描述 | Tofacitinib Citrate is the citrate form of Tofacitinib. Tofacitinib is an ATP-competed inhibitor of JAK with IC50 values of 3.2±1.4 nM, 4.1±0.4 nM, 1.6±0.2 nM, 34.0±6.0 nM for JAK1, JAK2, JAK3 and TYK2 in in vitro enzyme assays. It competes with ATP for binding to the active site of the kinase domain of JAKs with Ki values of 0.68 ± 0.12 nM (JAK1), 0.99 ± 0.04 nM (JAK2), 0.24 ± 0.02 nM (JAK3) and 4.39 ± 0.27 nM (TYK2). Tofacitinib potently inhibits multiple cytokine activated JAK/STAT signaling pathways in normal human, mouse or rat whole blood with IC50s below 200 nM. Selectivity assessed in mouse and rat whole blood shows that tofacitinib appears to be more potently to JAK1 and JAK3. In cell assays, tofacitinib inhibits human total myeloid and CFU-G colony formation with IC50s of 0.87 and 0.93 μM. In AIA rats, tofacitinib treatment can decrease paw volume and disease-elevated neutrophil count to normal range compared to vehicle treated control rats. Tofacitinib treatment also dose-dependently decreased both IL-17 and IL-6 of the AIA-induced increase compared to control levels with an approximately 80% inhibition. It significantly inhibits the AIA-induced increase in maturing myeloid cells by approximately 50% at the 10 mg/kg dose[3]. Tofacitinib has been approved by the U.S. Food and Drug Administration and European Medicines Agency for the treatment of rheumatoid arthritis (RA), psoriatic arthritis and ulcerative colitis[1]. |
