BAY 1143572 is a potent and highly selective CDK9 inhibitor (IC50 CDK9/CycT1: 13 nM, ratio of IC50 values CDK2/CDK9: 100). Outside the CDK family, submicromolar inhibitory activity was only recorded against GSK3 kinase (IC50 GSK3α: 45 nM, GSK3β: 87 nM). BAY 1143572 demonstrates antiproliferative activity against HeLa cells (IC50 = 920 nM) and MOLM-13 cells (IC50 = 310 nM). It also demonstrates improved Caco-2 permeability and a decreased efflux ratio (PappA→B: 35 nm/s, ER: 6) relative to lead compound BAY‐958 (PappA→B: 22 nm/s, ER: 15)[1].

In an in vivo pharmacokinetic study in rats, BAY 1143572 showed low blood clearance (CLb 1.1 L/h/kg). The volumes of distribution (Vss) of BAY 1143572 is 1.0 L/kg. BAY 1143572 shows significantly improved oral bioavailability of 54 %. The blood/plasma ratios is about 1. It does not show significant inhibition of cytochrome P450 activity, with IC50 values >20 μM[1]. The administration of BAY 1143572 in immunocompromized NOD/Shi-scid/IL-2Rγ null (NOG) mice xenografted with patient-derived ATL cells greatly reduced the infiltration of ATL cells into organs, such as liver and bone marrow. Decreased human soluble IL2R levels in serum were also observed, which indicated a reduction of ATL tumor burden[2].

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.
