Abstract
Desmosterol (1), 24,25-epoxycholesterol (2), 24-hydroperoxycholesta-5, 25-dien-3 beta-ol (3), 25-hydroperoxycholesta-5,23(E)-dien-3 beta-ol ( 4), cholesta-5,25-diene-3 beta,24-diol (5), and 24,25-epoxy-6 beta-hyd roxycholest-4-en-3-one (7) were isolated from the marine red alga Gala xaura marginata; sterols 3, 4, and 7 were isolated for the first time from a natural source. Sterols 3-7 exhibited significant cytotoxicity toward serveral cancer cell lines.
