Three new cytotoxic sesterterpenes from a marine sponge Spongia sp.
Three new sesterterpenes (1-3) were isolated from a marine sponge of the genus Spongia, and their structures were determined on the basis of spectroscopic analysis. The compounds 1-3 exhibited cytotoxicity against HeLa cells with IC(50) values of 19.5, 15.0, and 5.3 microg/mL, respectively.
