Bruton tyrosine kinase/Tyrosine-protein kinase BTK in Human (target type: SINGLE PROTEIN) [ChEMBL: CHEMBL5251] [GtoPdb: 1948] [UniProtKB: Q06187] | ||||||||
ChEMBL | Enzymatic Activity Assay: A Caliper-based kinase assay (Caliper Life Sciences, Hopkinton, Mass.) was used to measure inhibition of Btk kinase activity of a compound of Formula (IA), (I′) or (I). Serial dilutions of test compounds were incubated with human recombinant Btk (2 nM), ATP (40 μM) and a phosphoacceptor peptide substrate FAM-GEEPLYWSFPAKKK-NH2 (1 μM) at room temperature for 3 h. The reaction was then terminated with EDTA, final concentration 20 mM and the phosphorylated reaction product was quantified on a Caliper Desktop Profiler (Caliper LabChip 3000). Percent inhibition was calculated for each compound dilution and the concentration that produced 50% inhibition was calculated. | B | 8.7 | pIC50 | 2 | nM | IC50 | US-9090621-B2.
