Twenty-four asiaticacidderivatives have been synthesized and biologicallyevaluated as inhibitors of glycogenphosphorylase (GP). Within this series of compounds, asiaticacid benzyl ester (23; IC(50)=3.8 microM) exhibited more potent activity than its parent compound 1 (IC(50)=17 microM). SAR Analysis showed that asiaticacid (1) possessing a 2alpha-OH function exhibited more potent GP inhibitory
