Abstract

Chemical investigation of methanolic extracts of the two Indonesian marine sponges Stylissa massa and Stylissa flabelliformis yielded 25 bromopyrrole alkaloids including 2 new metabolites. The structures of all isolated compounds were unambiguously elucidated based on extensive 1D and 2D NMR, LR-MS and HR-MS analyses. All isolated compounds were assayed for their antiproliferative and protein kinase inhibitory activities. Several of the tested compounds revealed selective activity(ies) which suggested preliminary SARs of the isolated bromopyrrole alkaloids.
