Background

Palbociclib, also known as PD 0332991, is a potent and selective inhibitor of cyclin-dependent kinase 4 (Cdk4, IC₅₀ = 11nM) and cyclin-dependent kinase 6 (Cdk6, IC₅₀ = 16nM). Phosphorylation of retinoblastoma protein (Rb) by Cdk4 and Cdk6 leads to G₁-S phase advancement, which is an important checkpoint for cell division (1). This regulation of the cell cycle makes the activation and inhibition of Cdk4 and Cdk6 highly researched. Palbociclib has been shown to arrest the proliferation of 5T33MM tumor cells in vivo and ex vivo, and treatment with the compound has increased the survival rate of 5T33MM diseased mice (2).
