Isolation and Structure Characterization of Two Novel Bioactive Sulphated Polyhydroxysteroids from the Antarctic OphiuroidOphioderma longicaudum
Two novel sulfated polyhydroxysteroids, I, possessing potent cytotoxic activity, and II, which proved to be cytoprotective against HIV-1, were isolated from the Antarctic ophiuroid Ophiosparte gigas, together with the known compd. III. The structures of I and II were detd. to be cholest-5-ene-2α,3α,...
