JAK3 INHIBITOR I Usage And Synthesis

Description

WHI-P131 (202475-60-3) is a JAK3 inhibitor.?Inhibits human glioblastoma cell adhesion and invasion.1 Increases survival in a mouse ALS model.2 Delays or prevents autoimmune type 1 diabetes in NOD mice.3 Exhibits potent anti-inflammatory activity in mouse models of peritonitis, colitis, cellulitis and systemic inflammatory response syndrome.4 Displays protective effects against myocardial ischemia and reperfusion injury in mouse models.5

Uses

Janex 1 is a Janus tyrosine kinase 3 (JAK3) inhibitor. Inhibition of JAK3 has been shown to exhibit protective action against the development of T1D in non-obese diabetic (NOD) mice. Janex 1 has been shown to suppresses proliferation of short-term cultured NOD CD4+ T cells through induction of apoptosis, while promoting survival of a particular population of long-term cultured cells. It ameliorates the expression of TNF-α-induced cell adhesion molecules and improves myocardial vascular permeability.

in vivo

JANEX-1 is administered at doses ranging from 5 to 100 mg/kg. Evaluation of CPK activity revealed a dose-response curve with an effective dose 50 (ED50) value of 7.44 mg/kg. Mice receiving JANEX-1 displayed significantly reduced CPK and LDH levels. In addition, the infarct size of JANEX-1-treated mice (30.16±2.79%) is significantly decreased when compared with I/R-operated mice (65.64±3.76%)[2]. JANEX-1 (WHI-P131) is absorbed rapidly, and the time to reach the maximum plasma JANEX-1 concentration (tmax) is 24.7±1.7 min. JANEX-1 is rapidly eliminated with an elimination half-life of 45.6±5.5 min. Although the predicted maximum plasma JANEX-1 concentration is 10.5 ± 0.8 μM, which is only half of the Cmax following i.v. administration of the same bolus dose, the i.p. bioavailability is 94.6% and the systemic exposure levels (i.e., AUC) are very similar to those observed after i.v. injection (17.1±2.2 μM h versus 18.1±1.2 μM h)[3].
