Synthesis and biological activities of octyl 2,3-di-O-sulfo-alpha-L-fucopyranosyl-(1-->3)-2-O-sulfo-alpha-L-fucopyranosyl-(1-->4)-2,3-di-O-sulfo-alpha-L-fucopyranosyl-(1-->3)-2-O-sulfo-alpha-L-fucopyranosyl-(1-->4)-2,3-di-O-sulfo-beta-L-fucopyranoside.
Octyl 2,3-di-O-sulfo-alpha-L-fucopyranosyl-(1-->3)-2-O-sulfo-alpha-L-fucopyranosyl-(1-->4)-2,3-di-O-sulfo-alpha-L-fucopyranosyl-(1-->3)-2-O-sulfo-alpha-L-fucopyranosyl-(1-->4)-2,3-di-O-sulfo-beta-L-fucopyranoside, a fucosyl pentasaccharide with a regular structure resembling the repeating unit of a natural sulfated fucan, was chemically synthesized using a convergent '2+3' strategy. Regioselective 3-O-silylation of beta-thiofucopyranoside and AgOTf-catalyzed glycosylation of the protected glycosyl trichloroacetimidate facilitated a one-pot trisaccharide synthesis. The synthesized target compound showed good antitumor activity in vivo, and promising anticoagulant activity in vitro.
