ChEMBL Inhibitory Activity Assay: IMAP TR-FRET Screening Express Kit (R8160) was obtained from Molecular Devices. CHK1 kinase (02-117, Carna Bio), FAM-labeled CHK1tide (R7185, Molecular Devices), and ATP were diluted with an assay buffer so that the final concentration would be 4 μg/mL, 2 μM, and 20 μM, respectively. FAM-PKAtide (R7255, Molecular Devices) and FAM-Phospho-PKAtide (R7304, Molecular Devices) were admixed after dilution, and calibration standard systems for phosphorylation levels from 0 to 100% were created. 5 μL of a compound dissolved in a 0.4% DMSO solution was added to a 384 well plate. A compound study group to which 5 μL of each of CHK1, CHK1tide, and ATP was added, and a standard group to which 20 μL of standard was added were created, and subjected to a kinase reaction for 3 hours at 30° C. Subsequently, 60 μL of Binding Reagent (80% Buffer A, 20% Buffer B, 1:600 Binding Reagent, 1:400 Tb-Donor) was added for a binding reaction for 2 hours at room temperature. SpectraMax Paradigm (Molecular Devices) was used to obtain fluorescence intensity of 520 nm or 490 nm as of 340 nm excitation. The standard was used to compute the phosphorylation level of CHK1tide, and the kinase activity was found by using the equation described below while assuming the phosphorylation level of the DMSO treated group as 100%, and the IC50 value corresponding to the concentration of the evaluated compound indicating kinase activity of 50% was calculated.
