Westiellamide, a Bistratamide-Related Cyclic Peptide from the Blue-Green Alga Westiellopsis prolifica

Abstract

The isolation and structural elucidation of westiellamide [1] from the terrestrial blue-green alga Westiellopsis prolifica is described. This moderately cytotoxic cyclic peptide appears to be identical with a bistratamide-type marine natural product from the aplouso-branch ascidian Lissoclinum bistratum.
