Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	CDK4 (Cell-free assay) 10 nM CDK6 (Cell-free assay) 39 nM
In vitro	LEE011, as dual CDK4/CDK6 inhibitor, significantly inhibits the growth of 12 of 17 neuroblastoma cell lines with mean IC50 of 307 nM. The growth inhibition of neuroblastoma cell lines is primarily cytostatic and is mediated by a G1 cell-cycle arrest and cellular senescence.
In vivo	LEE011 (200 mg/kg daily, p.o.) significantly causes tumor growth delay in mice harboring the BE2C or 1643 xenografts with no weight loss or other signs of toxicity.
