearly demonstrate for the first time that betulinic acid has apoptotic activity against HNSCC cells (Thurnher et al., 2003).

Results showed that ACP-a1 significantly inhibited the growth of hepatoma H22 transplanted in mice and prolonged the survival time of H22 tumor-bearing mice. As well, the body weight, peripheral white blood cells (WBC), thymus index and spleen index of H22 tumor-bearing were also improved after ACP-a1 treatment.

Furthermore, ACP-a1 could promote the secretion of serum cytokines in H22 tumor-bearing mice, such as IL-2, TNF-α and IFN-γ. Taken together, these results indicate that ACP-a1 inhibits tumor growth in vivo at least partly via improving immune responses of the host organism, and seems to be safe and effective as a novel agent with immunomodulatory activity for the use of anti-tumor therapy (Li et al., 2013).

Chemo-sensitizer; Liver carcinoma

The monkshood polysaccharide (MPS), aconitum, was studied for its combined synergistic effect, with Adriamycin (ADM), versus Adriamycin alone. Both treatments were delivered via long circulating temperature-sensitive liposome (LTSL) in H22, liver carcinoma, tumor-bearing mice. The synergic action of monkshood polysaccharide (MPS) and adriamycin (ADM) long circulating temperature-sensitive liposome (ALTSL) in targeting therapy for H22 tumor-bearing mice was studied

Outcomes assessed included tumor weight, as an index for anti-tumorigenic effect, as well as survival time. Natural killer cell activity of NK cells was higher in the ALTSL group versus the control, but lower than the MPS + ALTSL group. Lymphocyte transformation in the MPS + ALTSL group was markedly improved (P < 0.01) relative to the ALTSL.

Results of RT-PCR indicated that the expression of IL-2 mRNA and IL-12 mRNA, in lymphocytes, in ALTSL group were significantly higher than those in the control. However, expression of IL-2 mRNA and IL-12 mRNA was much higher in the MPS + ALTSL versus the ALTSL group.

LTSL can increase the anti-tumor effect and decrease the
side-effects, such as cytotoxicity, of ADM. MPS combined with ALTSL can enhance natural killer cell activity and transformation of T cells, creating a synergistic anti-tumorigenic effect (Dong et al., 2006).

Leukemia

Two amide alkaloids, named 3-isopropyl-tetrahydropyrrolo [1,2-a]
pyrimidine-2,4(1H,3H)-dione (1) and 1-acetyl-2,3,6-triisopropyl-tetrahydropyrimidin-4(1H)-one (2), were isolated from the roots of Aconitum taipeicum. These compounds exhibited more significant cell growth-inhibitory activities against human promyelocytic leukemia (HL-60) cells than adriamycin, with the IC(50) of 1.1 ± 0.03 µg/mL and 1.6 ± 0.07 µg/mL respectively. In addition, two compounds showed anti-tumor activities against K562 cells as well (Xu, Guo & Wu, 2010).

Oxymatrine or Compound Matrine (Ku Shen)

Cancer: Sarcoma, pancreatic, breast, liver, lung, oral., rectal., stomach, leukemia, adenoid cystic carcinoma

Action: Anti-inflammatory, anti-proliferative, chemo-sensitizer, chemotherapy support, cytostatic, radiation support, anti-angiogenesis

Ingredients: ku shen (Sophora flavescens), bai tu ling (Heterosmilax chinensis).

TCM functions: Clearing Heat, inducing diuresis, cooling Blood, removing Toxin, dispersing lumps and relieving pain (Drug Information Reference in Chinese: See end, 2000-12).

Indications: Pain and bleeding caused by cancer.

Dosage and usage:

Intramuscular injection: 2-4 ml each time, twice daily; intravenous drip: 12 ml mixed in 200 ml NaCl injection, once daily. The total amount of 200 ml administration makes up a course of treatment. 2-3 consecutive courses can be applied.

