Upadacitinib

Synonyms: ABT-494

Upadacitinib is a selective JAK1 inhibitor which demonstrates activity against JAK1 (0.045 μM) and JAK2 (0.109 μM), with > 40 fold selectivity over JAK3 (2.1 μM) and 100 fold selectivity over TYK2 (4.7 μM) as compared to JAK1.

Description Upadacitinib is a selective JAK1 inhibitor which demonstrates activity against JAK1 (0.045 μM) and JAK2 (0.109 μM), with > 40 fold selectivity over JAK3 (2.1 μM) and 100 fold selectivity over TYK2 (4.7 μM) as compared to JAK1.

Upadacitinib is most potent on JAK1compared to other family members (JAK1 > JAK2 > JAK3 > TYK2). Upadacitinib 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, upadacitinib potently inhibits the JAK1 dependent cytokines IL-6, OSM, IL-2, and IFNγ, as measured by inhibition of STAT phosphorylation[1].
In Vivo
In vivo

Upadacitinib inhibits disease pathology in rat adjuvant induced arthritis[1].

It is a non-sensitive substrate for cytochrome P450, approximately 20% is eliminated, unchanged, in urine[2].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

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.
