A Janus kinase inhibitor, also known as JAK inhibitor or jakinib,[1] is a type of immune modulating medication, which inhibits the activity of one or more of the Janus kinase family of enzymes (JAK1, JAK2, JAK3, TYK2), thereby interfering with the JAK-STAT signaling pathway in lymphocytes.

JAK inhibitors are used in the treatment of some cancers and inflammatory diseases[1][2] such as rheumatoid arthritis[3] and various skin conditions.[4] A Janus kinase 3 inhibitor is attractive as a possible treatment of various autoimmune diseases since its function is mainly restricted to lymphocytes. JAK inhibitors can suppress the signaling of pro-inflammatory cytokines. Pro-inflammatory cytokines are major contributors to the cause of an over active immune system, resulting in inflammation and pain. JAK inhibitors have the ability to slow down this over activity by the suppression of the intracellular signaling.[5]
