摘要: The present invention is directed to two novel compounds isolated from a Pacific sponge, Plakortis (Homosclerophorida, Plakinidae) which are designated herein as epidioxymanadic acids A and B. These two compounds have been obtained by a bioassay-guided (i.e., antibiotic activity) isolation procedure, involving solvent partition and chromatography on Sephadex LH-20, cyano, and C-18 columns, from extracts of sponge. ##STR1##
