Abstract

Three new depsipeptides, malevamides A-C (1-3), were isolated from the cyanobacterium Symploca laete-viridis collected off the south shore of Oahu, Hawaii. Compounds 1-3 were identified by spectral methods, and partial stereochemical assignments were made by chiral HPLC of the hydrolyzed compounds. At a concentration of 2 microg/mL, compounds 1-3 were inactive against P-388, A-549, and HT-29 cancer cells.
