Abstract

In the course of our screening program for inhibitors of lipopolysaccharide binding to cellular receptor CD14, a potent inhibitory activity was detected in the cultured broth of Pseudoalteromonas sp. SANK 71903. Four active compounds, ogipeptins A, B, C and D, were isolated from the cultured broth. The structures of these compounds were elucidated by physicochemical data and spectral analyses, and they were determined to be new cyclic lipopeptides.
