| Popis: | Three steroid constituents have been isolated from the starfish Tremaster novaecaledoniae (Jangoux 1982) collected at a depth of 530 m off New Caledonia. Compounds 1 – 3 , designated as tremasterol A – C, are characterized by the presence of 3β-O-sulphated, 6α-O-phosphated and 16β-O-acetylated groupings on a steroidal skeleton. In compound 1 the monophosphate residue is further linked to 1′-glucose (1′-glucose tetracetate in 2 and 1′-glucose-6′-acetate in 3 ). |
