Upadacitinib (ABT-494) is a potent, orally active and selective Janus kinase 1 (JAK1) inhibitor (IC50=43 nM). Upadacitinib (ABT-494) displays approximately 74 fold selective for JAK1 over JAK2 (200 nM) in cellular assays dependent on specific, relevant cytokines. Upadacitinib (ABT-494) can be used for several autoimmune disorders research.
In biochemical assays, Upadacitinib is 74-fold more selective for JAK-1 than for JAK-2 (which is involved in erythropoiesis) and 58-fold more selective for JAK-1 than for JAK-3 (which is involved in immunosurveillance)[1]. The enhanced selectivity of Upadacitinib for JAK-1 over JAK-2 and JAK-3 may offer an improved benefit–risk profile in patients with RA range[2].
Upadacitinib (0.1-10 mg/kg
oral gavage
twice a day for 10 days) demonstrates efficacy in rat arthritis models[3].
