Cytotoxic activity of Bufotalin was determined by MTT assay at various concentrations ranging from 0.002 to 0.008 μmol/ml on Hela cells. The Apoptosis and its mechanism induced by Bufotalin was also studied. The results showed Bufotalin displayed the marked inhibition effect to Hela cells and the IC50 value is 0.0045 μmol/ml for 24 hour. The procaspase-3,-8 and-9 decreased and their active cleaved forms increased treated with Bufotalin at concentrations from 0.002 to 0.006 μmol/ml. These data suggest that the pro-apoptotic effect of Bufotalin is mediated through activation of caspases and mitochondria in Hela cells.

Cervical cancer is one type of cancer that attacks women in both developed and developing countries. Cancer can arise from cell division errors or DNA damage from certain environmental exposures that cause free radicals as a factor of cancer cells. The agarwood plant (Aquilaria malaccensis  Lam) has been known by society as a health tea ingredient. The content of compounds contained in tea is believed to have anti-cancer and antioxidant activity. In previous studies found some of the active compound ingredients contained in the leaves of agarwood, such as alkaloids, flavonoids, triterpenoid, saponins and tannins. Tests that have been done previously that agarwood plants have good cytotoxic activity against cancer cells MCF-7 from one of the fractions, the n-hexane fraction. In this study, another cytotoxic potential test was carried out from aloe plants on other cancer cells, namely HeLa cells. Extraction was carried out by the Soxhletation method using 96% ethanol solvent, then fractionated with n-hexane solvent, ethyl asetate, and methanol: water. The MTT assay method is used to test the cytotoxic activity of sample research on cell cultures used. Measurements were performed using an ELISA reader at 550 nm wavelength. The results showed that the IC50 values of the four samples tested were ethanol extract (299,506 µg / ml), n-hexane fraction (120,913 µg / ml), ethyl acetate fraction (3490,476 µg / ml) and methanol fraction: water (294,060 µg) / ml). from extracts and fractions it is known that the highest value is shown by the n-hexane fraction in the moderately active/moderate category.

The cytotoxicity of Desacetylcinobufotalin (DEBF) and apoptosis induced by DEBF was measured. Additionally the mechanism of Apoptosis induced by DEBF was studied through Western blot. The results show DEBF displayed the marked inhibition effect to HepG2 cells and the IC50value is 0.0279μmol/ml. The expression of Bax was significantly increased and the expression of Bcl-2 was markedly decreased, compared to the control. The data suggest DEBF had significant antitumor activity through induction apoptosis via mitochondria pathway.

Promising Therapeutic Approach

: Cervical cancer is one of the frequent types of cancer seen in females. It has been suggested that natural compounds can be used effectively for cancer treatment. Apoptosis and autophagy related cell death play important roles in suppression of tumorigenesis. Apigenin and curcumin are natural products isolated from plant extracts known to have antitumoral, antibacterial and antiviral effects. Varying doses of curcumin and apigenin were applied to HeLa cancer cell lines. The expression of the genes related to apoptosis and/or autophagy related cell death were measured using qRT-PCR and cell viability was measured using MTT assay. Our results showed that curcumin and apigenin are effective on apoptosis and autophagy related cell death in HeLa cells. We suggested that these natural products seem to be a new promising therapeutic approach in cancer.

Induction Of Apoptosis

Breast cancer is the most dominant type of cancer in Indonesia. Traditional medicine using tapak liman (Elephantopus scaber L.) as an anticancer becomes an option because it contains compounds such as sesquiterpenes. The purpose of this study was to know the cytotoxic activity of ethanolic extract of tapak liman on T47D cells through induction of apoptosis. The extraction method uses maceration with 96%. Total flavonoids were tested using quercetin as a spectrophotometric standard. ethanol solvent, cytotoxic test using microtetrazoliom (MTT assay), and apoptosis test using double staining test (ethidium bromide-acrydine orange) under a fluorescence microscope. The results showed the linear regression equation y = 0.0934x-0.0292 with the resulting flavonoid levels of 0.979% w / w calculated against quercetin (QE) The concentration of the compound used was 1000 µg/ml; 500 µg/ml; 250µg/ml; 125 ?g/ml, 62.5 ?g/ml; 31.25 µg/ml. The MTT assay results are the values of IC50 which are analyzed using probit analysis and apoptosis tests which are analyzed descriptively. The results of the research show that the ethanol extract of tapak liman using MTT method has IC50 value of 59 µg/ml, while the testing of double staining method shows the color of bright green which indicates early apoptosis and the color orange in the cells which undergoing final apoptosis. DNA fragmentation results shows that Tapak Liman extract induces DNA fragments. The conclusion of this study is that tapak liman textract has the potential for cytotoxic activity against T47D breast cancer cells through the induction of apoptosis

Cancer chemotherapies may result in resistance, and therefore, contemporary treatments including natural products may find an increasing consideration. As per Persian medicine (PM), many natural products have been used for malignant and chronic diseases. Triphala, with a combination of Terminalia chebula Retz., Terminalia bellirica Retz., Phyllanthus emblica L., and honey, is a multi-ingredient traditional formulation attributed to anticancer activities in PM. This study is aimed at evaluating the cytotoxic activity of this preparation on HepG2, the human liver cancer cell line. Hydroalcoholic extracts were prepared from the formulation and its components. Compared with the control and Cisplatin, the extracts were tested using MTT assay at different concentrations. All concentrations of the preparation, as well as Cisplatin, were effective significantly against HepG2 cells. All extract preparations at multiple concentrations were significantly effective as evidenced by MTT assay when compared to the control group. The IC50 level for Triphala extract was 77.63 ± 4.3   μ g / ml . Based on the results, Triphala and its components have cytotoxic activity on the HepG2 cancer cell line and they can reduce the survival rate significantly.