Anti-cancer

Oxymatrine, isolated from the dried roots of Sophora flavescens (Aiton), has a long history of use in traditional Chinese medicine to treat inflammatory diseases and cancer. Kushen alkaloids (KS-As) and kushen flavonoids (KS-Fs) are well-characterized components in kushen. KS-As containing oxymatrine, matrine, and total alkaloids have been developed in China as anti-cancer drugs. More potent anti-tumor activities were identified in KS-Fs than in KS-As in vitro and in vivo (Sun et al., 2012). The four major alkaloids in compound Ku Shen injection are matrine, sophoridine, oxymatrine and oxysophocarpine (Qi, Zhang, & Zhang, 2013).

Sarcoma

When a high dose was used, the tumor-inhibitory rate of oxymatrine was 31.36%, and the vascular density of S180 sarcoma was lower than that in the control group and the expression of VEGF and bFGF was down-regulated. Oxymatrine hence has an inhibitory effect on S180 sarcoma and strong inhibitory effects on angiogenesis. Its mechanism may be associated with the down-regulating of VEGF and bFGF expression (Kong et al., 2003).

T Cell Leukemia

Matrine, a small molecule derived from the root of Sophora flavescens AIT was demonstrated to be effective in inducing T cell anergy in human T cell leukemia Jurkat cells.

The results showed that passage of the cells, and concentration and stimulation time of ionomycin on the cells could influence the ability of T cell anergy induction.

The cells exposed to matrine showed markedly decreased mRNA expression of interleukin-2, an indicator of T cell anergy. Pre-incubation with matrine or ionomycin could also shorten extracellular signal-regulated kinase (ERK) and suppress c-Jun NH(2)-terminal kinase (JNK) expression on the anergic Jurkat cells when the cells were stimulated with anti-OKT-3 plus anti-CD28 antibodies. Thus, matrine is a strong candidate for further investigation as a T cell immunotolerance inducer (Li et al., 2010).

Osteosarcoma

Results showed that treatment with oxymatrine resulted in a significant inhibition of cell proliferation and DNA synthesis in a dose-dependent manner, which has been attributed to apoptosis. Oxymatrine considerably inhibited the expression of Bcl-2 whilst increasing that of Bax.

Oxymatrine significantly suppressed tumor growth in female BALB/C nude mice bearing osteosarcoma MNNG/HOS xenograft tumors. In addition, no evidence of drug-related toxicity was identified in the treated animals by comparing the body weight increase and mortality (Zhang et al., 2013).

Pancreatic Cancer

Oxymatrine decreased the expression of angiogenesis-associated factors, including nuclear factor κB (NF-κB) and vascular endothelial growth factor (VEGF). Finally, the anti-proliferative and anti-angiogenic effects of oxymatrine on human pancreatic cancer were further confirmed in pancreatic cancer xenograft tumors in nude mice (Chen et al., 2013).

Furthermore, oxymatrine treatment led to the release of cytochrome c and activation of caspase-3 proteins. Oxymatrine can induce apoptotic cell death of human pancreatic cancer, which might be attributed to the regulation of Bcl-2 and IAP families, release of mitochondrial cytochrome c and activation of caspase-3 (Ling et al., 2011).

Rectal Carcinoma

Eighty-four patients diagnosed with rectal carcinoma at the People”s Hospital of Yichun city in Jiangxi province from September 2006 to September 2011, were randomly divided into two groups: therapeutic group and control group. The patients in the therapeutic group were treated with compound matrine and intensity modulated radiation therapy (IMRT) (30 Gy/10 f/2 W), while the patients in control group were treated with IMRT.

The clinical effect and survival rate in the therapeutic group were significantly higher (47.6%) than those in the control group (21.4%). All patients were divided by improvement, stability, and progression of disease in accordance with Karnofsky Performance Scale (KPS). According to the KPS, 16 patients had improvement, 17 stabilized and 9 had disease progress in the therapeutic group.

