Abstract

We herein describe the synthesis and positive modulatory activities of a small library of flavan-3-ol derivatives on alpha(1)beta(2)gamma(2L) GABA(A) receptors. Structure-activity relationships of various substituents on the A, B and C rings were evaluated in a functional electrophysiological assay. A trans configuration and a 3-acetoxy moiety are essential for activity. Substitution of the B ring appears to be well tolerated, with substituents on the A ring playing a major role in determining activity.
