Abstract

The known compound bakuchiol (1) was isolated from an extract of Otholobium pubescens (Fabaceae) by bioassay-guided fractionation using the db/db mouse model for tyep 2 diabets. Oral administration of 1 reduced blood glucose levels in a dose-dependent fashion in db/db mice and did not display a hypoglycemic effect when tested in lean mice at 250 mg/kg q.d. Compound 1 was further evaluated in a new rodent model for type 2 diabetes, the fat-fed, streptozotocin (STZ)-treated rat. In this model, an oral dose of 1 at 150 mg/kg q.d. significantly lowered plasma glucose and triglyceride levels.
