Abstract

The acyclic peptide tasiamide (1) has been isolated from the marine cyanobacterium Symploca sp. The planar structure and absolute stereochemistry of the peptide were deduced by 2D NMR techniques and chiral HPLC. Tasiamide (1) was cytotoxic against KB and LoVo cells with IC(50) values of 0.48 and 3.47 microg/mL, respectively.
