Ursolic acid

Cancer:
Glioblastoma, Lung, breast, colorectal, gastric, esophageal squamous carcinoma, prostate

Action:

Mitochondrial function, reactive oxygen species (ROS) generation.

Cytostatic, anti-inflammatory, chemo-prevention, COX-2 inhibitor, suppresses NF- κ B, induces IL-1 β , induces apoptosis

Ursolic acid, a pentacyclic triterpene acid found ubiquitously in the plant kingdom, including Rosmarinus officinalis (L.), Salvia officinalis (L.), Prunella vulgaris (L.), Psychotria serpens (L.) and Hyptis capitata (Jacq.). It has been shown to suppress the expression of several genes associated with tumorigenesis resulting in anti-inflammatory, anti-tumorigenic and chemo-sensitizing effects (Liu, 1995).

Glioblastoma Cancer

Ursolic acid, a natural pentacyclic triterpenic acid, possesses anticancer potential and diverse biological effects, but its correlation with glioblastoma multiforme cells and different modes of cell death is unclear. We studied the cellular actions of human GBM DBTRG-05MG cells after ursolic acid treatment and explored cell-selective killing effect of necrotic death as a cell fate.

Ursolic acid effectively reversed TMZ resistance and reduced DBTRG-05MG cell viability. Surprisingly, ursolic acid failed to stimulate the apoptotic and autophagic-related signaling networks. The necrotic death was characterized by annexin V/PI double-positive detection and release of HMGB1 and LDH. These ursolic acid-elicited responses were accompanied by ROS generation and glutathione depletion. Rapid mitochondrial dysfunction was paralleled by the preferential induction of necrosis, rather than apoptotic death. MPT is a phenomenon to provide the onset of mitochondrial depolarization during cellular necrosis. The opening of MPT pores that were mechanistically regulated by CypD, and ATP decline occurred in treated necrotic DBTRG-05MG cells. Cyclosporine A (an MPT pore inhibitor) prevented ursolic acid-provoked necrotic death and -involved key regulators.

The study by Lu et al., (2014) is the first to report that ursolic acid-modified mitochondrial function triggers defective death by necrosis in DBTRG-05MG cells rather than augmenting programmed death.

Gastric Cancer

Ursolic acid (UA) inhibits growth of BGC-803 cells in vitro in dose-dependent and time-dependent manner. Treated with UA in vivo, tumor cells can be arrested to G0/G1 stage. The apoptotic rate was significantly increased in tumor cells treated with UA both in vitro and in vivo. These results indicated that UA inhibits growth of tumor cells both in vitro and in vivo by decreasing proliferation of cells and inducing apoptosis (Wang et al., 2011).

Esophageal Squamous Carcinoma

The anti-neoplastic effects of combinations of anti-cancer drugs (5-fluorouracil, irinotecan and cisplatin) and triterpenes (ursolic acid, betulinic acid, oleanolic acid and a Japanese apricot extract (JAE) containing triterpenes) on esophageal squamous carcinoma cells were examined by the WST-8 (2-(2-methoxy- 4-nitrophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium, monosodium salt) assay in vitro and by an animal model in vivo. Triterpenes and JAE showed additive and synergistic cytotoxic effects, respectively, on esophageal squamous carcinoma cells (YES-2 cells) by combinational use of 5-fluorouracil. JAE and 5-fluorouracil induced cell-cycle arrest at G2/M phase and at S phase, respectively, and caused apoptosis in YES-2 cells.

These results suggest that triterpenes, especially JAE, are effective supplements for enhancing the chemotherapeutic effect of 5-fluorouracil on esophageal cancer (Yamai et al., 2009).

COX-2 Inhibitor

Subbaramaiah et al. (2000) studied the effects of ursolic acid, a chemo-preventive agent, on the expression of cyclooxygenase-2 (COX-2). Treatment with ursolic acid suppressed phorbol 12-myristate 13-acetate (PMA)-mediated induction of COX-2 protein and synthesis of prostaglandin E2. Ursolic acid also suppressed the induction of COX-2 mRNA by PMA. Increased activator protein-1 activity and the binding of c-Jun to the cyclic AMP response element of the COX-2 promoter, effects were blocked by ursolic acid (Subbaramaiah et al., 2000).

