  • 4 Downloads

Further chemical investigation of the marine sponge Topsentio sp. collected from the South China Sea led to the isolation of two new polyhydroxylated sterol derivatives, topsensterol D (1) and 4β-hydroxyhalistanol (2). Their structures were elucidated by detailed analysis of the spectroscopic data including 1D and 2D NMR spectral data. Their cytotoxic activities were evaluated.
