Three novel polyhydroxysteroid constituents have been isolated from the starfish Styracaster caroli collected at a depth of 2000 m off New Caledonia. These, designated carolisterols A-C (I, R = OH, R' = OH; II, R = OH, R' = O; III, R = H, R' = OH), are characterized by a polyhydroxycholanic acid moiety, in which the 24-carboxylic acid function is found as an amide deriv. of D-cysteinolic acid.

Abstract
Three novel polyhydroxysteroid constituents have been isolated from the starfish Styracaster caroli collected at a depth of 2000 m off New Caledonia. These, designated carolisterols A-C (I, R = OH, R' = OH; II, R = OH, R' = O; III, R = H, R' = OH), are characterized by a polyhydroxycholanic acid moiety, in which the 24-carboxylic acid function is found as an amide deriv. of D-cysteinolic acid.File in questo prodotto:
