Synthesis and Biological Evaluation of Arjunolic Acid, Bayogenin, Hederagonic Acid and 4-Epi-hederagonic Acid as Glycogen Phosphorylase Inhibitors  To study glycogen phosphorylase inhibitory activity of natural pentacyclic triterpenes bearing 23-hydroxy or 24-hydroxy. 

METHODS AND RESULTS:

Arjunolic acid, Bayogenin, hederagonic acid and 4-epi-hederagonic acid were synthesized from oleanolic acid as the starting material and biologically evaluated as glycogen phosphorylase inhibitors. Arjunolic acid, Bayogenin, hederagonic acid and 4-epi-hederagonic acid were successfully semi-synthesized by multiple steps. The synthesis of arjunolic acid was via 11 steps in about 10% overall yield, and Bayogenin via 14 steps in about 12% overall yield. Biological evaluation indicated that arjunolic acid, Bayogenin, hederagonic acid and 4-epi-hederagonic acid showed moderate potency of glycogen phosphorylase inhibition with IC50 of 53-103 μmol/L. 

CONCLUSIONS:

Arjunolic acid, Bayogenin, hederagonic acid and 4-epi-hederagonic acid are gly-cogen phosphorylase inhibitors with moderate potency. Insert of 23-hydroxy or 24-hydroxy to oleanane skeleton has a tendency to be unfavorable to GP inhibition.
