Descripción

General description

A cell-permeable 3′-pyridyl oxindole compound that acts as a potent and reversible inhibitor of JAK3 (IC₅₀ = 27 nM)and displays ~16-fold greater selectivity over JAK2. Binds to the enzyme active site and prevents IL-2-induced cellular phosphorylation of JAK3 and STAT5. Inhibits IL-2-induced cell proliferation (IC₅₀ = 760 and 250 nM for mouse CTLL and human T-cells, respectively) and alleviates oxazolone-induced ear odema in mouse with an efficacy comparable to that of Dexamethasone (Cat. No. 265005).

A cell-permeable, potent, and reversible inhibitor of Janus kinase 3 (JAK3) (IC₅₀ = 27 nM). Reported to bind to the enzyme active site and prevent IL-2-induced phosphorylation of JAK3 and STAT5. Also reported to inhibit IL-2-induced cell proliferation (IC₅₀ = 760 nM for murine CTLL cells and 250 nM for human T-cells). Shown to alleviate oxazolone-induced ear edema in mice with an efficacy comparable to Dexamethasone (Cat. No. 265005) and displays ~16-fold greater selectivity over JAK2.
