Abstract
Four novel oxygenated desmosterols, 24 xi-hydroperoxy-6 beta-hydroxych olesta-4,25-dien-3-one (1), 25-hydroperoxy-6 beta-hydroxycholesta-4,23 (E)-dien-3-one (2), 24 xi-hydroperoxycholesta-4,25-diene-3,6-dione (3) , and 25-hydroperoxycholesta-4,23(E)-diene-3,6-dione (4) were isolated from the marine red alga Galaxaura marginata. Steroids 1-4 and three synthetic oxygenated desmosterols 5-7 were shown to exhibit significan t cytotoxicity against several cancer cell lines.
