Gypenosides

Cancer: Leukemia, colorectal., oral., esophageal

Action: Apoptosis,inhibits cell proliferation and migration

Gypenosides (Gyp), found in Gynostemma pentaphyllum Makino [(Thunb) Makino], have been used as folk medicine for centuries and have exhibited diverse pharmacological effects, including anti-leukemia effects in vitro and in vivo.

Gyp have been used to examine effects on cell viability, cell-cycle, and induction of apoptosis in vitro. They were administered in the diet to mice injected with WEHI-3 cells in vivo. Gyp inhibited the growth of WEHI-3 cells. These effects were associated with the induction of G0/G1 arrest, morphological changes, DNA fragmentation, and increased sub-G1 phase. Gyp promoted the production of reactive oxygen species, increased Ca2+ levels, and induced the depolarization of the mitochondrial membrane potential.

The effects of Gyp were dose- and time-dependent. Moreover, Gyp increased levels of the pro-apoptotic protein Bax, reduced levels of the anti-apoptotic proteins Bcl-2, and stimulated release of cytochrome c, AIF (apoptosis-inducing factor), and Endo G (endonuclease G) from mitochondria. The levels of GADD153, GRP78, ATF6-α, and ATF4-α were increased by Gyp, resulting in ER (endoplasmic reticular) stress in WEHI-3 cells. Oral consumption of Gyp increased the survival rate of mice injected with WEHI-3 cells used as a mouse model of leukemia.

Results of these experiments provide new information on understanding mechanisms of Gyp-induced effects on cell-cycle arrest and apoptosis in vitro and in an in vivo animal model (Hsu et al., 2011).

Inhibits Cell Proliferation and Migration

Results indicated that Gypenosides (Gyp) inhibited cell proliferation and migration in SW620 and Eca-109 cells in dose- and time-dependent manner. Gyp elevated intracellular ROS level, decreased the Δψ m, and induced apoptotic morphology such as cell shrinkage and chromatin condensation, suggesting oxidative stress and mitochondria-dependent cell apoptosis that might be involved in Gyp-induced cell viability loss in SW620 and Eca-109 cells. The findings indicate Gyp may have valuable application in clinical colon cancer and esophageal cancer treatments (Yan et al., 2013).

Gyp-induced cell death occurs through caspase-dependent and caspase-independent apoptotic signaling pathways, and the compound reduced tumor size in a xenograft nu/nu mouse model of oral cancer.

Gyp induced morphological changes, decreased the percentage of viable cells, caused G0/G1 phase arrest, and triggered apoptotic cell death in SAS cells. Cell-cycle arrest induced by Gyp was associated with apoptosis. The production of ROS, increased intracellular Ca(2+) levels, and the depolarization of ΔΨ(m) were observed. Gyp increased levels of the pro-apoptotic protein Bax but inhibited the levels of the anti-apoptotic proteins Bcl-2 and Bcl-xl. Gyp also stimulated the release of cytochrome c and Endo G. Translocation of GADD153 to the nucleus was stimulated by Gyp. Gyp in vivo attenuated the size and volume of solid tumors in a murine xenograft model of oral cancer (Lu et al., 2012).

Cell-cycle Arrest

Lin et al. (2011) have shown that gypenosides (Gyp) induced cell-cycle arrest and apoptosis in many human cancer cell lines. In the present study the effects of Gyp on cell morphological changes and viability, cell-cycle arrest and induction of apoptosis in vitro and effects on Gyp in an in vivo murine xenograft model were demonstrated. Results indicated that Gyp induced morphological changes, decreased cell viability, induced G0/G1 arrest, DNA fragmentation and apoptosis (sub-G1 phase) in HL-60 cells. Gyp increased reactive oxygen species production and Ca(2+) levels but reduced mitochondrial membrane potential in a dose- and time-dependent manner.

Oral consumption of Gyp reduced tumor size of HL-60 cell xenograft mode mice in vivo. These results provide new information on understanding mechanisms by which Gyp induces cell-cycle arrest and apoptosis in vitro and in vivo (Lin et al., 2011).

