Details:
Tofacitinib (Tasocitinib, CP-690550) is a novel, small molecule inhibitor of JAK3 with an IC50 with 1 nM, and exhibits rather indiscriminate activity towards JAK1 (IC50 = 112 nM) and JAK2 (IC50 = 20 nM). CP 690550 is an inhibitor of the enzyme Janus kinase 3 (JAK3), which means that it interferes with the JAK-STAT signaling pathway that transmits information outside the cell into the cell nucleus, influencing DNA transcription. Recently it has been shown in a murine model of established arthritis, tofacitinib rapidly improved disease by inhibiting the production of inflammatory mediators and suppressing STAT1-dependent genes in joint tissue. This efficacy in this disease model correlated with the inhibition of both JAK1 and 3 signaling pathways, suggesting that tofacitinib may exert therapeutic benefit via pathways that are not exclusive to inhibition of JAK3.
