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	CDK9 <0.004 μM
In vitro	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). In human cancer cell line panel screens, this compound 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).
In vivo	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.