However, the control group had 12 improvements, 14 stabilized, and 16 disease progress. Quality of life in the therapeutic group was higher than that in the control group by rank sum test. The level of sIL-2R and IL-8 in the therapeutic group was lower on the first and 14th day, post radiation, when compared to the control group. However, there was no significant difference on the first day and 14th day, between both experimental groups post therapy, according to the student test. Compound matrine can decrease the side-effects of IMRT, significantly inhibit sIL-2R and IL-8 in peripheral blood from radiation, and can improve survival quality in patients with rectal cancer (Yin et al., 2013).

Gastric Cancer

Seventy-six cases of advanced gastric cancer were collected from June 2010 to November 2011, and randomly divided into either an experimental group or control group. Patients in the two groups were treated with matrine injection combined with SP regimen, or SP regimen alone, respectively. The effectiveness rate of the experimental group and control group was 57.5% and 52.8% respectively.

The treatment of advanced gastric cancer with matrine injection, combined with the SP regimen, can significantly improve levels of white blood cells and hemoglobin, liver function, incidence of diarrhea and constipation, and neurotoxicity, to improve the quality of life in patients with advanced gastric cancer (Xia, 2013).

Adenoid Cystic Carcinoma

Adenoid cystic carcinoma (ACC-2) cells were cultured in vitro. MTT assay was used to measure the cell proliferative effect. Compound radix Sophorae flavescentis injection could inhibit the proliferation of ACC-2 cells in vitro, and the dosage effect relationship was significant (P < 0.01). Radix Sophorae flavescentis injection could enhance ACC-2 cells Caspase-3 protein expression (P < 0.05 or P < 0.01), in a dose-dependent manner. It also could effectively restrain human adenoid cystic carcinoma ACC-2 cells Caspases-3 protein expression, and induce apoptosis, inhibiting tumor cell proliferation (Shi & Hu, 2012).

Breast Cancer; Chemotherapy

A retrospective analysis of oncological data of 70 postoperative patients with breast cancer from January 2008 to August 2011 was performed. According to the treatment method, the patients were divided into a therapy group (n=35) or control group (n=35). Patients in the control group were treated with the taxotere, adriamycin and cyclophosphamide regimen (TAC). The therapy group was treated with a combination of TAC and sophora root injection. Improved quality of life and incidence of adverse events, before and after treatment, for 2 cycles (21 days for a cycle) were compared.

The improvement rate of total quality of life in the therapy group was higher than that of the control group (P < 0.05). The drop of white blood cells and platelets, gastrointestinal reaction, elevated SGPT, and the incidence of hair loss in the therapy group were lower than those of the control group (P < 0.05).

Sophora root injection combined with chemotherapy in treatment of breast cancer can enhance the effect of chemotherapy, reduce toxicity and side-effects, and improve quality of life (An, An, & Wu, 2012).

Lung cancer; Pleural Effusion

The therapeutic efficiency of Fufang Kushen Injection Liquid (FFKSIL), IL-2, α-IFN on lung cancer accompanied with malignancy pleural effusions, was observed.

One hundred and fifty patients with lung cancer, accompanied with pleural effusions, were randomly divided into treatment and control groups. The treatment group was divided into three groups: injected FFKSIL plus IL-2, FFKSIL plus α-tFN, and IL-2 plus α>-IFN, respectively. The control group was divided into three groups and injected FFKSIL, IL-2 and α>-IFN, respectively. The effective rate of FFKSIL, IL-2, and α-IFN in a combination was significantly superior to single pharmacotherapy. The effective rate of fufangkushen plus ct-IFN was highest. The effect of FFKSIL, IL-2, and α-IFN, in a combination, on lung cancer with pleural effusions was significantly better than single pharmacotherapy. Moreover, the effect of FFKSIL plus IL-2 or α-IFN had the greatest effect (Hu & Mei, 2012).

