JAK3 Inhibitor Structural

What is JAK3 Inhibitor?

Description

WHI-P154 is a quinazoline derivative that exhibits immunosuppressive effects by selectively inhibiting JAK3 (IC50 = 1.8 μM versus IC50s > 10 μM for JAK1 and JAK2). It has been reported to inhibit additional kinases including EGFR (IC50 = 4 nM) and VEGFR as well as the non-receptor tyrosine kinases, Abl, Lck, and Src. WHI-P154 is cytotoxic to human glioblastoma cells (IC50 = 813 nM) and has been used to induce the differentiation of neuronal precursor cells.

The Uses of JAK3 Inhibitor

WHI-P154 is a potent JAK3 inhibitor with IC50 of 1.8 μM and also inhibits EGFR with IC50 of 4 nM.

The Uses of JAK3 Inhibitor

WHI-P154 can act as antileukemic agent with apoptosis inducing activity.

What are the applications of Application

WHI-P 154 is a JAK3 inhibitor which inhibits other common kinases

Biochem/physiol Actions

WHI-P154 is a specific inhibitor of JAK3 (IC50 = 1.8 μM) with no inhibitory activity against JAK1 or JAK2. WHI-P154 enhances myogenic differentiation of C2C12 mouse myoblast cells, and induces differentiation of neural progenitor cells. The compound WHI-P154 dose dependently inhibits expression of iNOS and NO production in LPS-challenged macrophages.

in vitro

kinase assays show that whi-p154 is not a specific inhibitor. besides jak3, it also inhibits many other kinases, including egfr, abl, lck, src and vegfr. whi-p154 inhibits egfr with ic50 value of 4nm. the specificity of whi-p154 has not been shown in cell-based assays either [1].
