Cancer is one of the leading cause of death in the world. Complicated and high cost treatments of cancer encourages people to look for alternative treatments among others using medicinal plants. Some medicinal plants that are empirically claimed to have anticancer effect are soursop (Annona muricata), takokak (Solanum torvum), and bidara upas (Merremia mammosa). However, these medicinal herbs have not been tested for cytotoxic activity against MCF-7 cancer cells. The purpose of this study was to determine the cytotoxic activity of the anticancer herbal formula consisting those three plants. The effect of each single extract and the combination formula were tested for their activity on cell viability of MCF-7 with MTT assay method. The herbal formula with the most active combination of medicinal plant extracts was further tested for its activity on the expression of Bcl-2 protein by immunocytochemistry methods. The results showed that each single extract and the combination formula gave cytotoxic effect on MCF-7 breast cancer cells. Formula A, consisted of a mixture of soursop leaves, takokak fruit, and bidas upas bulb with a ratio of 1:1:1, results in highest inhibition of the viability of MCF-7 cells with IC50 values of 48 µg/ml. The formula also enhances the apoptosis process in MCF-7 cells which is shown by decreasing the expression of antiapoptotic Bcl-2 proteins.

Background: For further exploration of the promising pyrrolizine scaffold and in continuation of our previous work, that proved the potential anticancer activity of the hit compound I, a new series of pyrrolizines 2-5 and 7-9 were designed and synthesized. Methods: Structures of the new compounds were confirmed by IR, 1H-NMR, 13C-NMR and elemental analysis. Antitumor activity for the prepared compounds against human breast adenocarcinoma (MCF-7), liver (HEPG2) and colon (HCT116) cancer cell lines was evaluated using SRB assay method. Result: Compounds 2, 3 and 5 were the most potent on colon cancer cells, their IC50 values were less than 5 µM. Compounds 2, 3 and 8 were the most potent on liver cancer cells, their IC50 values were less than 10 µM. As for MCF7, compounds 2, 7, 8 and 9 were the most active with IC50 values less than 10 µM. We can conclude that combining pyrrolizine scaffold with urea gave abroad spectrum anticancer agent 2 against the three tested cell lines. Micronucleus assays showed that compounds 2, 3, 8 are mutagenic and can induce apoptosis. In addition, caspase-3 activation was evaluated and compound 2 showed increase in the level of caspase-3 (9 folds) followed by 3 (8.28 folds) then 8 (7.89 folds). Conclusion: The obtained results encourage considering these three compounds as novel anticancer prototypes.

Background: Erythrina poeppigiana (Leguminosae) is a high-growing plant with an orange flower that is widely distributed in tropical and subtropical countries. This particular plant is widely used in traditional medicine for gynecological complications and the treatment of various diseases. There exists no previous information regarding cytotoxic compounds from this plant. Objective: This research is to isolate cytotoxic compounds from E. poeppigiana. Methods: The isolation step was carried out using a combination of chromatographic techniques to obtain isolated three compounds (1, 2, and 3). Results: The chemical structure of isolated compounds was elucidated by spectroscopic methods and identified as β-erythroidine (1), 8-oxo-β-erythroidine (2), and 8-oxo-α-erythroidine (3). Compounds (1-3) showed cytotoxic activity against MCF-7 breast cancer line with IC50 values of 36.8, 60.8 and 875.4 μM, respectively. Conclusion: Three compounds have been successfully isolated from Erythrina poeppigiana (Leguminosae), showing cytotoxic properties against MCF-7 breast cancer line. Structure-activity relationship studies showed that the presence of enone moiety on compound 1 can reduce its cytotoxic activity towards MCF-7 breast cancer line.

Objective: Alysicarpus monilifer (Family Papilionaceae) has been used in the Indigenous system of medicine in tumor removal. The present study was designed to isolate and identify the constituent responsible for cytotoxic (anti-tumor) effects of the plant Alysicarpus monilifer. Methods: The plant was powdered and extracted to give a methanolic extract. Initially, Hexane, chloroform, ethyl acetate and methanolic fractions of the methanolic extract of the plant were subjected to cytotoxic screening using cell line based assay (MTT assay and NRU assay). The chloroform fraction showed significant cytotoxicity, so it was further subjected to column chromatography, to separate the cytotoxic phytoconstituent. The cell lines selected were breast cancer cells (MCF-7 and MDA-MB-468) and Liver cancer cells (HepG2 and HLE cell). Results were calculated as percentage growth inhibition with respect to untreated (control) cells versus treated cells. Result: A triterpene, Betulinic acid, was isolated from the aerial parts of Alysicarpus monilifer. The cytotoxic activity of the identified compound against MCF-7, MDA-MB-231, HLE and HepG2 cells was also found to be highly significant with 90% growth inhibition. Conclusion: The triterpene was identified to be betulinic acid, to which the cytotoxic activity can be attributed. It is a first report of isolation of betulinic acid from the Alysicarpus species.

