Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O	4.0mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 80 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	5% DMSO 1 95% Corn oil	2.0mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 40 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description

Fadraciclib (CYC065) is a novel, orally available ATP-competitive inhibitor of CDK2/CDK9 kinases with IC50 of 5 nM and 26 nM, respectively.

Targets

CDK2 ^[1]	CDK9 ^[1]
5 nM	26 nM

In vitro

Fadraciclib effectively downregulates pro-survival and leukemogenic proteins and that short pulse treatment is sufficient to substantially decrease cell viability of the majority of AML cell lines tested via apoptotic induction.<a class="sref" href="#s_ref">[1]</a>

In vivo

Fadraciclib shows potent anti-leukemic activity in two subcutaneous xenograft models EOL-1 (with MLL-PTD) and HL60 (non MLLr/MLL-PTD AML with MYC amplification).<a class="sref" href="#s_ref">[1]</a>

Protocol (from reference)

Cell Assay:^{<sup><a class="sref" href="#s_ref">[2]</a></sup>}	Cell lines AML cell lines Concentrations 1 μM Incubation Time 72 h Method Half-maximal inhibitory concentration (IC50) of AML cell lines treated with fadraciclib for up to 72 h was established using 7-Hydroxy-3H-phenoxazin-3-one-10-oxide sodium salt resazurin assay according to manufacturer’s instructions. IC50 were calculated using GraphPad Prism 8 software (GraphPad Software).
