Cyanopeptolin S, a sulfate-containing depsipeptide from a water bloom of Microcystis sp.


A new sulfated, cyclic depsipeptide, called cyanopeptolin S, from Microcystis sp. was isolated from a water bloom in the Auensee/Leipzig (Germany). The depsipeptide had a relative molecular mass of 925 and contained L-arginine, L-threonine, L-isoleucine, N-methyl-L-phenylalanine, a L-glutamic acid-delta-aldehyde ring system and a sulfated D-configurated… (More)
