Chemistry of natural compounds and bioorganic chemistry: Steroid compounds from the Pacific starfishes Luidia quinaria and Distolasterias elegans

Article abstract of DOI:10.1007/bf01433994

One new and four previously known steroid compounds were identified from the Pacific starfishes Luidia quinaria and Distolasterias elegans. The structure of the new steroid was established from spectral data and chemical correlations with other steroids such as 5α-cholestane-3β,5,6β,15α,16β,26-hexaol 3-sulfate (1). The previously known compounds were identified as 5α-cholestane-3β,5,6β,15α,26-pentaol 15-sulfate (2) from Luidia quinaria and sodium (24S)-O-[β-D-glucopyranosyl]-5α-cholestane-3β,6α,8, 15β,24-pentaol 6′-sulfate (3), sodium (24S)-5α-cholestane-3β,6α,8,15β,24-pentaol 24-sulfate (4), and sodium tornasterol A sulfate (5).