Artesunate

Cancer: Colon, esophageal., pancreatic, ovarian, multiple myeloma and diffuse large B-cell lymphoma, osteosarcoma, lung, breast, skin, leukemia/lymphoma

Action: Anti-metastatic, MDR, radio-sensitizer

Pulmonary Adenocarcinomas

Artesunate exerts anti-proliferative effects in pulmonary adenocarcinomas. It mediates these anti-neoplastic effects by virtue of activating Bak (Zhou et al., 2012). At the same time, it down-regulates epidermal growth factor receptor expression. This results in augmented non-caspase dependent apoptosis in the adenocarcinoma cells. Artesunate mediated apoptosis is time as well as dose-dependent. Interestingly, AIF and Bim play significant roles in this Bak-dependent accentuated apoptosis (Ma et al., 2011). Adenosine triphosphate (ATP)-binding cassette subfamily G member 2 (ABCG2) expression is also attenuated while transcription of matrix metallopeptidase 7 (MMP-7) is also down-regulated (Zhao et al., 2011). In addition, arsenuate enhances the radio-sensitization of lung carcinoma cells. It mediates this effect by down-regulating cyclin B1 expression, resulting in augmented G2/M phase arrest (Rasheed et al., 2010).

Breast Cancer

Similarly, artesunate exhibits anti-neoplastic effects in breast carcinomas. Artesunate administration is typically accompanied by attenuated turnover as well as accentuated peri-nuclear localization of autophagosomes in the breast carcinoma cells. Mitochondrial outer membrane permeability is typically augmented. As a result, artesunate augments programmed cellular decline in breast carcinoma cells (Hamacher-Brady et al., 2011).

Skin Cancer

Artesunate also exerts anti-neoplastic effects in skin malignancies. It mediates these effects by up-regulating p21. At the same time it down-regulates cyclin D1 (Jiang et al., 2012).

Colon Cancer

Artemisunate significantly inhibited both the invasiveness and anchorage independence of colon cancer SW620 cells in a dose-dependent manner. The protein level of intercellular adhesion molecule 1 (ICAM-1) was down-regulated as relative to the control group.

Artemisunate could potentially inhibit invasion of the colon carcinoma cell line SW620 by down-regulating ICAM-1 expression (Fan, Zhang, Yao & Li, 2008).

Multi-drug resistance; Colon Cancer

A profound cytotoxic action of the antimalarial., artesunate (ART), was identified against 55 cancer cell lines of the U.S. National Cancer Institute (NCI). The 50% inhibition concentrations (IC50 values) for ART correlated significantly to the cell doubling times (P = 0.00132) and the portion of cells in the G0/G1 (P = 0.02244) or S cell-cycle phases (P = 0.03567).

Efferth et al., (2003) selected mRNA expression data of 465 genes obtained by microarray hybridization from the NCI data-base. These genes belong to different biological categories (drug resistance genes, DNA damage response and repair genes, oncogenes and tumor suppressor genes, apoptosis-regulating genes, proliferation-associated genes, and cytokines and cytokine-associated genes). The constitutive expression of 54 of 465 (=12%) genes correlated significantly to the IC50 values for ART. Hierarchical cluster analysis of these 12 genes allowed the differentiation of clusters with ART-sensitive or ART-resistant cell lines (P = 0.00017).

Multi-drug-resistant cells differentially expressing the MDR1, MRP1, or BCRP genes were not cross-resistant to ART. ART acts via p53-dependent and- independent pathways in isogenic p53+/+ p21WAF1/CIP1+/+, p53-/- p21WAF1/CIP1+/+, and p53+/+ p21WAF1/CIP1-/- colon carcinoma cells.

Multi-drug resistance; Esophageal Cancer

The present study aimed to investigate the correlation between ABCG2 expression and the MDR of esophageal cancer and to estimate the therapeutic benefit of down-regulating ABCG2 expression and reversing chemoresistance in esophageal cells using artesunate (ART).

ART is a noteworthy antimalarial agent, particularly in severe and drug-resistant cancer cases, as ART is able to reverse drug resistance. ART exerted profound anti-cancer activity. The mechanism for the reversal of multi-drug resistance by ART in esophageal carcinoma was analyzed using cellular experiments, but still remains largely unknown (Liu, Zuo, & Guo, 2013).

Pancreatic Cancer

The combination of triptolide and artesunate could inhibit pancreatic cancer cell line growth, and induce apoptosis, accompanied by expression of HSP 20 and HSP 27, indicating important roles in the synergic effects. Moreover, tumor growth was decreased with triptolide and artesunate synergy. Results indicated that triptolide and artesunate in combination at low concentrations can exert synergistic anti-tumor effects in pancreatic cancer cells with potential clinical applications (Liu & Cui, 2013).

