バックグラウンド

WHI-P131 is a potent and selective inhibitor of Janus kinase 3 (Jak3) (IC50 = 78 μM) and glioblastoma cell adhesion and migration (1,2). This novel quinazoline derivative inhibits the enzymatic activity of constitutively active Jak3 without affecting Jak1, Jak2, or other family tyrosine kinases (1). WHI-P131 has also been shown to inhibit thrombin-induced tyrosine phosphorylation of Stat1 and Stat3. These properties make this compound useful when studying different diseases such as acute lymphoblastic leukemia, glioblastoma multiforme, and thromboembolism (1-3).
