Tambiciclib (GFH009, JSH-009) dimaleate is an orally active, highly potent and selective CDK9 inhibitor (IC₅₀ = 1 nM), demonstrating >200-fold selectivity over other CDKs, >100-fold selectivity over DYRK1A/B, and excellent selectivity over 468 kinases/mutants. Tambiciclib dimaleate demonstrates potent in vitro and in vivo antileukemic efficacy in acute myeloid leukemia (AML) mouse models by inhibiting RNA Pol II phosphorylation, downregulating MCL1 and MYC, and inducing apoptosis. Tambiciclib dimaleate can be used for AML research.

In Vitro

Tambiciclib (JSH009) dimaleate (72 h) potently inhibits the growth of diverse AML cell lines and patient-derived primary cells (GI₅₀ < 50 nM), but is far less potent against normal peripheral blood mononuclear cells (PBMCs) (GI₅₀ > 10 μM), supporting a favorable safety profile^[1].
Tambiciclib dimaleate (0.03-3 μM, 2 h) potently and dose-dependently inhibits the phosphorylation of RNA Pol II at Ser2 (EC₅₀ < 300 nM) in OCI-AML-3, MV4-11, and HL-60 cells, while showing no effect on the CDK7-mediated phosphorylation of RNA Pol II at Ser5 or CDK9 at Thr186, confirming its high selectivity over CDK7^[1].
Tambiciclib dimaleate (0.03-0.1 μM, 10 h) downregulates MCL1 and MYC expression at the transcriptional level alongside a broader reduction in overall transcription in MV4-11 cells^[1].
Tambiciclib dimaleate (0.01-0.1 μM, 24 h) induces apoptosis in OCI-AML-3, MV4-11, and HL-60 cell lines, as evidenced by the cleavage of caspase-3 and PARP^[1].
Tambiciclib dimaleate (0.01-0.05 μM, 24 h) has no effect on the cell cycle distribution of MV4-11 and OCI-AML-3 cells, consistent with the lack of significant changes in the expression of key cell cycle regulators (E2F1, Cyclin D1, CDC2) in MV4-11 cells^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
