Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

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.
