Abstract
Medicinal plants are considered to be a critical source of novel compounds and pharmacophores. The genus Ardisia, consisting of approximately 500 species, is the largest genus in the Myrsinaceae family. Ardisia species are widely distributed throughout tropical and subtropical regions of the world and have been used for the treatment of cancer, hypertension, irregular menstruation, gonorrhea, diarrhea and postnatal syndromes, among others. Phytochemical studies of Ardisia species have resulted in the isolation and identification of 111 compounds, including triterpenoid saponins, quinones, phenols, coumarins, cyclic depsipepetide and flavonoids. Crude extracts and isolates from Ardisia have been reported to have in vitro and in vivo efficacies, including but not limited to anticancer, antiinflammatory, antimicrobial, antioxidant, antithrombotic and antidiabetic, antitubercular compounds. This review focuses on the medical and functional uses, phytochemical profile and pharmacological efficacies of Ardisia species over the past 15 years. This review will provide information indicating that Ardisia species represent an invaluable source of potential therapeutic compounds.

Abstract
Seventeen 13,28-epoxy triterpenoid saponins obtained from Ardisia gigantifolia STAPF. were evaluated their anti-proliferative activities on MCF-7 cells. The structure-activity relationship analysis indicated that CH3 group at C-30, four saccharide units with L-rhamnose at R6 in the sugar units are crucial for the cytotoxic activity on MCF-7. Compounds 1, 2, 6, 7, 12, and 14 were selected to identify the anti-proliferative activity on the other three breast cancer cell lines (T47D, MDA-MB-231 and SK-BR-3). Compounds 2, 6, and 7 with good activity on MCF-7 also showed activity on T47D, MDA-MB-231, and SK-BR-3. Compounds 12 and 14 without cytotoxic activity on MCF-7 almost showed no activities on the other three cell lines. For the triple-negative breast cancer MDA-MB-231, Saponins 7 and 14 showed selective cytotoxic activity, 7 showed much more activity than 14, suggesting the six saccharide units in sugar units and CH3 on C-30 were the key moieties for the anti-proliferative activities. Further molecular mechanism of saponin 7 was studied on inhibiting cell proliferation of MDA-MB-231 cells. Saponin 7 could enhance apoptosis, arrest cell cycles, decrease mitochondrial membrane potentials (MMPs), and considered the involvement of reactive oxygen species (ROS) may explain this conundrum.

Abstract
Background Ardipusilloside-I (ADS-I) is a triterpenoid saponin extracted from Chinese medicinal herb Ardisiapusill A. DC. Previous studies have demonstrated the potent anti-tumor activities of ADS-I both in vitro and in vivo, and its main metabolites (M1 and M2) from human intestinal bacteria. However, the physicochemical properties and intestinal permeation rate of ADS-I and its metabolites are not understood. In this study, the octanol/water distribution coefficients (logP) of ADS-I and metabolites were investigated using standard shake flask technique, and their permeability properties was investigated across Caco-2 cells monolayer. Results The logP of ADS-I, M1 and M2 was −0.01, 0.95 ± 0.04, 1.57 ± 0.11, respectively. The Papp values of ADS-I, M1 and M2 (in 10 μmol/L) across Caco-2 cell monolayers from the apical (AP) to basolateral (BL) direction were 1.88 ± 0.21 × 10−6 cm·s−1, 4.30 ± 0.43 × 10−6 cm·s−1, 4.74 ± 0.47 × 10−6 cm·s−1, respectively. Conclusion Our data indicated that ADS-I has the poorer intestinal absorption than its metabolites (M1 and M2) in these experimental systems, suggesting that the metabolites of ADS-I may be the predominant products absorbed by the intestine when ADS-I is administered orally.

AG4, a compound isolated from Radix Ardisiae Gigantifoliae, induces apoptosis in human nasopharyngeal cancer CNE cells through intrinsic and extrinsic apoptosis pathways. Anticancer Drugs 2015; 26:331-42.

