Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	JAK1 ^[1] (Cell-free assay) 45 nM JAK2 ^[1] (Cell-free assay) 109 nM
In vitro	Upadacitinib is most potent on JAK1compared to other family members (JAK1 > JAK2 > JAK3 > TYK2). This compound demonstrates selectivity across a broad panel of 70+ kinases, with only Rock1 and Rock2 demonstrating IC50 values below 1 μM. Consistent with the Ba/F3 cellular data, it potently inhibits the JAK1 dependent cytokines IL-6, OSM, IL-2, and IFNγ, as measured by inhibition of STAT phosphorylation^[1].
In vivo	Upadacitinib inhibits disease pathology in rat adjuvant induced arthritis^[1]. This compound is a non-sensitive substrate for cytochrome P450, approximately 20% is eliminated, unchanged, in urine^[2].
