title: Synthesis of glucoconjugates of oleanolic acid as inhibitors of glycogen phosphorylase.
abstract: Synthesis and biological evaluation of glucoconjugates of oleanolic acid, linked by either a triazole moiety or an ester function, as novel inhibitors of glycogen phosphorylase have been described. Several triterpene-glycoside conjugates exhibited moderate-to-good inhibitory activity against rabbit muscle GPa. Compound 12 showed the best inhibition with an IC(50) value of 1.14 microM. Structure-activity relationship (SAR) analysis of these inhibitors is also discussed. Possible binding modes of compound 12 were explored by molecular docking simulations.
