Description AZD4573 is a potent inhibitor of CDK9 (IC50 of <0.004 μM) with fast-off binding kinetics (t1/2 = 16 min) and high selectivity versus other kinases, including other CDK family kinases.

Short-term treatment with AZD4573 leads to a rapid dose- and time-dependent decrease in cellular pSer2-RNAPII, resulting in activation of caspase 3 and cell apoptosis in a broad range of haematological cancer cell lines (e.g. caspase activation EC50 0.0137 μM in an acute myeloid leukemia model MV4-11)[1].

In human cancer cell line panel screens, AZD4573 demonstrates the ability to induce rapid caspase activation (6h) and loss of viability (24h) across a diverse set of hematological cancers (median caspase EC50 = 30 nM, GI50 = 11 nM) but with minimal effect on solid tumors (median EC50 & GI50 >30 μM)[2].

AZD4573 exhibits a short half-life in multiple preclinical species (less than one hour in rat, dog and monkey) and good solubility for intravenous administration[1].

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.
