Isolation and Structure Elucidation of GM4-Type Gangliosides from the Okinawan Starfish Protoreaster nodosus
Three new ganglioside molecular species, termed PNG-1, PNG-2A, and PNG-2B were isolated from pyloric caeca of the starfish Protoreaster nodosus. Their structures were elucidated using a combination of spectroscopic and chemical methods, and characterized as 1-O-[8-O-methyl-N-acetyl-α-neuraminosyl-(2→3)-β-galactopyranosyl]-ceramide for PNG-1, 1-O-[β-galactofuranosyl-(1→...
متن کاملIdentification of sixteen new galactocerebrosides from the starfish Protoreaster nodosus.
Twenty-one galactocerebrosides (1-21), including sixteen new compounds (3-7, 9-17, 19, 21), were identified from a cerebroside molecular species obtained from the chloroform/methanol extract of pyloric caeca dissected from the starfish Protoreaster nodosus. The structures of these galactocerebrosides were determined on the basis of chemical and spectroscopic evidences. Especially, one-pot GC-MS...