Abstract
3β-O-{α-L-Pyran rhamnose-(1→3)-[β-D-xylopyranose-(1→2)]-β-D-glucopyranose-(1→4)-[β-D-lucopyranose-(1→2)]-α-L-pyran arabinose}-cyclamiretin A (AG4) is a saponin component obtained from the Giantleaf Ardisia Rhizome (Rhizoma Ardisiae Gigantifoliae). The present study aimed to investigate the antitumor potential of AG4 and its possible mechanisms in human nasopharyngeal carcinoma cells (CNE). We exposed tumor cells to AG4 to investigate which cell line was the most sensitive to AG4. Cell viability was assessed using the MTT reduction assay, and the effects of AG4 on apoptosis, reactive oxygen species (ROS) content, mitochondrial membrane potential (MMP), and cell cycle were detected using a flow cytometer; the glutathione, superoxide dismutase and malondialdehyde activities were measured using colorimetric methods. The relative expressions of Bax, Bad, Bid, Bcl-2, and Fas mRNA were calculated using the (Equation is included in full-text article.)comparative method by real-time PCR studies and protein was detected by western blotting. AG4 markedly inhibited the growth of CNE cells by decreasing cell proliferation, inducing apoptosis, and blocking the cell cycle in the S phase. The release of caspase-3, caspase-8, and caspase-9 was stimulated by AG4 in CNE, and the decreased proliferation induced by AG4 was blocked by the inhibitor of pan caspase (Z-VAD-FMK). Moreover, the MMP was decreased in AG4-treated cells, and AG4-induced cell apoptosis was accompanied by a rapid and lasting increase in ROS, which was abolished by N-acetyl-L-cysteine (NAC); glutathione, superoxide dismutase, and malondialdehyde were regulated by AG4. AG4 inhibited Bcl-2 mRNA and protein expression and stimulated Bax, Bad, Bid, Fas mRNA, and protein expression in CNE cultures, suggesting an effect at the transcriptional and protein level. In addition, both the FasL inhibitor (AF-016) and the Bcl-2 family inhibitor (GX15-070) could prevent the cell apoptosis induced by AG4. The findings suggested that AG4-induced apoptosis in CNE cells involved a death receptor pathway and a Bcl-2 family-mediated mitochondrial signaling pathway by decreasing the MMPs in an ROS-dependent manner and regulating genes and proteins relative to apoptosis; also, regulation of cell cycles may also play a role in the antitumor mechanism of AG4.

Abstract
As a part of our ongoing studies on cytotoxic triterpenoid saponins from herbal medicines, phytochemical investigation of the roots of Bupleurum chinense DC. afforded four new saikosaponins (1-4), along with 16 known ones (5-20). Their structures were established by direct interpretation of their spectral data, mainly HR-ESI-MS, 1D NMR and 2D NMR, and by comparison with literature data. Among them, compound 20 was isolated from the natural product for the first time. The cytotoxicities of all compounds against five selected human cancer cell lines (A549, HepG2, Hep3B, Bcap-37 and MCF-7) were assayed. In general, a number of the isolated compounds exhibited potent cytotoxic activities against the five selected human cancer cell lines. In particular, compounds 3, 8-9, 11-13, 16 and 20 showed more potent cytotoxic activities against the HepG2 and A549 cell lines than the positive control 5-fluorouracil. Based on the primary screening results, the preliminary structure-activity relationship (SAR) studies were also discussed. The SAR results suggest that the 13,28-epoxy bridge, the orientation of the hydroxyl group and the type of the sugar units are important requirements for cytotoxicity and selectivity.