Gastric Cancer

Administration of FFKSIL significantly enhanced serum IgA, IgG, IgM, IL-2, IL-4 and IL-10 levels, decreased serum IL-6 and TNF-αlevels, lowered the levels of lipid peroxides and enhanced GSH levels and activities of GSH-dependent enzymes. Our results suggest that FFKSIL blocks experimental gastric carcinogenesis by protecting against carcinogen-induced oxidative damage and improving immunity activity (Zhou et al., 2012).

Colorectal Cancer; Chemotherapy

Eighty patients after colorectal cancer resection were randomly divided into two groups: 40 patients in the control group were treated with routine chemotherapy including 5-fluorouridine(5-FU), calcium folinate(CF) and oxaliplatin, and 40 patients in the experimental group were treated with the same chemotherapy regime combined with 20 mLád-1 compound Kushen injection, for 10d during chemotherapy. In the control group the numbers of CD3+,CD4+T cells,NK cells and CD4+/CD8+ ratio significantly declined relative to prior to chemotherapy (P < 0.05), while CD8+T lymphocyte number increased significantly. In the experimental group, there were no significant differences between the numbers of CD3+,CD4+,CD8+T cells ,NK cells, and CD4+/CD8+ ratio, before and after chemotherapy (P > 0.05).

Compound Kushen injection can improve the immunologic function of patients receiving chemotherapy after colorectal cancer resection (Chen, Yu, Yuan, & Yuan, 2009).

NSCLC; Chemotherapy

A total of 286 patients with advanced NSCLC were enrolled for study. The patients were treated with either compound Kushen injection in combination with NP (NVB + CBP) chemotherapy (vinorelbine and carboplatin, n = 144), or with NP (NVB + CBP) chemotherapy alone (n = 142). The following indicators were observed: levels of Hb, WBC, PLT and T cell subpopulations in blood, serum IgG level, short-term  efficacy, adverse effects and quality of life.

The gastrointestinal reactions and the myelosuppression in the combination chemotherapy group were alleviated when compared with the chemotherapy alone group, showing a significant difference (P < 0.05). CD (8)(+) cells were markedly declined in the combination chemotherapy group, and the CD (4)(+)/CD (8)(+) ratio showed an elevation trend in the chemotherapy alone group. The Karnofsky Performance Scale (KPS) scores and serum IgM and IgG levels were higher in the combination chemotherapy group than those in the chemotherapy alone group (P < 0.01 and P < 0.05).

The compound Kushen injection plus NP chemotherapy regimen showed better therapeutic effect, reduced adverse effects of chemotherapy and improved the quality of life in patients with stage III and IV NSCLC (Fan et al., 2010).

Lung Adenocarcinoma

Different concentrations of matrine injection could inhibit the growth of SPCA/I human lung adenocarcinoma cells. There was a positive correlation between the inhibition rate and the drug concentration. Different concentrations of matrine injection combined with anti-tumor drugs had a higher growth inhibition rate than anti-tumor drugs alone. Matrine injection has direct growth suppression effect on SPCA/I human lung adenocarcinoma cells and SS+ injection combined with anti-tumor drugs shows a significant synergistic effect on tumor cells (Zhu, Jiang, Lu, Guo, & Gan, 2008).

Liver Cancer

Fifty-seven patients with unresectable primary liver cancer were randomly divided into 2 groups. The treatment group with 27 cases was treated by TACE combined with composite Kushen injection, and the control group with 30 cases was treated by TACE alone. One, two, and three year survival rates of the treatment group were 67%, 48%, and 37% respectively, and those of control group were 53%, 37%, and 20% respectively. There were significant differences between both groups (P < 0.05).

Combined TACE with composite Kushen injection can increase the efficacy of patients with unresectable primary liver cancer (Wang & Cheng, 2009).

Chemotherapy

Ten RCTs were included in a meta-analysis, whose results suggest that compared with chemotherapy alone, the combination had a statistically significant benefit in healing efficacy and improving quality of life. As well,  the combination also had a statistically significant benefit in myelosuppression, white blood cell, hematoblast, liver function and in reducing the gastroenteric reaction, decreasing the of CD3, CD4, CD4/CD8, and NK cells (Huang et al., 2011).

