Synthesis of steroidal glycosides bearing the disaccharide moiety of OSW-1 and their antitumor activities

摘要

Nine glycosides bearing the disaccharide of OSW-1,namely 2-O-(4-methoxybenzoyl)-#beta#-D-xylopyranosyl-(1->3)-2-O-acetyl-#alpha#-L-arabinopyranosides,were synthesized,and their antitumor activities were tested.
