Discovery of a novel potent GABA(B) receptor agonist

Bioorg Med Chem Lett. 2011 Nov 1;21(21):6582-5. doi: 10.1016/j.bmcl.2011.08.006. Epub 2011 Aug 17.

Abstract

Structure-activity studies have led to a discovery of 3-(4-pyridyl)methyl ether derivative 9d that has 25- to 50-fold greater functional potency than R-baclofen at human and rodent GABA(B) receptors in vitro. Mouse hypothermia studies confirm that this compound crosses the blood-brain barrier and is approximately 50-fold more potent after systemic administration.