Lung Cancer, Suppresses NF- κB

In terms of general anti-cancer mechanism, ursolic acid has also been found to suppress NF-κB activation induced by various carcinogens through the inhibition of the DNA binding of NF-κB. Ursolic acid also inhibits IκBα kinase and p65 phosphorylation (Shishodia et al., 2003). In particular, ursolic acid has been found to block cell-cycle progression and trigger apoptosis in lung cancer and may hence act as a chemoprevention agent for lung cancer (Hsu et al., 2004).

Breast Cancer

Ursolic acid is a potent inhibitor of MCF-7 cell proliferation. This triterpene exhibits both cytostatic and cytotoxic activity. It exerts an early cytostatic effect at G1 followed by cell death. Results suggest that alterations in cell-cycle phase redistribution of MCF-7 human breast cancer, by ursolic acid, may significantly influence MTT (colorimetric assays) reduction to formazan (Es-Saady et al., 1996).

Induces IL-1 β

Interleukin (IL)-1beta is a pro-inflammatory cytokine responsible for the onset of a broad range of diseases, such as inflammatory bowel disease and rheumatoid arthritis. It has recently been found that aggregated ursolic acid (UA), a triterpene carboxylic acid, is recognized by CD36 for generating reactive oxygen species (ROS) via NADPH oxidase (NOX) activation, thereby releasing IL-1beta protein from murine peritoneal macrophages (pMphi) in female ICR mice. In the present study, Ikeda et al. (2008) investigated the ability of UA to induce IL-1beta production in pMphi from 4 different strains of female mice as well as an established macrophage line. In addition, the different susceptibilities to UA-induced IL-1beta release were suggested to be correlated with the amount of superoxide anion (O2-) generated from the 5 different types of Mphi.

Notably, intracellular, but not extracellular, O2- generation was indicated to play a major role in UA-induced IL-1beta release. Together, these results indicate that the UA-induced IL-1beta release was strain-dependent, and the expression status of CD36 and gp91phox is strongly associated with inducibility.

Induces Apoptosis: Breast Cancer, Prostate Cancer

Ursolic acid (UA) induced apoptosis and modulated glucocorticoid receptor (GR) and Activator Protein-1 (AP-1) in MCF-7 breast cancer cells. UA is a GR modulator and may be considered as a potential anti-cancer agent in breast cancer (Kassi et al., 2009).

UA induces apoptosis via both extrinsic and intrinsic signaling pathways in cancer cells (Kwon et al., 2010). In PC-3 cells, UA inhibits proliferation by activating caspase-9 and JNK as well as FasL activation and Akt inhibition (Zhang et al., 2010). A significant proliferation inhibition and invasion suppression in both a dose- and time-dependent manner is observed in highly metastatic breast cancer MDA-MB-231 cells; this inhibition is related to the down-regulation of MMP2 and u-PA expression (Yeh et al., 2010).

Ursolic acid additionally stimulates the release of cytochrome C in HL-60 cells and breast cancer MCF-7 cells. The activation of caspase-3 in a cytochrome C-dependent manner induces apoptosis via the mitochondrial pathway (Qian et al., 2011).

Colorectal Cancer

Ursolic acid (UA) has strong anti-proliferative and apoptotic effects on human colon cancer HT-29 cells. UA dose-dependently decreased cell proliferation and induced apoptosis, accompanied by activation of caspase 3, 8 and 9. The effects may be mediated by alkaline sphingomyelinase activation (Andersson et al., 2003).

Ursolic acid (UA), using the colorectal cancer (CRC) mouse xenograft model and the HT-29 human colon carcinoma cell line, was evaluated for its efficacy against tumor growth in vivo and in vitro, and its molecular mechanisms were investigated. It was found that UA inhibits cancer growth without apparent toxicity. Furthermore, UA significantly suppresses the activation of several CRC-related signaling pathways and alters the expression of critical target genes. These molecular effects lead to the induction of apoptosis and inhibition of cellular proliferation.

These data demonstrate that UA possesses a broad range of anti-cancer activities due to its ability to affect multiple intracellular targets, suggesting that UA could be a novel multipotent therapeutic agent for cancer treatment (Lin et al., 2013).

Action: Anti-tumor, inhibits tumor cell migration and invasion

Ursolic acid (UA) is a sort of pentacyclic triterpenoid carboxylic acid purified from natural plant. UA has a series of biological effects such as sedative, anti-inflammatory, anti-bacterial, anti-diabetic, antiulcer, etc. It is discovered that UA has a broad-spectrum anti-tumor effect in recent years, which has attracted more and more scholars’ attention. This review explained anti-tumor actions of UA, including (1) the protection of cells’ DNA from different damages; (2) the anti-tumor cell proliferation by the inhibition of epidermal growth factor receptor mitogen-activated protein kinase signal or of FoxM1 transcription factors, respectively; (3) antiangiogenesis, (4) the immunological surveillance to tumors; (5) the inhibition of tumor cell migration and invasion; (6) the effect of UA on caspase, cytochromes C, nuclear factor kappa B, cyclooxygenase, tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) or mammalian target of rapamycin signal to induce tumor cell apoptosis respectively, and etc. Moreover, UA has selective toxicity to tumor cells, basically no effect on normal cells.

Inhibition of Epidermal Growth Factor Receptor/ Mitogen-Activated Protein Kinase Pathway
Activation of mitogen-activated protein kinase (MAPK) allows cell excessive proliferation involved in the carcinogenic process (Park et al., 1999). Subfamilies of MAPK, metastasis.(24) Otherwise, UA suppresses the activation of NF-κB and down-regulation of the MMP-9 protein, which in turn contributes to its inhibitory effects on IL-1β or tumor necrosis factor α (TNF-α)-induced C6 glioma cell invasion (Huang et al., 2009).

U A suppresses inter cellular adhesion molecules-1 (ICAM-1) expression of non-small cell lung cancer (NSCLC) H3255, A549, Calu-6 cells, and significantly inhibits fibronectin expression in a concentration-dependent way. UA significantly suppresses the expression of MMP-9 and MMP-2 and inhibits protein kinase C activity in test cell lines, at the same time, UA reduces cell invasion in a concentration-dependent manner (Huang et al., 2011).

Cancer: Multiple myeloma

Action: Anti-inflammatory, down-regulates STAT3

When dealing with the multiple myeloma, by the way of activating the proto-oncogene-mediated c-Src, JAK1, JAK2, and ERKs, ursolic acid (UA) can not only inhibit the expression of IL-6-induced STAT3 but also downregulates the STAT3 by regulating gene products, such as cyclin D1, Bcl-2, Bcl-xL, surviving, Mcl-1 and VEGF. Above all, UA can inhibit the proliferation of multiple myeloma cells and induce apoptosis, to arrest cells at G1 phase and G0 phase of cell cycle (Pathak et al., 2007).

The essential oils of ginger (Zingiber officinale) and turmeric (Curcuma longa) contain a large variety of terpenoids, some of which possess anticancer, anti-ulcer, and antioxidant properties. Despite their importance, only four terpene synthases have been identified from the Zingiberaceae family: (+)-germacrene D synthase and (S)-β-bisabolene synthase from ginger rhizome, and α-humulene synthase and β-eudesmol synthase from shampoo ginger (Zingiber zerumbet) rhizome (Koo et al., 2012).

Cancer: Colorectal

Wong et al., have previously reported Signal Transducer and Activator of Transcription 3 (STAT3) to be constitutively activated in aldehyde dehydrogenase (ALDH)(+)/cluster of differentiation-133 (CD133)(+) colon cancer-initiating cells. In the present study they tested the efficacy of inhibiting STAT3 signaling in human colon cancer-initiating cells by ursolic acid (UA), which exists widely in fruits and herbs.

ALDH(+)/CD133(+) colon cancer-initiating cells. UA also reduced cell viability and inhibited tumor sphere formation of colon cancer-initiating cells, more potently than two other natural compounds, resveratrol and capsaicin. UA also inhibited the activation of STAT3 induced by interleukin-6 in DLD-1 colon cancer cells. Furthermore, daily administration of UA suppressed HCT116 tumor growth in mice in vivo.

Their results suggest STAT3 to be a target for colon cancer prevention. UA, a dietary agent, might offer an effective approach for colorectal carcinoma prevention by inhibiting persistently activated STAT3 in cancer stem cells.

