产品介绍:
Oclacitinib maleate (PF-03394197 maleate) 是一种新型 JAK 抑制剂。Oclacitinib maleate (PF-03394197 maleate) 抑制 JAK1 最有效,IC50 为 10 nM。
靶点作用:
JAK1
10 nM (IC50)
JAK2

Tyk2
84 nM (IC50)
JAK3
99 nM (IC50)
体内作用原理:
Scratching bouts at the high dose in the Oclacitinib group are significantly less than in the vehicle-only group (P<0.01)[2]. Client-owned dogs (n=436) with moderate to severe owner-assessed pruritus and a presumptive diagnosis of allergic dermatitis are enrolled. Dogs are randomized to either Oclacitinib at 0.4-0.6 mg/kg orally twice daily or an excipient-matched placebo. An enhanced 10 cm visual analog scale (VAS) is used to assess the severity of pruritus from day 0 to 7 and to assess the severity of dermatitis on days 0 and 7. Dogs can remain on the study for 28 days. Oclacitinib produces a rapid onset of efficacy within 24 h[3].
