Tofacitinib, also named CP-690550 orTasocitinib, is a novel oral Janus kinase inhibitor which is being used as a targeted immune-modulator. It primarily inhibits signaling through heterodimeric receptors associated with JAK3, JAK1, or both of them, with functional selectivity over JAK2-paired receptors. Inhibition of JAK1 and JAK3 by tofacitinib blocks signaling for several cytokines, including interleukins 2, 4, 7, 9, 15, and 21. These cytokines are integral to lymphocyte activation, function, and proliferation. Tofacitinib is also an inhibitor of STAT molecules. Recent efforts to investigate the mechanism of action have shown that tofacitinib interacts with multiple JAKs and presumably other kinases