Abstract
AIMS Ardipusilloside I (ADS-I), a triterpenoid saponin isolated from Ardisia pusilla A.DC (Myrsinaceae), has been recently tested for cancer treatment including brain cancer. However, the mechanism of its action remains elusive. The present study was to investigate the role of autophagy activation in the anti-tumor activities of ADS-I in human glioma cells. MAIN METHODS The tetrazolium dye (MTT) colorimetric assay was used for the measurement of cell proliferation in cultured glioma cells, transmission electron microscopy (TEM) for the examination of autophagic activity, flow cytometric analysis for the determination of cell cycle and apoptotic cells, and immunocytochemistry and Western blot for protein expression of microtubule-associated protein light-chain 3 (LC3) and Beclin 1. KEY FINDINGS ADS-I significantly inhibited the proliferation of both U373 and T98G glioma cells in cultures in a dose-dependent manner. The cytotoxic activity of ADS-I against glioma cell growth was associated not only with the induction of cell cycle arrest at G2/M phase and cell apoptosis in flow cytometric analysis, but also with the activation of autophagy, indicated by the formation of autophagosomes and up-regulated expression of both autophagic protein Beclin 1 and LC3 in glioma cells. Additionally, the treatment with chloroquine, an autophagy inhibitor, reduced ADS-1-mediated cell death. SIGNIFICANCE These data suggest that the anti-proliferative activity of ADS-I in human glioma cells is associated with the activation of autophagy in addition to cell cycle arrest and apoptosis, and the antagonistic effect of chloroquine suggests an important role of autophagy in ADS-I-mediated cell death against tumor growth.

Abstract
Background Ardisia pusilla A. DC., family Myrsinaceae, is a traditional Chinese medicine named Jiu Jie Long with a variety of pharmacological functions including anti-cancer activities. In this study, we purified a natural triterpenoid saponin, ardipusilloside I, from Ardisia pusilla, and show that it exhibits inhibitory activities in human mucoepidermoid carcinoma Mc3 cells. We also investigated the underlying mechanisms of proliferation inhibition that ardipusilloside I exerts on Mc3 cells. Methods MTT test was used to detect cell proliferation. Cell apoptosis was detected by transmission electron microscopy, Hoechst-33342 staining, DNA fragmentation detection, and flow cytometry. We also used western blot analysis to detect the potential mechanisms of apoptosis. Results Ardipusilloside I affected the viability of Mc3 cells in a dose- and time-dependent manner. The IC50 of ardipusilloside I was approximately 9.98 μg/ml at 48 h of treatment. Characteristic morphological changes of apoptosis, including nuclear condensation, boundary aggregation and splitting, and DNA fragmentation, were seen after treatment with 10 μg/ml ardipusilloside I for 48 h. Western blots demonstrated that ardipusilloside I caused Mc3 cell death through the induction of apoptosis by downregulation of Bcl-2 protein levels and upregulation of Bax and caspase-3 protein levels. Conclusions Our results revealed that ardipusilloside I could be a new active substance for mucoepidermoid carcinoma treatment. We demonstrated that the potential mechanism of inhibition might be through the induction of apoptosis by regulation of Bcl-2 family protein levels. This suggests a further rationale for the development of ardipusilloside I as an anti-cancer agent.