Cancer: Gastric

Action: Attenuates nephrotoxicity, anti-inflammatory, anti-oxidant, inhibits TNF- α , induces apoptosis, COX-2 down-regulation

Inhibits TNF- α

Moutan Cortex, the root bark of Paeonia suffruticosa Andrews, has been used extensively as a traditional medicine for treatment of various diseases such as atherosclerosis, infection, and inflammation. Previous studies have revealed that the extracts of Moutan Cortex can inhibit nitric oxide and TNF- α in activated mouse peritoneal macrophages (Chung et al., 2007).

A variety of compounds including paeonoside, paeonolide, apiopaeonoside, paeoniflorin, oxypaeoniflorin, benzoyloxypaeoniflorin, benzoylpaeoniflorin, paeonol, and sugars have been identified in Moutan Cortex (Chen et al., 2006).

Attenuates Nephrotoxicity

Paeonol, a major compound of Moutan Cortex, has been found to attenuate cisplatin-induced nephrotoxicity in mice. Cisplatin is an effective chemotherapeutic agent that is used for the treatment of a variety of cancers; however, its nephrotoxicity limits the use of this drug.

Balb/c mice (6 to 8  w of age, weighing 20 to 25  g) were administered with Moutan Cortex (300  mg/kg) or paeonol (20 mg/kg) once a day. At day 4, mice received cisplatin (30, 20, or 10   mg/kg) intraperitoneally.

The paeonol-treated group showed marked attenuation of serum creatine and blood urea nitrogen levels as well as reduced levels of pro-inflammatory cytokines and nitric oxide when compared to the control group. In addition, the paeonol-treated group showed prolonged survival and marked attenuation of renal tissue injury. Taken together, these results demonstrated that paeonol can prevent the renal toxic effects of cisplatin (Lee et al., 2013).

Paeonol, a major phenolic component of Moutan Cortex, has various biological activities such as anti-aggregatory, anti-oxidant, anxiolytic-like, and anti-inflammatory functions (Ishiguro et al., 2006). In this study, paeonol treatment significantly reduced the elevated levels of serum creatinine and BUN. In addition, the role of pro-inflammatory cytokines in cisplatin-induced acute renal failure has been well documented (Faubel et al., 2007; Ramesh & Reeves, 2002), and elevation of the pro-inflammatory cytokines TNF-α and IL-1β as well as that of IL-6 has been demonstrated in humans with acute renal failure (Simmons et al., 2004).

Apoptosis-inducing & Gastric Cancer

Paeonol has significantly growth-inhibitory and apoptosis-inducing effects in gastric cancer cells both in vitro and in vivo. In vitro, paeonol caused dose-dependent inhibition on cell proliferation and induced apoptosis. Cell cycle analysis revealed a decreased proportion of cells in G0/G1 phase, with arrest at S. Paeonol treatment in gastric cancer cell line MFC and SGC-790 cells significantly reduced the expression of Bcl-2 and increased the expression of Bax in a concentration-related manner. Administration of paeonol to MFC tumor-bearing mice significantly lowered the tumor growth and caused tumor regression (Li et al., 2010).

COX-2 Down-regulation

One of the apoptotic mechanisms of paeonol is down-regulation of COX-2. p27 is up-regulated simultaneously and plays an important part in controlling cell proliferation and is a crucial factor in the Fas/FasL apoptosis pathway. Cell proliferation was inhibited by different concentrations of paeonol. By immunocytochemical staining, Ye et al. (2009) found that HT-29 cells treated with paeonol (0.024-1.504 mmol/L) reflected reduced expression of COX-2 and increased expression of p27 in a dose-dependent manner. RT-PCR showed that paeonol down-regulated COX-2 and up-regulated p27 in a dose- and time-dependent manner in HT-29 cells.

Geniposide –Penta-acetyl Geniposide (Ac)5GP

Cancers:
Glioma, melanoma, liver, hepatocarcinogenesis, hepatoma, prostate, cervical

Action: Cytostatic, induces apoptosis

Gardenia, the fruit of Gardenia jasminoides Ellis, has been widely used to treat liver and gall bladder disorders in Chinese medicine. It has been shown recently that geniposide, the main ingredient of Gardenia fructus , exhibits anti-tumor effect.

Hepatocarcinogenesis, Glioma

It has been demonstrated that (Ac)5GP plays more potent roles than geniposide in chemoprevention. (Ac)5GP decreased DNA damage and hepatocarcinogenesis, induced by aflatoxin B1 (AFB1), by activating the phase II enzymes glutathione S-transferase (GST) and GSH peroxidase (GSH-Px). It reduced the growth and development of inoculated C6 glioma cells, especially in pre-treated rats. In addition to the preventive effect, (Ac)5GP exerts its actions on apoptosis and growth arrest.

