General description
A potent 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). It inhibits other kinases only at much higher concentrations. Also inhibits IL-2- and IL-4-dependent proliferation of CTLL cells and blocks the phosphorylation of STAT5.
