Marine algae is known to contain a wide variety of biomedical compounds having pharmaceutical applications. The aim of this research was to evaluate cytotoxic activity and apoptosis induction of Turbinaria decurrens extract on T47D cell lines.  Cytotoxic activity test was conducted by using MTT assay whereas detection of apoptosis was evaluated by DNA fragmentations and flow cytometry analysis. The MTT test showed that crude extract had medium cytotoxic activity to T47D, HepG2, and C28 cell lines with IC50 value of 172, againts 360 and 330 µg ml-1, respectively. After solvent partition of crude extract, the cytotoxic activity of n-hexane and ethyl acetate fractions T47D cell increased, the cytotoxic activity of n. hexane and ethyl acetate fractions T47D cell increased with  IC50  value of with IC50  43.1 and 51.9 µg ml-1, respectively, whereas IC50 value of methanol fraction was 383.0 µg ml-1. Analysis of DNA fragmentation of T47D cell showed that  both n-hexane and ethyl acetate fractions could not fragment DNA as a features of apoptosis. However, flow cytometry analysis by using annexin-V and propidium iodide staining revealed that n-hexane and ethyl acetate fractions could induce apoptosis in T47D cell. This research indicated that Turbinaria decurrens had potency to induce apoptosis in T47D cells.

Research into plants with anticancer effects is actively encouraged in orderto discover new drugs with lessertoxicity but more potent effects. The aims of study are to evaluate the antioxidant properties and to investigate the cytotoxic activity of Plectranthus amboinicus (Lour.) Spreng. leaves ethyl acetate fractions on HeLa,T47D and MCF7 cell lines. The extract was prepared by graded maceration using n-hexane and ethyl acetate. The ethyl acetate extract was fractionated in vacuum liquid chromatography with n-hexane: ethyl acetate; and ethyl acetate: methanol as mobile phase. Then, the fractions were analyzed with thin layer chromatography (TLC). The free radical scavenging activity was measured by DPPH method, the total flavonoid content was calculated by quercetin equivalent and the absorbance is measured by using UV-Visible spectrophotometry. The cytotoxic activity were determined using MTT assay. The fractions contained 5 sub fractions with same TLC profile. The fractions showed antioxidant activity by DPPH method with different IC50 values, namely: 130 µg/mL(I), 127 µg/mL(II), 137 µg/mL(III), 129 µg/mL(IV), and 124 µg/ mL(V), respectively. The measurement of total flavonoid content showed 118 mg QE/g (I), 50 mg QE/g (II), 207 mg QE/g (III), 56 mg QE/g (IV), and 55 mg QE/g (V). The IC50 of each sub fractions on HeLa cell were 77 µg/mL, 46 µg/mL, 93 µg/mL, 71 µg/mL and 476 µg/mL; for T47D cell were 1621 µg/mL, 111 µg/mL, 128 µg/mL, 150 µg/mL and 209 µg/mL; and for MCF7 were 259 µg/mL, 343 µg/mL, 575 µg/mL, 408 µg/mL and 250 µg/mL. Based on the results, the fractions derived from ethyl acetate extract of Plectranthus amboinicus (Lour.) Spreng. leaves exhibit antioxidant. The Fraction II from ethyl acetate extract of Plectranthus amboinicus (Lour.) Spreng. was the most cytotoxic on HeLa, T47D and MCF7 cell lines.

Objective/ Background: Cancer is still the most common cause of morbidity in world and new powerful anticancer agents without severe side effects from natural sources is important. Methods: The evaluation of cytotoxicity and apoptosis induction was carried out in MCF-7,HeLa and Saos-2 as cancerous cell lines with different histological origin and human fibroblast served as control normal cell. The cells were treated with different concentrations of chitosan and the cytotoxicity was determined using MTT assay after 24, 48 and 72 h .The mode of death was evaluated by flow cytometry . Results: While both types of chitosan showed significant concentration-dependently cytotoxic effects against the three cancerous cell lines, fibroblast cells showed somehow more compatibility with chitosan. On the other hand, there were no significant differences between LMWC and HMWC cytotoxicity in all cell lines. The flow cytometry results showed the apoptosis pattern of death more in Saos-2 and HeLa while necrosis was more observable with MCF7. Also higher viability with both types of chitosan was seen in fibroblast as normal cells Conclusion: Chitosan shows anticancerous effect against 3 cancerous cell lines, while it is compatible with normal diploid fibroblast cells. Furthermore, it seems that the molecular weight of chitosan does not affect its anticancerous property.