Treatment of (Ac)5GP caused DNA fragmentation of glioma cells. (Ac)5GP induced sub- G1 peak through the activation of apoptotic cascades PKCdelta/JNK/Fas/caspase8 and caspase 3. It arrested the cell-cycle at G0/ G1 by inducing the expression of p21, thus suppressing the cyclin D1/cdk4 complex formation and the phosphorylation of E2F.

Data from in vivo experiments indicated that (Ac)5GP is not harmful to the liver, heart and kidney. (Ac)5GP is strongly suggested to be an anti-tumor agent for development in the future (Peng, Huang, & Wang, 2005).

Induces Apoptosis

Previous studies have demonstrated the apoptotic cascades protein kinase C (PKC) delta/c-Jun NH2-terminal kinase (JNK)/Fas/caspases induced by penta-acetyl geniposide [(Ac)5GP]. However, the upstream signals mediating PKCdelta activation have not yet been clarified. Ceramide, mainly generated from the degradation of sphingomyelin, was hypothesized upstream above PKCdelta in (Ac)5GP-transduced apoptosis.

After investigation, (Ac)5GP was shown to activate neutral sphingomyelinase (N-SMase) immediately, with its maximum at 15 min. The NGF and p75 enhanced by (Ac)5GP was inhibited when combined with GW4869, the N-SMase inhibitor, indicating NGF/p75 as the downstream signals of N-SMase/ceramide. To evaluate whether N-SMase is involved in (Ac)5GP-transduced apoptotic pathway, cells were treated with (Ac)5GP, alone or combined with GW4869. It was demonstrated that N-SMase inhibition blocked FasL expression and caspase 3 activation. Similarly, p75 antagonist peptide attenuated the FasL/caspase 3 expression. It indicated that N-SMase activation is pivotal in (Ac)5GP-mediated apoptosis.

SMase and NGF/p75 are suggested to mediate upstream above PKCdelta, thus transducing FasL/caspase cascades in (Ac)5GP-induced apoptosis (Peng, Huang, Hsu, & Wang, 2006).

Glioma

Penta-acetyl geniposide [(Ac)(5)GP], an acetylated geniposide product from Gardenia fructus, has been known to have hepato-protective properties and recent studies have revealed its anti-proliferative and apoptotic effect on C6 glioma cells. The anti-metastastic effect of (Ac)(5)GP in the rat neuroblastoma line C6 glioma cells were investigated.

Further (Ac)(5)GP also exerted an inhibitory effect on phosphoinositide 3-kinase (PI3K) protein expression, phosphorylation of extracellular signal-regulated kinases 1 and 2 (ERK1/2) and inhibition of activation of transcription factor nuclear factor kappa B (NF-kappaB), c-Fos, c-Jun.

Findings suggest (Ac)(5)GP is highly likely to be an inhibiting cancer migration agent to be further developed in the future (Huang et al., 2009).

Melanoma

A new iridoid glycoside, 10-O-(4'-O-methylsuccinoyl) geniposide, and two new pyronane glycosides, jasminosides Q and R, along with nine known iridoid glycosides, and two known pyronane glycosides, were isolated from a MeOH extract of Gardeniae Fructus, the dried ripe fruit of Gardenia jasminoides (Rubiaceae).

The structures of new compounds were elucidated on the basis of extensive spectroscopic analyzes and comparison with literature. Upon evaluation of these compounds on the melanogenesis in B16 melanoma cells induced with α-melanocyte-stimulating hormone (α-MSH), three compounds, i.e., 6-O-p-coumaroylgeniposide (3), 7, and 6'-O-sinapoyljasminoside (12), exhibited inhibitory effects with 21.6-41.0 and 37.5-47.7% reduction of melanin content at 30 and 50 µM, respectively, with almost no toxicity to the cells (83.7-106.1% of cell viability at 50 µM) (Akisha et al., 2012).

