Abstract

Marine sponges have been recognized as potentially rich sources of various bioactive molecules. In our continuing search for new secondary metabolites from Indonesian marine invertebrates, we collected a sponge, whose extract showed cytotoxicity against cultured cells at 0.1 μg/mL. Purification of the extract yielded two new macrolides 2 and 3 along with known candida spongiolide (1). The structures for compounds 2 and 3 were elucidated by spectral analysis (1H,13C,COSY,HMQC, HMBC) and by comparison of their NMR data with those of 1. Compounds 2 and 3 exhibited a little more potent cytotoxicity (IC 4.7 and 19 ng/mL) than that (IC5037 ng/mL) of candida spongiolide (1) against NBT-T2 cells
