PF-04859989 hydrochloride_product_DataBase

Bioactivity	PF-04859989 hydrochloride is a brain-penetrant, irreversible kynurenine aminotransferase (KAT) II inhibitor with IC50s of 23 and 263 nM for hKAT II and rKAT II. PF-04859989 hydrochloride is selective for KAT II over human KAT I, KAT III, and KAT IV (IC50s of 22, 11, and >50 μM, respectively)[1].
In Vivo	In vivo pharmacokinetic and efficacy studies in rat show that PF-04859989 is a brain-penetrant, irreversible inhibitor and is capable of reducing brain kynurenic acid by 50% at a dose of 10 mg/kg (sc)[1]. Rats receiving PF-04859989 (5 mg/kg; i.p.) exhibited a significantly lower number of spontaneously active DA neurons pertrack[1]. Animal Model:
