IC50 (binding) | = 3.4 nM | BindingDB_Patents: Kinase Assay. The FLT3 inhibitory activity of the CDK4/6-FLT3 inhibitors was determined with a HTRF kinase assay. The FLT3 enzyme (GST-FLT3 fusion) was purchased from Carna Biosciences. An ULight-labeled synthetic peptide derived from human Janus kinase 1 (aa1015-1027, ULight-JAK1, PerkinElmer) was utilized as the phosphoacceptor substrate. The assay was conducted in a 384-well white OptiPlate (PerkinElmer). The 20 µL reaction mixture contained 50 nM ULight-JAK1, 116 µM ATP, 0.0385 ng/µL FLT3 and dilutions of test compounds in the kinase buffer (50 mM Hepes, pH 7.6, 1 mM EGTA, 10 mM MgCl2, 2 mM DTT, and 0.005% Tween 20). The reaction was allowed to proceed for 1 hour at room temperature and was stopped by adding 20 µL of 10 mM EDTA, 2 nM LANCE Eu-W1024 anti-phospho-tyrosine antibody in LANCE detection buffer (PerkinElmer). The plates were incubated at room temperature for 2 hours after addition of detection reagents and then read on an Envision multimode reader (PerkinElmer). | ChEMBL. | No reference |

IC50 (binding) | = 72.8 nM | BindingDB_Patents: Kinase Assay. The CDK4 and CDK1 inhibitory activity of the CDK4/6-FLT3 inhibitors was determined with a filtration kinase assay. The compounds, kinase and substrate diluted in the kinase buffer (20 mM Tris, pH7.4, 50 mM NaCl, 1 mM DTT, 0.1% BSA) were sequentially added to a 96-well Multiscreen HTS filtration plate (Millipore). The final 100 µL reaction mixture in each well contained 0.3 µg of CDK4/Cyclin D1 or CDK1/Cyclin B (Cell Signaling Technology), 1 µg of Rb fragment (aa773-928, Millipore) for the CDK4 assay or 5 µg of histone H1 for the CDK1 assay and 1 µCi of [33P]-ATP. The mixture was incubated at room temperature for 1 hour. The proteins in the reaction were then precipitated and washed with cold TCA solution using an aspiration/filtration vacuum system. The plates were dried at room temperature, and the retained radioactivity was measured by scintillation counting. | ChEMBL. | No reference |

Many chemical entities in TDR Targets come from high-throughput screenings with whole cells or tissue samples, and not all assayed compounds have been tested against a single a single target protein, probably because they get ruled out during screening process. Even if these compounds may have not been of interest in the original screening, they may come as interesting leads for other screening assays. Furthermore, we may be able to propose drug-target associations using chemical similarities and network patterns.
