Biological Activity:

CP-690550 is a potent and selective JAK inhibitor currently in clinical trials for rheumatoid arthritis (RA) and other autoimmune disease indications.  It inhibits recombinant human JAK1 (IC50 ~ 3.2 nM), JAK2 (IC50 ~4.1 nM), and JAK3 (IC50 ~1.6 nM). In cellular assays CP-690550 showed potent effects in the IL-2 blast proliferation assay (IC50 ~11 nM, mediated via JAK1 and JAK3) and HU03 cellular specificity assay (IC50 ~324 nM, mediated via JAK2), but has relatively minimal effects on general cell growth (>10 µM activity in the HFF assay).


How to Use:

 

  • In vitro:  CP-690550 was used at 0.05-1 µM concentration in a panel of in vitro assays.
  • In vivo: CP-690550 was orally dosed to rats at 10-50 mg/kg once or twice per day.
