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.

Mechanism of Action

Targets/IC₅₀/Ki	CDK2 ^[1] 5 nM CDK9 ^[1] 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.<sup><a class="sref" href="#s_ref">[1]</a></sup>
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).<sup><a class="sref" href="#s_ref">[1]</a></sup>
