Structure-yeast α-glucosidase inhibitory activity relationship of 9-O-berberrubine carboxylates.

ABSTRACT: Thirty-five 9-O-berberrubine carboxylate derivatives were synthesized and evaluated for yeast α-glucosidase inhibitory activity. All compounds demonstrated better inhibitory activities than the parent compounds berberine (BBR) and berberrubine (BBRB), and a positive control, acarbose. The structure-activity correlation study indicated that most of the substituents on the benzoate moiety such as methoxy, hydroxy, methylenedioxy, benzyloxy, halogen, trifluoromethyl, nitro and alkyl can contribute to the activities except multi-methoxy, fluoro and cyano. In addition, replacing benzoate with naphthoate, cinnamate, piperate or diphenylacetate also led to an increase in inhibitory activities except with phenyl acetate. 9, 26, 27, 28 and 33 exhibited the most potent α-glucosidase inhibitory activ
