R547（Cat No.:I004755） is a highly potent ATP-competitive inhibitor of CDK1, CDK2, and CDK4 with Ki values of 2 nM, 3 nM, and 1 nM, respectively. It exhibits less potency against CDK7 and GSK3α/β, while also inhibiting other kinase activities. This compound’s selective inhibition of CDK1, CDK2, and CDK4 suggests its potential in regulating cell cycle progression and cell proliferation.
