Abstract | Fractions of trisulfated trihydroxysteroids from the sponges Trachyopsis halichondroides (two different collections) and Cymbastela coralliophila have been isolated and investigated. Ten triacetates were obtained from these fractions by desulfatation/acetylation followed by chromatographic separation, and their structures have been established. Four of these derivatives-namely, triacetates of 5α-pregnance-2β,3α,6α-triol (3c), 23,24-dinor-5α-cholane-2β,3α,6α-triol (4c), 5α-cholest-22-ene-2β,3α,6α-triol (7c), and 24-isopropyl-5α-cholestane-2β,3α,6α-triol (11c)-are described as new derivatives of natural steroids. © 1995. |
