Biochem/physiol Actions

PF-00080665 (Palbociclib; PD 0332991) is an orally active and highly specific inhibitor against cyclin-dependent kinase 4 & 6 (IC50 = 9, 11, 15 nM, respectively, using CDK4/cycD3, CDK4/cycD1, CDK6/cycD2; IC50 >10 μM against 36 other kinases) that potently suppresses Cdk4/6-dependent cellular Rb phosphorylation (IC50 = 66 nM/pSer780 & 63 nM/pSer795; MDA-MB-435). PF-00080665 exhibits selective antiproliferation activity against Rb-positive human breast/colon/lung/leukemia cancer cultures (IC50 = 40-400 nM; IC50 >3 μM/Rb-negative MDA-MB-468 & H2009) and displays in vivo efficacy against various advanced stage human tumor xenografts in mice (12.5-150 mg/kg/day p.o.).
