Abstract
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,4β, 21-tetraol 3,21-disulfate and cholest-5-ene-2β,3α, 21-triol 2,21-disulfate, resp.File in questo prodotto:
