Abstract

Indonesia is a tropical country with biodiversity and a source of natural compounds such as terpenoids, phenolic, flavonoids, and alkaloid groups. The steroid is one of the large groups of terpenoid compounds with various structures and bioactivities. The steroid was also commonly found in the Meliaceae family. One species of this family is Lansium domesticum Corr. which has been studied to have various activities from isolated compounds (limonoids, sesquiterpenoids, onoceranoids, cycloartanoids, and steroids) as well as from their extracts such as antidiarrheal, antimalarial, antimicrobial, antiinsecticide, antifeedant and were used as traditional medicine such as eye drops and scorpion stings. The n-hexane fraction from the bark of L. domesticum Cor. cv. Kokosan produced steroid compounds whose structure is determined by IR, 1H-NMR, 13C-NMR, and DEPT spectroscopy methods and compared with the literature. It was concluded that the steroid isolated was (22E)-stigmasta-5,22-dien-3ol and was first isolated from this genus. This compound was inactive against MCF-7 breast cancer cells with an IC50 value of 832.14 µM.

Abstract

Chisocheton is a plant of the Meliaceae family which has been known as a source of limonoids, triterpenoids, steroids, alkaloids and phenolics. This plant is the second largest in the Meliaceae, with 53 species widely distributed in tropical and subtropical regions including Indonesia. From this genus, compounds that have interesting activities have been found, including anti-inflammatory, antimalarial, cytotoxic, antitumor and anticancer. One of the species that has the potential to find new compounds is Chisocheton lasiocarpus because there are still few phytochemical studies. This study aims to inform the structural elucidation of one of the compounds from the stem bark of C. lasiocarpus, namely morelloflavone and its cytotoxic potential against breast cancer cells using the in silico method against ER-α receptors (PDB code: 3ERD), ER-β (PDB code: 1QKM). ) and HER-2 (GDP code: 3PP0).

Abstract

ABSTRACT. Sesquiterpenoids are a class of terpenoid compounds with a remarkable diversity of structures and biological activities. Sesquiterpenoids are primarily found in higher plants, such as the Meliaceae family's Aglaia genus. Aglaia cucullata is a species of Aglaia that is still rarely explored and can potentially contain sesquiterpenoid compounds with cytotoxic activity. Hence, the research intended to isolate sesquiterpenoids from the n-hexane extract of A. cucullata stem bark and evaluate their cytotoxic effect against A549 lung cancer cells. Compounds 1 and 2 were isolated and purified from n-hexane extracts utilizing various chromatographic techniques. The structure of compounds 1 and 2 was determined by analyzing various spectroscopic methods (IR, MS, and NMR) and comparing them to previously reported spectral data. Compound 1 was identified as an isodaucane-type sesquiterpenoid, 10-hydroxy-6,10-epoxy-7(14)-isodaucane, and was first reported in Meliaceae family. Compound 2 was confirmed as an eudesmane-type sesquiterpenoid, eudesm-4(15)-ene-1β,6α-dihydroxy, and was first reported in Aglaia cucullata. Cytotoxic activity of 1 and 2 were investigated in vitro against A549 lung cancer cells using the PrestoBlue assay and resulted in inactive and low cytotoxicity with IC50 values of 292.77 and 90.55 μM, respectively. Key words: Aglaia cucullata, , A549 cell lines, cytotoxic activity, Meliaceae, sesquiterpenoids.

Abstract

ABSTRACT. Limonoid group belongs to triterpenoid that has undergone further oxidation accompanied by the loss of four carbon atoms to form a furan ring in the chain. This limonoid compound is often found in the Chisocheton genus. Limonoid compounds have been known as compounds with high structural variations and this makes limonoids have diverse and interesting activities, including cytotoxic and anticancer. In the course of our continuing study for limonoid constituents that have cytotoxic activity against cancer cell lines, methanol extract of stem bark from the Chisocheton pentandrus plant provides significant activity. The methanol extract was separated using various chromatographic techniques in the normal and reverse stationary phase to produce four azadirone-type limonoid compounds (1-4). The elucidation structure of 1-4 was determined using spectroscopic methods including, UV-Visible, IR, and 1D-NMR as well as optical rotation. All four known compounds were established as trichilenone acetate (1), toonaciliaton C (2), 11α-acetoxiazadiron (3), and 16β-hydroxydisobinine (4). The cytotoxicity of compounds 1-4 was assessed by examination using the resazurin method, which showed that compound 4 was the promising constituent against the MCF-7 cells with an IC50 value of 43.1 µM and was stronger than its positive control. Keywords: Azadirone-type limonoid, Chisocheton pentandrus, cytotoxic activity, Meliaceae.
