Ectyoplasides A-b - Unique triterpene oligoglycosides from the Caribbean sponge Ectyoplasia ferox

Two novel norlanostane triglycosides, ectyoplasides A (1) and B (2), have been isolated from the methanolic extracts of the Caribbean sponge Ectyoplasia ferox (Raspaliidae, Axinellida). Their structures have been established by extensive application of high-resolution FABMS and two- dimensional NMR techniques, supported by chemical and enzymatic degradation methods. Ectyoplasides A and B have been shown to possess identical sugar chains (composed of two β-galactose units and one α-arabinose unit), but to differ in their aglycone moieties, which possess nortriterpene skeletons with an unprecedented substitution pattern on ring A. Ectyoplasides A and B show moderate cytotoxic activity when tested in vitro towards various cell lines.

STARFISH SAPONINS. PART 8. STRUCTURE OF NODOSOSIDE, A NOVEL TYPE OF STEROIDAL GLYCOSIDE FROM THE STARFISH PROTOREASTER NODOSUS

A novel steroidal glycoside has been isolated from the starfish Protoreaster nodosus.The structure includes a 3β,5α,6β,8β,15α,24ξ-hexahydroxysteroidal moiety and a sugar moiety which is glycosidically attached at C-24 of the aglycone.