Colorectal Cancer, NSCLC, Breast Cancer; Chemotherapy

Fufang kushen Injection might improve the efficacies of chemotherapy in patients with colorectal cancer, NSCLC and breast cancer.

The results of a meta-analysis of 33 studies of randomized controlled trials with a total of 2,897 patients demonstrated that the short-term efficacies in patients with colorectal cancer, NSCLC, and breast cancer receiving Fufangkushen Injection plus chemotherapy were significantly better than for those receiving chemotherapy alone. However the results for patients with gastric cancer on combined chemotherapy were not significantly different from those for patients on chemotherapy alone (Fang, Lin, & Fan, 2011).

Kanglaite injection (KLT)

Cancer: Lung, stomach, liver, kidney, breast, nasopharynx, esophagus, pancreas, colon-rectum, ovarian, prostate, lymphoma, leukemia

Action: Anti-tumoral, immunomodular, chemotherapy support, radiation support

Ingredients: yi yi ren (Coix Lacryma-jobi seed oil, CLSO).

Indications: primary NSCLC and primary liver cancer, which are not suitable for surgery, of qi and yin deficiency, lingering “Dampness due to Spleen deficiency types”. It has synergic effect when combined with radiotherapy or chemotherapy. It has certain anti-cachexia and analgesic effects for middle or late-stage tumor patients.

Dosage and usage:

Slow intravenous drip: 200 ml, once daily, 21 days as a course of treatment with 3-5 days interval.

When combined with radiotherapy or chemotherapy, the dosage can be reduced according to the practical conditions. (Drug Information Reference in Chinese, 2000. See end).

Invented by the famous pharmacological professor, Prof. Li Dapeng, Kanglaite Injection (KLT) has been listed by the Chinese government as a “State Basic Drug”, a “State Basic Medical Insurance Drug” and a “State Key New Drug”.

Based on pre-clinical studies at John Hopkins University, USA, tumor-inhibitive rate of KLT on transplanted breast carcinoma induced by cell strain MDA-MB-231 was over 50%. KLT could inhibit the expression of COX2 of the strain in vitro and act as an inhibitor of fatty acid synthase.

The broad ranged basic studies in China also revealed KLT different mechanisms such as inducing cancer cell apoptosis, inhibiting angiogenesis, reversing MDR and regulating gene expression of Fas/Apo-1 and Bcl-2.

Both Chinese and overseas clinical experiences have shown that KLT has proven effect in the treatment of cancers mainly at the sites of lung, breast, liver, nasopharynx, esophagus, stomach, pancreas, kidney, colon-rectum, ovary and prostate. This agent is also applied in the treatment of malignant lymphoma and acute leukemia. KLT has brought great benefits to over 500,000 cancer patients in more than 2,000 big or medium hospitals in China since 1997.

The year 1995 witnessed KLT patent certificates granted from China and the USA. In August 1997 the phase III clinical study was successfully completed and the injection was officially launched in China after final approval from the Ministry of Public Health.

Doctors in America carried out a phase 1 study of Kanglaite in 2003. They gave it to 16 people who had different types of cancer including lung, prostate and oesophageal cancers. The results showed people did not have many side-effects but the effect on their cancer varied. Some people showed no response, and their cancers continued to grow. But in others, the cancer stopped growing for a few months.

Standard treatment course for KLT is 200 ml (2 bottles) per day via intravenous drip x 42 days (84 bottles). There is a break for 4-5 days after 21 days. Clinical experiences in China and Russia suggest 2 treatment courses for those with late stage advanced and metastatic tumors for better therapeutic effect and evident prolongation of life (Conti, n.d.).

A consecutive cohort of 60 patients was divided into two groups, the experimental group receiving Kanglaite” Injection combined with chemotherapy and the control group receiving chemotherapy alone. After more than two courses of treatment, efficacy, quality of life and side-effects were evaluated. The response rate and KPS score of the experimental group were significantly improved as compared with those of the control group(P<0.05). In addition, gastrointestinal reactions and bone marrow suppression were significantly lower than in the control group(P<0.05). Kanglaite” Injection enhanced efficacy and reduced the side-effects of chemotherapy, improving quality of life of gastric cancer patients (Zhan et al., 2012).

Lung Cancer

C57BL/6 mice with Lewis lung carcinoma were divided into four groups: the control group (C), cisplatin group (1 mg/kg, DDP), low KLT group (6.25 ml/kg body weight [L]), and high KLT group (12.5 ml/kg body weight [H]). T cell proliferation was determined by the MTT assay. Nuclear factor-kappa B (NF-κB), inhibitor kappa B alpha

(IκBα), IκB kinase (IKK) and epidermal growth factor receptor (EGFR) levels were measured by western blotting. An enzyme-linked immunosorbent assay was used to analyze the expression of interleukin-2 (IL-2).

Intraperitoneal KLT significantly inhibited the growth of Lewis lung carcinoma, and the spleen index was significantly higher in the L and H groups than in the C group. KLT stimulated T cell proliferation in a dose-dependent manner. Treatment with KLT at either 6.25 or 12.5 ml/kg decreased the level of NF-κB in the nucleus in a dose-dependent manner, and KLT markedly decreased the expression of IκBα, IKK and EGFR in the cytoplasm of tumor cells and overall. IL-2 was significantly increased in the supernatant of splenocytes in the H group.

These results demonstrate that KLT has pronounced anti-tumor and immunostimulatory activities in C57BL/6 mice with Lewis lung carcinoma. These may affect the regulation of NF-κB/IκB expression, in addition to cytokines such as IL-2 and EGFR. Further work needs to investigate the relevant signaling pathway effects, but our findings suggest that KLT may be a promising anti-tumor drug for clinical use (Pan et al., 2012).

Skin Keratinocytes

Ultraviolet (UV) radiation plays an important role in the pathogenesis of skin photoaging. Depending on the wavelength of UV, the epidermis is affected primarily by UVB. One major characteristic of photoaging is the dehydration of the skin. Membrane-inserted water channels (aquaporins) are involved in this process. In this study we demonstrated that UVB radiation induced aquaporin-3 (AQP3) down-regulation in cultured human skin keratinocytes. Kanglaite is a mixture consisting of extractions of Coix Seed, which is an effective anti-neoplastic agent and can inhibit the activities of protein kinase C and NF-κB. We demonstrated that Kanglaite inhibited UVB-induced AQP3 down-regulation of cultured human skin keratinocytes. Our findings provide a potential new agent for anti-photoaging (Shan et al., 2012).

Hepatocellular Carcinoma

KLT produced an obvious time and dose-dependent inhibitory effect on HepG2 cells, and marked apoptosis was detected by FCM. The protein of Fas increased by 11.01%, 18.71%, 28.71% and 37.15%; the protein of FasL increased by 1.49%, 1.91%, 3.27% and 3.38% in comparison with the control (P<0.05). Real-time fluorescent quantitative RT-PCR showed that treating HepG2 cells with KLT caused the up-regulation of Fas and FasL mRNA. KLT inhibits HepG2 growth by inducing apoptosis, which may be mediated through activation of the Fas/FasL pathway (Lu et al., 2009).

Glomerular Nephritis

MTT, telomere repeat amplification protocol (TRAP), ELISA, PAGE and silver-stain were applied to detect the growth rate and telomerase activity of mesengial cell (MC) after stimulation of Kang Lai Te (KLT) and IL-1. The growth rate of MC was enhanced by IL-1 stimulation, which was accompanied with a reduction of the activity of telomerase. Adversely, the growth rate of MC was reduced by KLT, which was accompanied with an enhancement of activity of telomerase. Moreover, the growth rate of MC and the activity of telomerase were both inhibited by the combinative use of IL-1 and KLT without any influence from the sequence of their administration. KLT could inhibit proliferation and telomerase activity of MC with or without pre-stimulation with IL-1. KLT might be useful to prevent and treat glomerular nephritis related to MC proliferation (Hu et al., 2005).

