Terpenoids. III: Synthesis and biological evaluation of 23-hydroxybetulinic acid derivatives as novel inhibitors of glycogen phosphorylase

Bioorg Med Chem Lett. 2009 Dec 15;19(24):6966-9. doi: 10.1016/j.bmcl.2009.10.055. Epub 2009 Nov 2.

Abstract

A series of 23-hydroxybetulinic acid derivatives were prepared and tested in vitro as a new class of inhibitors of glycogen phosphorylase (GP). Within this series of compounds, 12b (IC(50)=3.5 microM) is the most potent GPa inhibitor. The preliminary SAR results of the 23-hydroxybetulinic acid derivatives are discussed.