Ovarian Cancer

Advanced-stage ovarian cancer (OVCA) has a unifocal origin in the pelvis. Molecular pathways associated with extrapelvic OVCA spread are also associated with metastasis from other human cancers and with overall patient survival. Such pathways represent appealing therapeutic targets for patients with metastatic disease.

Pelvic and extrapelvic OVCA implants demonstrated similar patterns of signaling pathway expression and identical p53 mutations.

However, Marchion et al. (2013) identified 3 molecular pathways/cellular processes that were differentially expressed between pelvic and extrapelvic OVCA samples and between primary/early-stage and metastatic/advanced or recurrent ovarian, oral., and prostate cancers. Furthermore, their expression was associated with overall survival from ovarian cancer (P = .006), colon cancer (1 pathway at P = .005), and leukemia (P = .05). Artesunate-induced TGF-WNT pathway inhibition impaired OVCA cell migration.

Multiple Myeloma, B-cell Lymphoma

Findings indicate that artesunate is a potential drug for treatment of multiple myeloma and diffuse large B-cell lymphoma (DLBCL) at doses of the same order as currently in use for treatment of malaria without serious adverse effects. Artesunate treatment efficiently inhibited cell growth and induced apoptosis in cell lines. Apoptosis was induced concomitantly with down-regulation of MYC and anti-apoptotic Bcl-2 family proteins, as well as with cleavage of caspase-3. The IC50 values of artesunate in cell lines varied between 0.3 and 16.6 µm. Furthermore, some primary myeloma cells were also sensitive to artesunate at doses around 10 µm. Concentrations of this order are pharmacologically relevant as they can be obtained in plasma after intravenous administration of artesunate for malaria treatment (Holien et al., 2013).

Osteosarcoma, Leukemia/Lymphoma

Artesunate inhibits growth and induces apoptosis in human osteosarcoma HOS cell line in vitro and in vivo (Xu et al. 2011). ART alone or combined with chemotherapy drugs could inhibit the proliferation of B/T lymphocytic tumor cell lines as well ALL primary cells in vitro, probably through the mechanism of apoptosis, which suggest that ART is likely to be a potential drug in the treatment of leukemia/lymphoma (Zeng et al., 2009).

Artesunate, oral (See also Injectables)

Cancer:
Non-resectable tumors, Retinoblastoma, colon, esophageal., retinoblastoma, ovarian, lung, glioblastoma, MDR, gastric

Action: Anti-cancer

Artesunate is a semisynthetic derivative of the herbal anti-malaria drug artemisinin, which is the active agent from Artemisia annua L. used in traditional Chinese medicine.

Anti-cancer; Canine

The anti-malarial drug artesunate has shown anti-cancer activity in vitro and in preliminary animal experiments, but experience in patients with cancer is very limited. Preclinical studies in dogs indicated morbidity at high dosage levels. The effects of artesunate have been examined in canine cancer cell lines and in canine cancer patients. A safety/efficacy field study with artesunate was conducted in 23 dogs with non-resectable tumors.

Artesunate was administered for 7–385 days at a dosage of 651-1178 (median 922) mg/m(2). No neurological or cardiac toxicity was observed and seven dogs exhibited no adverse effects at all. Fever and haematological/gastrointestinal toxicity, mostly transient, occurred in 16 dogs. Plasma artesunate and DHA levels fell below the limit of detection within 8–12 hours after artesunate administration, while levels after two hours were close to 1 µM. Artesunate produced a long-lasting complete remission in one case of cancer and short-term stabilization of another 7 cases. This study suggests artesunate may be an effective anti-cancer agent in humans (Rutteman, 2013).

Lung Cancer

The exact molecular mechanism by which artesunate induces apoptosis in human lung adenocarcinoma (ASTC-a-1 and A549) cell lines has been examined, and it was found that artesunate induces apoptosis via a Bak-mediated caspase-independent intrinsic pathway in human lung adenocarcinoma cells. Artesunate treatment was found to induce ROS-mediated apoptosis in a concentration- and time-dependent fashion accompanying the loss of mitochondrial potential and subsequent release of Smac and AIF indicative of intrinsic apoptosis pathway. Furthermore, although ART treatment did not induce a significant down-regulation of voltage-dependent anion channel 2 (VDAC2) expression and up-regulation of Bim expression, silencing VDAC2 potently enhanced the artesunate-induced Bak activation and apoptosis which were significantly prevented by silencing Bim.

Collectively, our data firstly demonstrate that artesunate induces Bak-mediated caspase-independent intrinsic apoptosis in which Bim and VDAC2 as well as AIF play important roles in both ASTC-a-1 and A549 cell lines, indicating a potential therapeutic effect of artesunate for lung cancer (Zhou, 2012).

Glioblastoma

Trials that include artesunate in cancer therapy are ongoing due to its action as a powerful inducer of oxidative DNA damage, giving rise to formamidopyrimidine DNA glycosylase-sensitive sites and the formation of 8-oxoguanine and 1,N6-ethenoadenine. Oxidative DNA damage was induced in LN-229 human glioblastoma cells dose-dependently and was paralleled by cell death executed by apoptosis and necrosis, which could be attenuated by radical scavengers such as N-acetyl cysteine.

These data indicate that both homologous recombination and nonhomologous end joining are involved in the repair of artesunate-induced DNA double-strand break (DSB). Artesunate provoked a DNA damage response (DDR) with phosphorylation of ATM, ATR, Chk1, and Chk2.

Overall, these data revealed that artesunate induces oxidative DNA lesions and DSB that continuously increase during the treatment period and accumulate until they trigger discoidin domain receptors (DDR) and finally tumor cell death (Berdelle, 2011).

Esophageal Cancer, MDR

The Eca109/ABCG2 cell line was established by transfecting the ABCG2 gene into Eca109 cells. The Eca109/ABCG2 esophageal cancer cells with ABCG2 gene overexpression were resistant to adriamycin (ADM), daunorubicin (DNR) and mitoxantrone (MIT), which indicated that ABCG2 may be associated with drug resistance in esophageal cancer.

Artesunate (ART) exerted profound anti-cancer activity. The mechanism for the reversal of multi-drug resistance by Art in esophageal carcinoma was analyzed using cellular experiments (Liu, Zuo, & Guo, 2013).

Artesunate was found to stop the growth of esophageal cancer cells transplated subcutaneous tumors in nude mice in the G1 stage. It is hence thought that the role of Artesunate against esophageal carcinoma maybe relate to cell-cycle blockage. Artesunate was also found to increase the expression of SMAD3 and TGF-β1, and reduce the expression of CDC25A and CDC25B which may also play a role in its anti-cancer activity.

Retinoblastoma

Zhao et al. (2013) found that the cytotoxic action of artesunate (ART) is specific for Retinoblastoma (RB) cells in a dose-dependent manner, with low toxicity in normal retina cells. ART is more effective in RB than carboplatin with a markedly strong cytotoxic effect on carboplatin-resistant RB cells. RB had higher CD71 levels at the membrane compared to normal retinal cells. ART is a promising drug exhibiting high selective cytotoxicity even against multi-drug-resistant RB cells.

Gastric Cancer

Artesunate has concentration-dependent inhibitory activities against gastric cancer in vitro and in vivo by promoting cell oncosis through an impact of calcium, vascular endothelial growth factor, and calpain-2 expression (Zhou et al., 2013).

Ovarian Cancer

Advanced-stage ovarian cancer (OVCA) has a unifocal origin in the pelvis. Molecular pathways associated with extrapelvic OVCA spread are also associated with metastasis from other human cancers and with overall patient survival. Such pathways represent appealing therapeutic targets for patients with metastatic disease. Artesunate-induced TGF-WNT pathway inhibition impaired OVCA cell migration (Marchion et al., 2013).

Colon Cancer

After colon cancer SW620 cells were treated with different doses of Artemisunate, anchorage independence was studied in soft agar colony formation. Invasiveness was assessed by Boyden chamber, and the protein level of intercellular adhesion molecule-1 (ICAM-1) was detected by Western blot assay. Artemisunate significantly inhibited both the invasiveness and anchorage independence in a dose-dependent manner. The protein level of ICAM-1 was down-regulated as relative to the control group.

Artemisunate could potentially inhibit invasion of the colon carcinoma cell line SW620 by down-regulating ICAM-1 expression (Fan, Zhang, Yao, & Li, 2008).
