PF-06372865 (C007B-386734)

PF-06372865 is an orally active, α2/α3/α5 subtype-selective GABA A positive allosteric modulator (PAM). PF-06372865 is a high affinity ligand at GABA A receptors containing α1/α2/α3/α5 subunits ( K i s of 2.9 nM, 21 nM, 134 nM for α2, α1 PAM, α2 PAM, respectively), with low affinity for α4/α6 subunits. PF-06372865 can across the blood-brain barrier (BBB). PF-06372865 has anxiolytic activity and has the potential for epilepsyIn VitroPF-06372865 (compound 34) has K i values of 0.18 nM, 2.9 nM, 1.1 nM, 18 nM for human GABA A α1β3γ2, α2β2γ2, α3β3γ2, α5β2γ2 and 0.34 nM, 4.58 nM for rat GABA A α1β3γ2, α2β2γ2.

PF-06372865 (0.3, 3, 10 mg/kg for mouse and 1, 3, 10 mg/kg for rat; orally) exhibits efficacy in two models of epilepsy, PTZ induced seizures (mouse), and amygdala kindling (rat) . PF-06372865 (0.1, 0.32, 1, 3.2 and 10 mg/kg; orally) has anxiolytic activity at 3.2 and 10 mg/kg in elevated plus maze (male C57Bl/6 mice) . PF-06372865 has a T 1/2 of 1.1 hours, a Cl p of 22 mL/min/kg, and a V ss of 2.1 L/kg for rats . PF-06372865 has a T 1/2 of 0.9 hours, a Cl p of 29 mL/min/kg, and a V ss of 3.4 L/kg for dogs .
