A novel cyclopeptide from a bacterium associated with the marine sponge Ircinia muscarum

Z Naturforsch C J Biosci. 2003 Sep-Oct;58(9-10):740-5. doi: 10.1515/znc-2003-9-1026.

Abstract

A new cyclotetrapeptide 1, together with three known cyclopeptides were isolated from the exo-cellular extract of Pseudomonas sp. a bacterium associated with the sponge Ircinia muscarum. The structure of 1 was suggested on the basis of spectroscopic analytical data and chemical degradation.
