A pyridazine series of alpha2/alpha3 subtype selective GABA A agonists for the treatment of anxiety

J Med Chem. 2006 Apr 20;49(8):2600-10. doi: 10.1021/jm051144x.

Abstract

The development of a series of GABA(A) alpha2/alpha3 subtype selective pyridazine based benzodiazepine site agonists as anxiolytic agents with reduced sedative/ataxic potential is described, including the discovery of 16, a remarkably alpha3-selective compound ideal for in vivo study. These ligands are antagonists at the alpha1 subtype, with good CNS penetration and receptor occupancy, and excellent oral bioavailability.