Abstract
The 30-amino acid antimicrobial peptide Cbf-K16 is a cathelicidin-BF (BF-30) Lys16 mutant derived from the snake venom of Bungarus fasciatus. Our previous study found that BF-30 selectively inhibited the proliferation of the metastatic melanoma cell line B16F10 in vitro and in vivo, but had a negligible effect on human lung cells. In the present study, it was demonstrated for the first time that Cbf-K16 selectively inhibits the proliferation of lung carcinoma cells in vitro, with low toxicity to normal cells. The half-maximal inhibitory concentrations (IC50) of Cbf-K16 against H460 human non-small cell lung carcinoma cells and mouse Lewis lung cancer cells were only 16.5 and 10.5 µM, respectively, which were much less compared to that of BF-30 (45 and 40.3 µM). Data using a transmission electron microscope (TEM) assay showed that, at 20 and 40 µM, Cbf-K16 induced the rupture of the cytoplasmic membrane, which was consistent with data obtained from lactate dehydrogenase (LDH) release assays. The LDH release increased from 17.8 to 52.9% as the duration and dosage of Cbf-K16 increased. Annexin V-fluorescein and propidium iodide staining assays indicated that there were no obvious apoptotic effects at the different dosages and times tested. In H460 cells, the rate of genomic DNA binding increased from 51.9 to 86.8% as the concentration of Cbf-K16 increased from 5 to 10 µM. These data indicate that Cbf-K16 selectively inhibits the proliferation of lung carcinoma cells via cytoplasmic membrane permeabilization and DNA binding, rather than apoptosis. Although Cbf-K16 displayed significant cytotoxic activity (40 µM) against tumor cells, in splenocytes no significant inhibitory effect was observed and hemolysis was only 5.6%. These results suggest that Cbf-K16 is a low-toxicity anti-lung cancer drug candidate.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ardipusilloside I is a triterpene-saponin isolated from the Traditional Chinese Medicine Ardisia pusilla A. DC. Its effects and mechanism on invasion and metastasis of liver cancer cells are unclear. MATERIALS AND METHODS The human hepatocellular carcinoma cell line HepG2 and SMMC-7721 cells were treated with different doses of Ardipusilloside I. Cellular survival, in vitro migration and invasion were evaluated. In vivo metastatic abilities of the HCC cells were detected. We further investigated expression and phosphorylation of Mek, Erk and Akt by using Western blot. MMP2 and MMP9 activities were evaluated by gelatin zymography. E-cadherin expression, Rac1 and Cdc42 activities were examined by Western blot and pull-down assay. RESULTS Ardipusilloside I inhibited invasion and metastasis of HCC cells both in vitro and in vivo by reducing the protein expressions of metalloproteinase (MMP)-9 and MMP2 proteins. Ardipusilloside I activated Rac1 that enhanced E-cadherin activity and resulted in significantly less metastasis. CONCLUSION Our findings indicate that Ardipusilloside I has the potential of inhibition of liver cancer survival, invasion and metastasis both in vitro and in vivo.

Abstract
Ardisia species (Myrsinaceae) are found throughout tropical and subtropical regions of the world. Traditional medicinal uses attributed to Ardisia include alleviation of liver cancer, swelling, rheumatism, earache, cough, fever, diarrhea, broken bones, dysmenorrhea, respiratory tract infections, traumatic injuries, inflammation, pain, snake and insect bites, birth complications and to improve general blood circulation, among others. Ardisia species are rich in polyphenols, triterpenoid saponins, isocoumarins, quinones and alkylphenols. A summary of the uses, potential health benefits, adverse reactions and important bioactive phytochemicals isolated from the Ardisia species is presented. Future research needs to include more toxicological studies, more comprehensive chemical characterization of extracts, bioavailability, extract standardization, investigation of possible herb-drug interactions, plant improvement with regards to bioactivity and composition, and additional human and animal studies to confirm the health-promoting properties claimed for Ardisia species. The information presented here exemplifies the potential of Ardisia species as a source of chemotherapeutic, chemo-modulating and/or chemopreventive agents.

Abstract
The aim of this study was to evaluate the effects of ardipusilloside I isolated from Ardisia pusilla on tumor angiogenesis and its mechanism of action. The anti-angiogenic effect in vivo was evaluated on xenograft in the athymic mice model and the chicken chorioallantoic membrane (CAM) neovascularization model, the inhibition of growth in vitro was detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, and the mechanism was demonstrated through detecting microvessel density (MVD), vascular endothelial growth factor (VEGF), VEGF receptor 2 (VEGFR2) and P-VEGFR2 protein expressions, as well as mRNA expressions of VEGF and VEGFR2. The results showed that ardipusilloside I had a good inhibitory effect on A549 xenografted tumor growth, angiogenesis of CAM, and A549 cell growth. Compared to the negative control, MVD protein and mRNA expressions of VEGF and VEGFR were significantly inhibited by ardipusilloside I in a dose-dependent manner. These findings suggested that ardipusilloside I might be a promising candidate as angiogenesis inhibitors.
