title: Metabolites of Microcystis aeruginosa bloom material from Lake Kinneret, Israel.
abstract: Six new metabolites, micropeptin KT1042, microguanidine KT636, aeruginosins KT608A, KT608B, and KT650, and pseudoaeruginosin KT554, were isolated along with the known micropeptins SF909 and HM978, cyanopeptolin S, anabaenopeptin F, and the two isomers of planktocyclin-S-oxide from a bloom material collected from Lake Kinneret, Israel, in March 2005. The structure elucidation and biological activity of the six new natural products isolated from this bloom material and the related aeruginosin GH553 are described.
