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	CDK2 ^[1] (Cell-free assay) 3.27 nM CDK9 ^[1] (Cell-free assay) 5.78 nM CDK1 ^[1] (Cell-free assay) 8.17 nM CDK4 ^[1] (Cell-free assay) 8.18 nM
In vitro	CDKI-73 induces cancer cells undergoing apoptosis through transcriptional downregulation of anti-apoptotic proteins Bcl-2, Mcl-1 and XIAP by majorly targeting CDK9. Contrastively, this compound is relatively low toxic to the bone marrow cells of healthy donors.^[2]
In vivo	CDKI-73 is orally bioavailable, highly efficacious against MLL-AML MV4–11 xenografts and downregulates anti-apoptotic proteins by targeting CDK9 in vivo.^[2]
