Background:
CP 690,550-d3is intended for use as an internal standard for the quantification of CP 690,550 by GC- or LC-MS. CP 690,550 is a potent, cell-permeable inhibitor of all JAK isoforms (IC50s = 6.1, 12, and 8 nM for JAK1, JAK2, and JAK3, respectively).1It is selective for JAK1-3 over ROCK-II and Lck (IC50s = 3,400 and 3,870 nM, respectively) as well as 28 additional kinases in enzyme assays (IC50s = >10,000 nM). It inhibits IL-2-mediated phosphorylation of JAK3 and STAT5 when used at a concentration of 30 ng/ml.2CP 690,550 prevents rejection and prolongs survival in murine and cynomolgus monkey models of heterotopic heart and kidney transplantation, respectively. Formulations containing CP 690,550 have been used in the prevention of organ allograft rejection as well as in the treatment of the inflammatory or autoimmune components of a host of diseases, including rheumatoid arthritis and ulcerative colitis.2,3,4,5
