Background:

PF-06372865 is an orally active, α2/α3/α5 subtype-selective GABAA positive allosteric modulator (PAM). PF-06372865 is a high affinity ligand at GABAA receptors containing α1/α2/α3/α5 subunits (Kis 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 epilepsy[1].

PF-06372865 (compound 34) has Ki values of 0.18 nM, 2.9 nM, 1.1 nM, 18 nM for human GABAA α1β3γ2, α2β2γ2, α3β3γ2, α5β2γ2 and 0.34 nM, 4.58 nM for rat GABAA α1β3γ2, α2β2γ2[1].

PF-06372865 (compound 34; 3, 10 mg/kg; orally; single dose) significantly increases the paw withdrawal threshold (PWT) in chronic constriction injury (CCI) animals[1]. 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)[1]. 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)[1]. PF-06372865 has a T1/2 of 1.1 hours, a Clp of 22 mL/min/kg, and a Vss of 2.1 L/kg for rats[1]. PF-06372865 has a T1/2 of 0.9 hours, a Clp of 29 mL/min/kg, and a Vss of 3.4 L/kg for dogs[1].
