NCIt definition : An orally available cyclin-dependent kinase (CDK) inhibitor with potential antineoplastic
activity. Palbociclib selectively inhibits cyclin-dependent kinase 4 (CDK4) and 6
(CDK6), thereby inhibiting retinoblastoma (Rb) protein phosphorylation early in the
G1 phase leading to cell cycle arrest. This suppresses DNA replication and decreases
tumor cell proliferation. CDK4 and 6 are serine/threonine kinases that are upregulated
in many tumor cell types and play a key role in the regulation of cell cycle progression.;
