Synthesis, conformational analysis and SAR research of OSW-1 analogues

A series of novel OSW-1 analogues were synthesized by coupling disaccharides (2-O-4-methoxylbenzoyl-β-D-xylopyranosyl-(1→3)-2-O-acetyl-α-L-arabinopyranosyl) or (2-O-4-(E)-cinnamoyl-β-D-xylopyranosyl-(1→3)-2-O-acetyl-α-L-arabinopyranosyl) and their 1→4 lin

Study on the synthesis of regio- and stereoisomers of the disaccharide unit of the OSW-1 saponin

A convenient method for the preparation of the OSW-1 disaccharide unit was developed and used for the synthesis of its regio- and stereoisomers. The corresponding allyl and 1-propenyl xylopyranosides and arabinopyranosides were used as starting materials.

First total synthesis of an exceptionally potent antitumor saponin, OSW- 1

OSW-1 (1), an acylated disaccharide cholestane saponin from Ornithogalum saudersiae with exceptionally potent antitumor activity, was first synthesized from commercially available dehydroisoandrosterone, L-arabinose, and D-xylose in total 27 steps with the longest linear sequence of 14 steps and in 6% yield.
