A novel group of polyhydroxycholanic acid derivatives from the deep water starfish Styracaster caroli De Riccardis, F. Minale, L. Riccio, R. Iorizzi, M. /Debitus, Cécile /Duhet, Daniel Monniot, C. SUBSTANCE NATURELLE INVERTEBRE AQUATIQUE ETOILE DE MER STRUCTURE CHIMIQUE POLYHYDROXYSTEROIDE ACIDE POLYHYDROXYLCHOLANIQUE ACIDE CYSTEINOLIQUE Three novel polyhydroxysteroid constituents have been isolated from the starfish Stracaster caroli collected at a depht of 2000 m off New Caledonia. These, designated carolisterols A - C (1 - 3), are characterized by a polyhydroxycholanic acid moiety, in which the 24-carboxylic acid function is found as an amide derivative ofD-cysteinolic acid.
