CKIα inhibitor A86 is a groundbreaking pan-specific inhibitor targeting Casein Kinase I (CSNK1), with a remarkable binding affinity (Kd=1-10 nM) and a specific Kd of 9.8 nM for CKIα. Beyond its primary activity, this compound also demonstrates dual inhibitory effects on the transcriptional kinases CDK7 and CDK9. Notably, it exhibits minimal to no inhibition against CDK8, CDK13, CDK11a, CDK11b, and CDK19, highlighting its selective pharmacological profile.
