Abstract
Three cytotoxic peptides, the known compound Jaspamide and two new peptides, hemiasterlin (Compound 2) and geodiamolide TA (Compound 3), have been isolated from the sponge Hemiasterella minor. The structures of the three were determined by interpreting the NMR and mass spectra. Hemiasterlin (Compound 2) is a novel linear tripeptide embodying two unique, new natural amino acids and geodiamolide TA (Compound 3) is a newly discovered higher homolog of geodiamolides A-F.
