In Vivo	PF-03049423 (Compound PF-5) (1-10 mg/kg; s.c.; b.i.d. for 7 days) promotes functional recovery in a rat model of severe stroke induced by permanent middle cerebral artery occlusion[1]. PF-03049423 (1.0 mg/kg b.i.d. or 0.6 mg/kg q.d. for 7 days) improves poststroke sensory–motor behavioral outcome even when the treatment is initiated 24-72 hours after occlusion[1]. Animal Model: Male Sprague-Dawley rats, middle cerebral artery occlusion (MCA-o) model[1] Dosage: 0.1, 1, or 10 mg/kg Administration: Subcutaneous injection, b.i.d. for 7 days Result: Improved functional recovery at 1 mg/kg and 10 mg/kg.
