Biological Activity

Description AZ191 is a potent and selective DYRK1B inhibitor with IC50 of 17 nM in a cell-free assay, about 5- and 110-fold selectivity over DYRK1A and DYRK2, respectively.
Targets
DYRK1B [1]
(Cell-free assay)		 DYRK1A [1]
(Cell-free assay)
17 nM 88 nM
In vitro
In vitro AZ191 selectively inhibits DYRK1B serine/threonine kinase activity with no effect on tyrosine kinase autophosphorylation. In HEK-293 cells, AZ191 also displays much greater potency for DYRK1B over DYRK1A, inhibiting CCND1 phosphorylation. In HD1B cells, AZ191 strongly inhibits the levels of the cell-cycle regulators, p21Cip1 and p27Kip1, and increases cell-cycle progression. [1]

Working concentration: mg/ml;

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.
