JAK3 Inhibitor VIII, NSC114792-Calbiochem

C₂₆H₃₂N₄O₂S

464.62

A cell-permeable steroidal-purinethione compound that targets JAK3 kinase domain and selectively inhibits JAK3, but not JAK1, JAK2, or TYK2, activity in cell-free immuncomplex kinase assays, and effectively blocks the constitutive Jak3 and STAT5 phosphorylations (complete inhibition at 10 µM) in BaF3-JAK3^V674A and BLNK^-/- BKO84 culltures. Shown to prevent the JAK3-dependent survival of L540, BaF3-JAK3^WT, BaF3-JAK3^V674A, and BLNK^-/- BKO84 cells in a time- and dose-dependent manner (by 40%, 50%, 57%, and 85%, respectively, after 72 h incubation with 20 µM inhibitor), while exhibiting no effect against the JAK3-independent growth in DU145, HDLM-2, and MDA-MB-468 cultures.
