Abstract

Three cytotoxic peptides, Jaspamide (1) and the two new peptides hemiasterlin (2) and geodiamolide TA (3), have been isolated from the sponge Hemiasterella minor. The Extractures of the three were determined by interpretating the NMR and mass spectra.Hemiasterlin (2) is a novel linear tripeptide embodying two unique, new natural aminoacids and geodiamolide TA (3) is a higher homologe o
