General description

A potent, cell-permeable, reversible, and ATP-competitive inhibitor of Janus protein tyrosine kinases (JAKs). Displays potent inhibitory activity against JAK1 (IC50 = 15 nM for murine JAK1), JAK2 (IC50 = 1 nM), JAK3 (Ki = 5 nM), and Tyk2 (IC50 = 1 nM). Inhibits other kinases at much higher concentrations. Shown to inhibit IL2- and IL4-dependent proliferation of CTLL cells and block the phosphorylation of STAT5, and further induce growth inhibition of multiple myeloma cells expressing activated JAKs and STAT3, unlike AG 490 (Cat. No. 658401).
