Concise syntheses of selective inhibitors against α-1,3-galactosyltransferase

Abstract

Several iminosugar-based uridine diphosphate galactose (UDP-Gal) mimetics 1–4 including D- and L-epimers were designed and synthesized by concise routes, and these synthetic compounds were evaluated for the inhibition of α-1,3- and β-1,4-galactosyltransferases in vitro. The experimental data demonstrated that L-epimer 2 displayed the strongest inhibitory activity with moderate selectivity against α-1,3-galactosyltransferase.
