A novel sulphated steroid with a 7-membered 5-oxalactone B-ring from an antarctic starfish of the family Asteriidae
Three novel sulphated polyhydroxylated steroids, named asterasterols A-C (1-3), have been isolated from an Antarctic starfish of the family Asteriidae and their structures elucidated by spectroscopic studies. Steroid 1 has the seven-membered 5-oxalactone B-ring; 2 and 3 are the corresponding 6-oxo s...
