Definition:A member of the class xanthones which consists of a dihydroxanthone skeleton substituted by a acetyloxy group at position 4, a hydroxy group at position 8, a methyl group at position 6 and a methoxycarbonyl group at position 4a (the 4R,4aS stereoisomer). It is isolated from Penicillium and exhibits potent antitumour activity against both human and murine tumour cell lines.
Synonyms:exact_synonym: methyl (4R,4aS)-4-(acetyloxy)-8-hydroxy-6-methyl-9-oxo-4,9-dihydro-4aH-xanthene-4a-carboxylate