Lung Metastasis

To screen the differential expression genes of Kanglaite in anti-tumor metastasis mRNA was extracted and purified from the lung of the mouse with LA795 lung metastasis, and hybridized respectively on 4 096-gene chip. cDNA microarray was scanned for the fluorescent signals and analyzing difference expression. Twenty-seven differential expressed genes were obtained.

Among these genes, 25 were up-regulated and 2 were down-regulated. Twelve of them were Mus musculus cDNA clone. Six genes related with genesis, development and metastasis of tumor. cDNA microarray for analysis of gene expression patterns is a powerful method to identify differential expressed genes. In this study, 6 genes are thought to be associated genes of Kanglaite in anti-tumor metastasis (Wu et al., 2003).

Lung Cancer; Chemo Side Effects

Sixteen reports were included in the meta-analysis. The quality of 16 studies was low. Pooling data of 5 studies indicated that the effect of Kanglaite+NP (Vinorelbine+Cisplatin) was better than NP with RR 1.46, 95% Confidence Interval 1.13 to 1.91. Pooling data of 3 studies of MVP (Mitomycin+Vindsine+ Cisplatin) plus Kanglaite indicated that the effect was better with RR 1.84, 95%CI 1.22 to 2.76. Pooling data of 2 studies showed that the effect of GP (Gemcitabine+Cisplatin) plus Kanglaite was better than GP with RR 1.63, 95%CI 1.09 to 2.43.

Fourteen studies revealed that Kanglaite may reduce the side-effects induced by regular treatment. Ten studies showed regular treatment plus Kanglaite can stabilize/improve quality of life (Zhu et al., 2009).

Apoptosis

Some studies show Kanglaite could inhibit some anti-apoptotic genes and activate some pro-apoptotic genes. Its injection solution is one of the new anti-cancer medicines that can significantly inhibit various kinds of tumor cells, so it has become the core of research into how to further explore KLT injection to promote tumor cell apoptosis by impacting on related genes (Lu et al., 2008).

Astragalus (huang qi)

Cancer: Non-small-cell lung cancer, breast, colon, stomach

NSCLC; Chemotherapy

Guo et al. (2012) reported that treatment with Astragalus polysaccharide (APS) injections integrated with vinorelbine and cisplatin significantly improved quality of life in patients with advanced non-small-cell lung cancer over vinorelbine and cisplatin alone.

NSCLC

Astragalus injection (AI) combined with chemotherapy can significantly improve the QOF in NSCLC patients of advanced stage. The effective rate in the treated group was 40.0% and in the control group was 36.7%, the mean remission rate in the treated and control group was 5.4 months and 3.3 months, the median survival period 11 months and 7 months, and the 1-year survival rate 46.75% and 30.0%, respectively; the differences of these indexes between the two groups were all significant (P < 0.05). Moreover, the clinical improving rate and QOF elevation rate in the treated group was 80.4% and 43.3%, as compared with those in the control group (50.0% and 23.3% respectively); the difference was also significant (P < 0.01) (Zou & Liu, 2003).

Breast Cancer

In physiological dose E2, Astragalus mongholicus injection inhibited MCF-7 breast cancer cells proliferation at all concentration groups. As time lasting, Astragalus mongholicus injection showed better inhibitory effect than TAM (P<0.05). Among 2 x 10(-1) g/mL-2 x 10(-4) g/mL concentration, Astragalus mongholicus injection significantly increased the proliferative percent of G0/G1 and S-phase cell, decreased percent of G2-M phase cell (P<0.05) at 24 hours. After cocultured 72 hours, Astragalus mongholicus injection increased the rate of apoptosis to 16.7% at 2 x 10(-1) g/mL concentration (Zhou, Liu, & Tan, 2009).

