The blue marine sponge Cribrochalina sp., collected in the Republic of Maldives was found to contain new cell growth inhibitors denominated cribrostatin 3, cribrostatin 4 and cribrostatin 5 which were found to be active against the NCI human melanoma panel and the P388 marine lymphocytic cell lines employed by the U.S. National Cancer Institute. Structural determination of all three substances were accomplished utilizing high yield NMR (400 MHz) and mass spectral studies. Cribrostatins 3-5 were also found to possess significant antibacterial and antifungal activity.
