Biological Activity

In vitro: 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). 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.

In vivo: AbbVie’s second JAK inhibitor in development Upadacitinib has been described as a second-generation inhibitor. Multiple-dose Phase I studies are completed in 2013. In phase I trials, Upadacitinib is found to be safe and well-tolerated up to multiple doses of 24 mg twice daily using the immediate release formulation. Upadacitinib exposure is dose proportional in the evaluated multiple dose.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