Hepatoma, Prostate Cancer, Cervical Cancer

Genipin is a metabolite of geniposide isolated from an extract of Gardenia fructus. Some observations suggested that genipin could induce cell apoptosis in hepatoma cells and PC3 human prostate cancer cells. Genipin could remarkably induce cytotoxicity in HeLa cells and inhibit its proliferation. Induction of the apoptosis by genipin was confirmed by analysis of DNA fragmentation and induction of sub-G(1) peak through flow cytometry.

The results also showed that genipin-treated HeLa cells cycle was arrested at G(1) phase. Western blot analysis revealed that the phosphorylated c-Jun NH(2)-terminal kinase (JNK) protein, phospho-Jun protein, p53 protein and bax protein significantly increased in a dose-dependent manner after treatment of genipin for 24 hours; the activation of JNK may result in the increase of the p53 protein level; the increase of the p53 protein led to the accumulation of bax protein; and bax protein further induced cell apoptotic death eventually (Cao et al., 2010).

Angelicin

Cancer: Leukemia, colon, ER+ Ovarian

Action: Apoptotic, anti-cancer

Angelicin is a furanocoumarin. It can be found in Bituminaria bituminosa and is structurally related to psoralens, a well-known chemical class of photosensitizers used for its anti-proliferative activity in treatment of different skin diseases.

Induces Apoptosis

The cellular cytotoxicity of angelicin was examined by cell viability assay, DNA fragmentation by DNA ladder assay, and activation of caspases and Bcl-2 family proteins by Western blot analyzes. The results suggest that angelicin increased cellular cytotoxicity in a dose- and time-dependent manner with IC(50) of 49.56 µM at 48 hours of incubation.

In addition, angelicin dose-dependently downregulated the expression of anti-apoptotic proteins including Bcl-2, Bcl-xL, and Mcl-1 suggesting the involvement of the intrinsic mitochondria-mediated apoptotic pathway which did not participate in Fas/FasL-induced caspase-8-mediated extrinsic, MAP kinases, and PI3K/AKT/GSK-3β pathway.

Taken together, these data indicate that angelicin is an effective apoptosis-inducing natural compound of human SH-SY5Y neuroblastoma cells which suggests that this compound may have a role in future therapies for human neuroblastoma cancer (Rahman et al., 2012).

Anti-cancer

Three crude drugs Saussureae Radix, Psoraleae Semen and Aurantti Fructus Immaturus significantly inhibited the proliferation of temperature-sensitive rat lymphatic endothelial (TR-LE) cells in vitro. Angelicin isolated from Aurantti Fructus Immaturus showed selective inhibition of the proliferation of TR-LE cells (Jeong et al., 2013). Angelicin, isolated from Bituminaria morisiana was subjected to cytotoxicity screening against a panel of human cancer cells (Leonti et al., 2010).

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).

Millettia reticulata flavonoids

(-)-epicatechin, naringenin, 5,7,3′,5′-tetrahydroxyflavanone, formononetin, isoliquiritigenin, and genistein

Action: Induces apoptosis

A study by Fang, Hsu, Lin & Yen (2010) was done on the vitro anticancer activity of flavonoid derivatives isolated from the stems of M. reticulata Benth. Six flavonoid derivatives including (-)-epicatechin (1), naringenin (2), 5,7,3′,5′-tetrahydroxyflavanone (3), formononetin (4), isoliquiritigenin (5), and genistein (6) were isolated from the stems of M. reticulata Benth.

The structures of 1-6 were determined by spectroscopic methods. The effects of flavonoid derivatives (1-6) on the viability of human cancer cells (including HepG2, SK-Hep-1, Huh7, PLC5, COLO 205, HT-29, and SW 872 cells) were investigated. The results indicated that genistein (6) had the strongest inhibitory activity with an IC(50) value of 16.23 microM in SK-Hep-1 human hepatocellular carcinoma cells. Treatment of SK-Hep-1 cells with genistein (6) caused loss of mitochondrial membrane potential. Western blot data revealed that genistein (6) stimulated an increase in the protein expression of Fas, FasL, and p53. Additionally, treatment with genistein (6) changed the ratio of expression levels of pro- and anti-apoptotic Bcl-2 family members and subsequently induced the activation of caspase-9 and caspase-3, which was followed by cleavage of poly(ADP-ribose) polymerase (PARP). These results demonstrate that genistein (6) induces apoptosis in SK-Hep-1 cells via both Fas- and mitochondria-mediated pathways.
