Bioactivity-guided fractionation of MeOH extract of an association of two sponges, Jaspis sp. and Poecillastra sp. resulted in isolation of four apocarotenoids (1 - 4). Their structures were determined on the basis of MS and NMR spectroscopic analyses and by direct comparison with those of reported. This is the first report on isolation of these compounds from any sponge. Isolated metabolites were evaluated for cytotoxicity against a small panel of solid human tumor cell lines.
