Synthesis and antitumor activity of icogenin and its analogue.
Natural saponin icogenin, namely 25(S)-22-O-methyl-furost-5-en-3beta,26-dio-3-O-alpha-L-rhamnopyranosyl-(1-->2)-[beta-D-glucopyranosyl-(1-->3)]-beta-D-glucopyranoside, and one of its analogues, 25(S)-22-O-methyl-furost-5-en-3beta,26-dio-3-O-alpha-L-rhamnopyranosyl-(1-->2)-[beta-D-glucopyranosyl-(1-->3)]-alpha-D-glucopyranoside, were first synthesized via line strategy and convergent approach, respectively. It was observed that icogenin and its analogue show potent antitumor activity in vitro.
