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