Sarcopoterium spinosum (L.) is a medicinal plant traditionally used for the treatment of various diseases including cancer in the Near- and Middle East. The fractions and constituents of the ethanol extract of S. spinosum were screened for in vitro cytotoxic activities on Jurkat (acute T-lymphoblastic leukemia), HeLa (cervical adenocarcinoma), MCF-7 (mammary gland adenocarcinoma), Caco-2 (human colorectal adenocarcinoma), and MDA-MB-231 (mammary gland adenocarcinoma) cell lines using the MTT (3-(dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The ethanol extract was subsequently re-extracted with ethyl acetate and in its sub-fraction obtained by column chromatography three compounds (stachydrine, benzalkonium chloride and rutine) were the first time identified by nuclear magnetic resonance (NMR) analyses. The most active subfraction showed cytotoxic activity against HeLa, MCF-7, and Caco-2 cell lines. The three compounds mentioned, as standards of high-performance liquid chromatography (HPLC) quality, were studied individually and in combination. Cytotoxic activity observed might be due to the presence of benzalkonium chloride and rutin. Benzalkonium chloride showed the strongest growth suppression effect against HeLa cells (IC50 8.10−7 M) and MCF-7 cells (IC50 5.10−6 M). The mixture of stachydrine and benzalkonium chloride allowed a synergistic cytotoxic effect against all tested cancer and normal cells to be obtained. Anti-cancer activity of the plant extract of S. spinosum remains under-investigated, so this research describes how the three major compounds identified in the ethyl acetate extract can exert a significant dose dependent in vitro cytotoxicity.

Eupatorium odoratum (EO)contains many biologically active compounds, the anticancer effects of which are not well documented. This study evaluates the cytotoxic effects and mechanism of action ofEOextracts on MCF-7 and Vero cell lines. Evaluation of the cytotoxic activity using MTT assay, morphological alterations, and apoptosis were carried out. Autophagy was evaluated by LC3-A protein expression. Cytotoxic activity, membrane blebbing and ballooning at 24 hours, replacement by mass vacuolation, and double membrane vesicles mimicking autophagy and cell death were observed in the cancer cells. No apoptosis was observed by DNA fragmentation assay. Overexpression of LC3-A protein indicated autophagic cell death. Cell cycle analysis showed G0 and G2/M arrest. The Vero cells did not show significant cell death at concentrations <100 μg/mL. These results thus suggest that acetone and ethyl acetate extracts ofEOinduce cell death through induction of autophagy and hold potential for development as potential anticancer drugs.

Abstract Multiple myeloma (MM) is a molecularly heterogeneous hematologic malignancy and remains mostly incurable despite the recent improvement of treatment strategies by several novel agents. Therefore, it is important to develop more efficacious drug against MM. YM155, a novel small molecule suppressant of survivin, shows anti-proliferative activities against various human cancer cells. YM155 was identified in a survivin gene promoter assay by high throughput screening of chemical libraries. In the present study, we investigated the cytotoxic mechanism of YM155 against human myeloma cells including bortezomib (BTZ) resistant cells (U266/BTZ). Three myeloma cell lines, U266, KMS-11 and KMS-12, were employed. YM155 inhibited the cell growth of these cell lines with the IC50 value of below 5 nM. YM155 suppressed the expression of mRNA and protein of survivin. We also found that YM155 inhibited the protein expression of Mcl-1, as an essential anti-apoptotic protein for survival of myeloma cells. In addition, we observed that YM155 markedly suppressed the phosphorylation of STAT3, which is known as transcription factor of Mcl-1. When KMS-12 cells were incubated with IL-6, phosphorylation of STAT3 and upregulation of Mcl-1 protein were observed. Treatment of KMS-12 with YM155 inhibited these events and eventually induced apoptosis in KMS-12 cells. Interestingly, inhibitory effect of YM155 on Mcl-1 protein expression was much stronger than that on survivin. RQ-PCR analysis indicated that the level of Mcl-1 mRNA was not affected after YM155 treatment. Immunoblot analysis showed that proteasome inhibitor MG-132 blocked the inhibition of Mcl-1 expression by YM155, suggesting that proteasome-mediated degradation is involved in YM155-induced Mcl-1 downregulation. MM is a low-growth-fraction disease and low proliferation of MM seems to contribute to resistance to various anticancer drugs. To determine whether YM155 shows cytotoxic effect against quiescent (G0/G1) MM cells, U266 were cultured in low-serum medium to enrich the G0/G1 population. Dual-parametric flow cytometric analysis using Hoechest33342 and the RNA specific dye pyronin Y revealed that YM155 potently induced cell death of quiescent (G0/G1) MM cells. In quiescent MM cells, inhibitory effect of YM155 on Mcl-1 protein expression was much stronger than that on survivin. We also examined whether similar effect of YM155 could be observed in primary MM cells. The majority of primary MM cells from patients was found to be in quiescent phase by cell-cycle analysis. YM155 showed similar cytotoxic activity against primary MM cells. In contrast, Ara-C, the S-phase specific anticancer drug, never killed quiescent primary MM cells. We established BTZ-resistant MM cell line (U266/BTZ). The IC50 value was 45-fold higher than its parental cell line. DNA sequencing data indicated that U266/BTZ cells possess a point mutation, G322A, in the gene encoding the proteasome beta-5 subunit. YM155 almost equally exhibited cytotoxic activity against U266/BTZ compared with parental cells. U266/BTZ displayed significantly lowered amounts of bcl-2, survivin and aurora-B kinase proteins. Interestingly, U266/BTZ overexpressed the Mcl-1 protein. Treatment with YM155 rapidly suppressed Mcl-1 protein expression and induced apoptosis. These data suggest that overexpression of Mcl-1 may contribute to bortezomib resistance and downregulation of Mcl-1 by YM155 could overcome it. In conclusion, our data indicate that YM155 may exert robust cytotoxic activity against quiescent (G0/G1) MM and bortezomib resistant cells via inhibition of Mcl-1 and survivin.
