Notes: LEE011 is a cyclin-dependent kinase (CDK) inhibitor that targets cyclin D1/CDK4 and cyclin D3/CDK6 at nanomolar concentrations.{28690,28691,28692} It inhibits retinoblastoma protein phosphorylation, which prevents CDK-mediated G1-S phase transition, arresting the cell cycle in the G1 phase, suppressing DNA synthesis, and inhibiting cancer cell growth.{28692} LEE011 has been shown to reduce proliferation in 12 of 17 human neuroblastoma-derived cell lines by inducing cytostasis (mean IC50 = 306 nM in sensitive lines).{28692}