Acute Exacerbations, Respiratory Failure in Chronic Obstructive Pulmonary Disease

A total of 112 patients with acute chronic obstructive pulmonary disease (AECOPD)were randomly divided into the treatment group (56 cases) and control group (56 cases). The treatment group received a 40 mL astragalus injection, with 5% glucose, 250 mL intravenous drip once a day at the start of conventional therapy. The control group received conventional therapy only. The therapeutic course of both groups was 14 days, and clinical therapeutic effects were observed. Serum levels of TNF-α>, IL-8, IL-2, lung function and blood gas analysis index of both groups were measured before and after treatment. The treatment group”s effectiveness rate was 94.64%, compared to the control group”s 67.86%, which was statistically significant (P<0.05).

Astragalus injection may significantly decrease the serum levels of TNF-α and IL-8, and increase the level of IL-2. It may improve the lung function and the curative effect in the patients with AECOPD (Xiong, Guo, & Xiong, 2013).

Residual Renal Function

The effect of astragalus injection on hemodialysis patient”s RRF (residual renal function, RRF) was observed.

Sixty hemodialysis patients with a RRF of more than 2ml/min were randomly divided into either an astragalus injection treatment group or a control group treated with normal saline. One hour prior to hemodialysis completion, the treatment group was administered an astragalus injection of 30ml, while the control group was given 30 ml of normal saline. Follow up after 6 months compared data of daily urine output and RRF.

Astragalus injection can potentially delay the rate of daily urine output reduction and protect RRF to some extent (Qi et al., 2013).

Stomach Cancer, Colon Cancer; Oxaliplatin-induced Neurotoxicity

40 patients with stomach or colon cancer were enrolled in the study. Patients comprised of 23 men and 17 women, from the ages of 32-75 years (mean age 60 years), and were randomly divided into two groups: the test group and the control group (20 cases in each group). All patients were treated with one cycle of an Oxaliplatin-containing chemotherapy regimen, entailing: oxaliplatin 130 mg/m2 on day 1, fluorouracil 0.5 g on days 1-5, and calcium foliate 0.2 g on days 1-5. In the test group 30 ml of Huangqi injection was added to the regimen on days 1-7. The manifestation of peripheral neurotoxic reactions were observed and nerve growth factor levels were measured.

In the control group, 2 patients had grade 0 toxicity, 10 had grade 1 toxicity, 6 had grade 2 toxicity, and 2 had grade 3 toxicity. In the test group, 14 patients had grade 0 toxicity and 6 had grade 1 toxicity. The incidence rate of neurotoxicity in the test and control groups was 30% and 90%, respectively. In the test and control groups, the nerve growth factor levels were (167 ± 10) ng/ml and (204 ± 19) ng/ml before chemotherapy, as well as (152 ± 8) ng/ml and (133 ± 12) ng/ml 2 days after chemotherapy, respectively. In the control group, the nerve growth factor levels were markedly decreased 2 days after chemotherapy compared to before chemotherapy. The difference between the two groups was statistically significant (P < 0.01).

Huangqi injection has some degree of efficacy in the prevention and treatment of Oxaliplatin-induced neurotoxicity (Cui, Li, Tan, & Li, 2009).

Myelosuppression

Astragalus membranaceus injection (AMI), administered at (500 mg/kg) improved the hematopoietic microenvironment by enhancing the BMSC survival and proliferation of colony-forming unit-fibroblast (CFU-F) formation, production of IL-6 as well as Granulocyte-macrophage colony-stimulating factor (GM-CSF) by BMSC and bcl-2 protein and mRNA expression in BMSC, which promoted myelopoiesis. The data may provide a mechanistic basis for applying this ancient Chinese herb to promote hematopoiesis as an efficacious adjuvant therapy against myelosuppression induced by anti-cancer therapy (Zhu & Zhu, 2007).
