Derivatives of 1,4-bis(3-hydroxycarbonyl-4-hydroxyl)styrylbenzene as PTP1B inhibitors with hypoglycemic activity.


PMID 18722777

Abstract

Disalicylic acid derivatives with stilbene and bis-styrylbenzene skeleton were synthesized as PTP1B inhibitors. The most potent in this series exhibited a submicromolar IC(50) value. One of the compounds 7b was tested in an animal model for its efficacy as an anti-diabetic or an anti-obesity agent. In feeding compound 7b to diet-induced obese mice, no significant differences in weight gain and food consumption were observed between the drug-treated and the obese control mice. However, 7b significantly lowered the fasting glucose level and improved the glucose tolerance in the obesity-induced diabetic mice.
