CDK Inhibition In Vitro Assay: Selected compounds disclosed herein were tested in kinase assays by Nanosyn (Santa Clara, Calif.) to determine their inhibitory effect on these CDKs. The assays were performed using microfluidic kinase detection technology (Caliper Assay Platform). The compounds were tested in 12-point dose-response format in singlicate at Km for ATP. Specifics of each assay are as described below:CDK1/Cyclin B1: Enzyme concentration: 0.08 nM; ATP concentration: 40 μM; Incubation time: 3 hr. CDK2/Cyclin A: Enzyme concentration: 0.1 nM; ATP concentration: 50 μM; Incubation time: 3 hr. CDK2/Cyclin E: Enzyme concentration: 0.15 nM; ATP concentration: 100 μM; Incubation time: 3 hr. CDK4/Cyclin D1: Enzyme concentration: 1 nM; ATP concentration: 200 μM; Incubation time: 3 hr. CDK6/Cyclin D3: Enzyme concentration: 2 nM; ATP concentration: 300 μM; Incubation time: 3 hr. CDK9/Cyclin T1: Enzyme concentration: 5 nM; ATP concentration: 10 μM; Incubation time: 17 hr.
