Activation of the free fatty acid receptor GPR40 by (+)-curcuphenol and related synthetic compounds

Abstract

The bio-guided fractionation of an ethanol extract of Baccharis genistelloides (L) Baker, a plant that traditionally is used to treat diabetes, yielded (+)-curcuphenol (1) as agonist of GPR40, a cell surface receptor for free fatty acids. This paper describes the agonistic activity of 1 as well as of a series of semi-synthetic and synthetic analoguesThe bio-guided fractionation of an ethanol extract of Baccharis genistelloides (L) Baker, a plant that traditionally is used to treat diabetes, yielded (+)-curcuphenol (1) as agonist of GPR40, a cell surface receptor for free fatty acids.
