AbstractA series of ring-A fused heterocycles of lupane, oleanane, ursane and dammarane triterpenoids were synthesized and evaluated for their inhibitory activity against α-glucosidase. An influence of the different types of triterpenoids with indole and pyrazine cycles on the activity was revealed. Among them, 2,3-indolo-lup-20(29)-en-28-oic acid with an IC50 of 1.8 µM was the most active compound
