Abstract

Marine environment is known as a source of potential steroids with multiple biological activities, one of which is an anticancer agent. Atactodea striata are one of the seashells distributed in Indonesia located in the Kei Islands, Southeast Maluku. During the course of our continuing search for biologically active substances from Indonesia seashells, seven steroids have been isolated from the n-hexane fraction of A. striata and they were identified as 7β-hydroxy-sitosterol (1), campesterol (2), β-sitosterol (3), cholesterol (4), 5α,8α-epidioxycholest-6-en-3-β-ol (5), 7-keto-cholesterol (6), and 7α-hydroxy-cholesterol (7). The structure was identified by spectroscopic methods including 2D NMR techniques, FTIR, HRTOFMS, and chemical shift comparison with previously reported spectral data. Compounds 1-7 were evaluated for their cytotoxic effects against MCF-7 breast cancer cells and showed weak or no anticancer activity.

Abstract

The Aglaia species, which contains triterpenoids, is the most numerous in the Meliaceae family. The A. cucullata species, of which there are only a few known examples, has received scant research attention. This investigation aims to identify triterpenoids in an n-hexane preparation of A. cucullata stem bark and evaluate their effects against the A549 lung cancer cell line. Five dammarane-type triterpenoids were isolated from the A. cucullata trunk bark, which is (1) (20S)-20-hydroxydammar-24-en-3-one, (2) cabraleone, (3) cabralealactone, (4) eichlerianic acid, and (5) (+)-fouquierol. Their chemical structures were determined using infrared, high-resolution mass spectrometry, and nuclear magnetic resonance, as well as through data comparison of the reported compounds. Compound 1 was priorly separated from the Aglaia genus, compounds 2–4 were first isolated from the A. cucullata species, and compound 5 has been reportedly isolated from the Meliaceae family and the Aglaia genus. All substances were tested for their lethal potential against the A549 lung cancer cell type. A seco structure in the A ring of dammarane-type triterpenoid might play an important part in the lethal activity of component 4, which showed the greatest activity with an IC50 value of 32.17 µM against the A549 lung cancer cell line.
