<p>Indonesia merupakan negara yang kaya akan keanekaragaman hayati. Terdapat banyak tanaman yang mengandung senyawa metabolit sekunder yang memiliki aktivitas biologi sehingga berpotensi untuk digunakan sebagai obat, salah satunya adalah genus <em>Chisocheton</em>. Tanaman genus <em>Chisocheton </em>sudah banyak dilaporkan mengandung senyawa triterpenoid, seskuiterpenoid, limonoid, steroid, dan fenol. Limonoid merupakan turunan triterpenoid yang paling banyak ditemukan pada tanaman genus <em>Chisocheton</em>. Lebih dari tiga puluh senyawa golongan limonoid telah diuji aktivitas antikankernya terhadap beberapa jenis sel kanker manusia, seperti sel kanker payudara, mulut, paru-paru, leukimia, serviks, dan hati. Beberapa senyawa limonid tersebut diketahui memiliki aktivitas sitotoksik yang tinggi dengan kisaran nilai IC<sub>50</sub> 1,67 − 50,27 µg/mL. Review ini memaparkan beberapa senyawa limonoid yang diisolasi dari genus <em>Chisocheton</em>, aktivitas sitotoksiknya terhadap sel-sel kanker manusia, serta hubungan struktur dan aktifitas biologisnya (SAR = <em>Structure Activity Relationship</em>). Selain itu beberapa penelitian juga sudah melakukan penelitian lebih lanjut seperti pengujian induksi apoptosis dan penentuan tingkat ekspresi gen-gen yang berhubungan dengan apoptosis. Penelitian-penelitian yang dilakukan ini mengarah pada pencarian senyawa baru yang dapat digunakan sebagai <em>lead compound</em> untuk mendapatkan obat antikanker yang efektif.</p><p><strong></strong><strong>Limonoid Compounds from Genus <em>Chisocheton </em>Plant and Its Anticancer Activity. </strong>Indonesia is a country with a large biodiversity. There are many plants contain secondary metabolite compounds with biological activity, such as <em>Chisocheton</em> genus. The <em>Chisocheton</em> is reported as plant with triterpenoids, sesquiterpenoids, limonoids, steroids and phenols content. Limonoids arethe derivative of triterpenoid which mostly found in <em>Chisocheton</em> genus. More than thirty limonoids have been studied for their anticancer activity against several types of human cancer cells, such as breast, mouth, lung, leukemia, cervical, and liver cancer cells. Some of these limonoids are known to have high cytotoxic activity with the IC<sub>50</sub> values of 1.67 − 50.27 µg/mL. This review discuss many kind of limonoid compounds isolated from <em>Chisocheton</em>, their cytotoxic activity against human cancer cells, and their structural activity relationship (SAR) study. This review also discusses some research result for further studies of <em>Chisocheton</em> wether in the mechanism of apoptosis induction and also the determination genes level expression or proteins associated with the apoptosis. This review reveals the important of the study to find a new compounds for an effective anticancer drug.</p>

Five conjugated polyene ketones (1-5) were isolated from the methanol extract of the marine sponge Clathria ( Thalysias) reinwardti (Vosmaer, 1880) living in the coastal waters of Vietnam. Their structures were determined to be 8-(2′,3′,4′-trimethylphenyl)-6-methyl-oct-3( E),5( E),7( E)-trien-2-one (1), 13-apoastaxanthinone (2), 9-apoastaxanthinone (3), 2,3-dehydro-4-oxo- β-ionone (4), and 4-(2′,3′,4′-trimethylphenyl)-but-3( E)-en-2-one (5), by extensive analysis of high-resolution electron spray ionization mass spectrum (HR-ESI-MS), one-dimensional, and two-dimensional (2D) nuclear magnetic resonance (NMR) spectra, as well as by comparison of the spectral data with those reported in the literature. Compound 1 was new, compounds 2 to 4 were isolated from nature for the first time, and the chemical structure as well as the NMR assignments, of 5 were indicated by 2D NMR for the first time. Additionally, compound 5 exhibited cytotoxic activity against the human cancer cells SK-LU-1, SK-Mel-2, MCF-7, and Hep-G2 with half-minimal inhibitory concentration (IC50) values of 15.12 ± 3.43, 17.41 ± 2.83, 33.12 ± 3.39, and 34.38 ± 3.52 µM, respectively, but displayed only a weak cytotoxic effect on the normal HEK-239A cells (IC50 64.67 ± 3.67 µM). Compound 5 also significantly increased Caspase-3 activity in SK-LU-1 cells at concentrations of 10, 15, and 20 µM.

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.

Plants are an invaluable source of potential new anti-cancer drugs.Momordica charantiais one of these plants with both edible and medical value and reported to exhibit anticancer activity. To explore the potential effectiveness ofMomordica charantia, methanol extract ofMomordica charantia(MCME) was used to evaluate the cytotoxic activity on four human cancer cell lines, Hone-1 nasopharyngeal carcinoma cells, AGS gastric adenocarcinoma cells, HCT-116 colorectal carcinoma cells, and CL1-0 lung adenocarcinoma cells, in this study. MCME showed cytotoxic activity towards all cancer cells tested, with the approximate IC50ranging from 0.25 to 0.35 mg/mL at 24 h. MCME induced cell death was found to be time-dependent in these cells. Apoptosis was demonstrated by DAPI staining and DNA fragmentation analysis using agarose gel electrophoresis. MCME activated caspase-3 and enhanced the cleavage of downstream DFF45 and PARP, subsequently leading to DNA fragmentation and nuclear condensation. The apoptogenic protein, Bax, was increased, whereas Bcl-2 was decreased after treating for 24 h in all cancer cells, indicating the involvement of mitochondrial pathway in MCME-induced cell death. These findings indicate that MCME has cytotoxic effects on human cancer cells and exhibits promising anti-cancer activity by triggering apoptosis through the regulation of caspases and mitochondria.
