Abstract:
Three new and two known sulfated steroidal polyols have been isolated from the Antarctic ophiuroid Astrotoma agassizii. All of the new steroids possess a terminal isopropenyl group and a C-21 sulfoxy moiety in the side chain but differ in the steroidal nuclei. The structures of these new steroids were established from spectral and chemical correlations with related steroids as (20R)-cholesta-5,24-diene-2β,3α,21-triol 2,21-disulfate (1), (20R)-5α-cholest-24-ene-2β,3α,21-triol 3,21-disulfate (3), and (20R)- cholesta-5,24-diene-2α,3α,4β,21-tetrol 3,21-disulfate (5). Analysis of the nonsulfated sterol fraction has shown the presence of cholest-5-en-3β-ol, cholesta-5,24-dien-3β-ol and (22E) cholesta-5,22-dien-3β-ol as the major sterols.
