Description

WHI-P154 is a JAK3 inhibitor with IC50 = 1.8 microM. WHI-P154 displays no activity at JAK1 or JAK2. WHI-P154 also Inhibits STAT1 activation, iNOS expression and NO production in macrophages in vitro . Also inhibits other common kinases including EGFR (IC50 = 4 nM), Src, Abl, VEGFR, MAPK and PI 3-K and induces apoptosis in human glioblastoma cell lines (IC50 = 158 microM).

How to use

In Vitro:

WHI-P154 is a potent EGFR inhibitor, and also modestly blocks JAK3, with IC50s of 4 nM and 1.8 μM, respectively[1]. WHI-P154 significantly enhances the sensitivity of ABCG2-overexpressing cells to its substrates. WHI-P154 (4 μM) moderately sensitizes ABCB1-overexpressing KB-C2 cells to its substrates whereas shows no sensitizing effect on ABCC1-, ABCC2 or ABCC10-mediated drug resistance. Moreover, WHI-P154 (4 μM) causes a significant increase in the intracellular accumulation of [3H]-mitoxantrone in ABCG2-overexpressing cells. WHI-P154 alters the expression levels rather than the localization of the ABCG2 protein in ABCG2-overexpressing cells.