Maytenus disticha (Hook F.), belonging to the Celastraceae family, is an evergreen shrub, native of the central southern mountains of Chile. Previous studies demonstrated that the total extract of M. disticha (MD) has an acetylcholinesterase inhibitory activity along with growth regulatory and insecticidal activities. β-Dihydroagarofurans sesquiterpenes are the most active components in the plant. However, its activity in cancer has not been analyzed yet. Here, we demonstrate that MD has a cytotoxic activity on breast (MCF-7), lung (PC9), and prostate (C4-2B) human cancer cells with an IC50 (µg/mL) of 40, 4.7, and 5 µg/mL, respectively, an increasing Bax/Bcl2 ratio, and inducing a mitochondrial membrane depolarization. The β-dihydroagarofuran-type sesquiterpene (MD-6), dihydromyricetin (MD-9), and dihydromyricetin-3-O-β-glucoside (MD-10) were isolated as the major compounds from MD extracts. From these compounds, only MD-6 showed cytotoxic activity on MCF-7, PC9, and C4-2B with an IC50 of 31.02, 17.58, and 42.19 µM, respectively. Furthermore, the MD-6 increases cell ROS generation, and MD and MD-6 induce a mitochondrial superoxide generation and apoptosis on MCF-7, PC9, and C4-2B, which suggests that the cytotoxic effect of MD is mediated in part by the β-dihydroagarofuran-type that induces apoptosis by a mitochondrial dysfunction.

Crystals of Ph3SnCl (1) were grown from a methanol/acetonitrile solution. Compounds [Ph3SnOH]n (2) and [(Ph2Sn)4Cl2O2(OH)2] (3) were crystallized from diethyl ether/methanol/acetonitrile and hot acetone/water solutions respectively, of the white precipitation, formed by adding KOH to solutions of 1 and [Ph2SnCl2] in 1 : 1 and 1 : 2 molar ratios respectively. Complex 1 was characterized by X-ray crystallography. X-ray structure determination of compounds 2 and 3 confirmed the previously reported identities. The molecular structure of 1, reported here, is a new polymorphic form of the known one for Ph3SnCl. Four independent [Ph3SnCl] molecules constitute the crystal structure of 1. The moieties are packed in two pairs in a tail-to-tail arrangement. Complexes 1–3 were evaluated for their in vitro cytotoxic activity (cell viability) against human cancer cell lines: HeLa (human cervical), MCF-7 (breast, estrogen receptor (ER) positive), MDA-MB-231 (breast, ER negative), A549 (lung), Caki-1 (kidney carcinoma), 786-O (renal adenocarcinoma), K1 (thyroid carcinoma), and the normal human lung cell line MRC-5 (normal human fetal lung fibroblast cells) versus, the normal immortalized human mammary gland epithelial cell line MTSV17 with a sulforhodamine B (SRB) assay. The results show potent cytotoxic activity of the complexes against all cell lines used, which was superior to that of cisplatin (CDDP). Compounds 1–3 showed higher activity against breast cancer cells MCF-7 (ER positive) than against of MDA-MB-231 (ER negative). These findings prompted us to search for possible interaction of these complexes with other cellular elements of fundamental importance in cell proliferation. The influence of these complexes 1–3 upon the catalytic peroxidation of linoleic acid to hydroperoxylinoleic acid by the enzyme lipoxygenase (LOX), as well as their binding affinity towards calf thymus-DNA, were kinetically and theoretically studied.

Cancer remains one of the diseases with increasing number of sufferers, but research on compounds that act as anti-cancer is also ongoing. Terpenoids have been known as a compound that can inhibit the proliferation of cancer cells. One of the medical plants that produce terpenoids is Jarak cina (Jatropha multifida Linn.). Therefore, the possibility of Jarak cina (Jatropha multifida Linn.) to have an cytotoxic activity on cancer cell proliferation is reasonably high. This study was conducted to determine the cytotoxic activity of Jarak cina (Jatropha multifida Linn.) bark extracts against cancer cell MCF-7. Jarak cina bark was extracted using the multilevel soxhlet extraction method with n-hexane, ethyl acetate, and ethanol as the solvents. All the three extracts were then tested against MCF-7 cancer cells using MTT (3-(4,5-dimethylthiazol-2-yl) - 2,5-diphenyltetrazolium bromide) method. Data analysis was performed for IC50 (ppm) parameter. The results showed that the IC50 of n-hexane extract was 313.21 ppm, while the ethyl acetate extract reached 258.38 ppm of IC50, and the IC50 of ethanol extract was 418.51 ppm. The highest potential of cytotoxicity was found in the ethyl acetate extract, so further testing would be required to optimize the proliferation inhibitory activity.

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.
