Aeruginazole A, a novel thiazole-containing cyclopeptide from the cyanobacterium Microcystis sp

Org Lett. 2010 Aug 6;12(15):3536-9. doi: 10.1021/ol1014015.

Abstract

A novel thiazole-containing cyclic peptide, aeruginazole A (1), was isolated from the cyanobacterium Microcystis sp. strain (IL-323), which was collected from a water reservoir near Kfar-Yehoshua, Valley of Armageddon, Israel. The planar structure of aeruginazole A was established using homonuclear and inverse-heteronuclear 2D NMR techniques, as well as high-resolution mass spectrometry. The absolute configuration of the asymmetric centers was determined using Marfey's method. Aeruginazole A potently inhibited Bacillus subtilis.
