Abstract
A new purine derivative, 6-methoxy-7-methyl-8-oxoguanine (1), along with 8- oxoadenine (2) and the human metabolite S-methylxanthine (3), has been isol ated from the ascidian Symplegma rubra collected on the southeastern coastl ine of Brazil. The structures of the three purines were established by anal ysis of spectroscopic data.
