Synthesis of cholestane glycosides bearing OSW-1 disaccharide or its 1→4-linked analogue and their antitumor activities
摘要:
For further structure-activity relationship (SAR) research of OSW saponins, a cholestane glycoside, namely 3 beta, 16 beta, 26-trihydroxycholest-5-en-22-one 16-O-(2-O-4-methoxybenzoyl-beta-D-xylopyranosyl)-(1 -> 3)-2-O- acetyl-alpha-L-arabinopyranoside (1) together with two 1 -> 4-linked disaccharide analogues (2 and 3) were synthesized. Their cytotoxic activities were evaluated by the standard MTT assay. Compound 1 showed potent cytotoxicity against five types of human tumor cells, with IC50 ranging between 1.3 and 73 nM.
