CDK9/cyclinT1 (IC50 = 1 nM); CDK16/Cyclin Y (IC50 = 292 nM); Cdk1/cyclin B (IC50 = 1.34 μM); CDK14/Cyclin Y (IC50 = 1.68 μM); CDK7/Cyclin H/MNAT1(IC50 = 1.72 μM); cdk2/cyclin A (IC50 = 2.86 μM); Cdk5/p25 (IC50 = 4.64 μM)

| ln Vitro |
JSH-150 demonstrates an IC50 of 1 nM in the biochemical assay against CDK9 kinase and attains selectivity over other members of the CDK kinase family that is approximately 300–10,000 times higher. High selectivity over other 468 kinases/mutants is another feature of it. With regard to melanoma, neuroblastoma, hepatoma, colon cancer, lung cancer, and leukemia cell lines, JSH-150 exhibits strong antiproliferative properties. It can suppress MCL-1 and C-Myc expression, halt the cell cycle, and cause apoptosis in leukemia cells in a dose-dependent manner. It can also inhibit the phosphorylation of RNA Pol II.[1]

| ln Vivo |
JSH-150 at a dosage of 10 mg/kg can virtually completely stop the growth of tumors in the xenograft mouse model inoculated with MV4-11 cells. JSH-150 is a promising drug candidate for leukemia and other cancers, and its good in vivo PK/PD profile and high selectivity make it an excellent pharmacological tool to study CDK9-mediated physiology and pathology.[1]

| Enzyme Assay |
The kinase reaction system comprises 10 μM ATP, 0.5 μL of serially diluted compounds 11–43 (including JSH–150), and 5 μL of CDK9 substrate PDKtide (0.2 μg/μL) with CDK9/CyclinK kinase (3 ng/μL). Each tube's reaction is initiated instantly by adding ATP, and it continues at 37 °C for an hour. 5 μL solvent reactions are conducted in a 384-well plate after the tube has been cooled for five minutes at room temperature. Subsequently, 5 microliters of ADP-Glo reagent are introduced into every well to halt the reaction and utilise the residual ADP in 40 minutes. Lastly, a luminescence signal is generated by adding 10 μL of kinase detection reagent into the well and incubating it for 30 minutes. The dose-response curve is fitted with Prism 7.0, and the luminosity signal is measured using an automated plate reader.

| Cell Assay |
Investigation of Signaling Pathways. For two hours, DMSO, serially diluted JSH-150, and 1 μM compound 7 are applied to MV4-11, HL-60, and MEC-1 cells. Following that, the cells are lysed in cell lysis buffer and rinsed in 1 × PBS. For immunoblotting, the following antibodies are used: phospho-CDK9 (Thr186), CDK9, phospho-RNA Pol II (Ser2), phospho-RNA Pol II (Ser5), RNA Pol II, XIAP, MCL-1, C-MYC, BCL-2, and GAPDH.

| Animal Protocol |
Mice: Female nu/nu mice aged five weeks are utilized. Cells are taken during exponential growth before being implanted. Five million MV4-11 cells in PBS are combined 1:1 with Matrigel and injected into the right flank subcutaneous space of nu/nu mice. When MV4-11 tumors are 200–400 mm3 in size, daily oral administration is started. Then, for efficacy research, the animals are randomly assigned to treatment groups consisting of five mice apiece. Every day, JSH-150 is given orally via gavage in an HKI solution (0.5% methocellulose/0.4% Tween80 in ddH2O). JSH-150 or its vehicle as a control are given in a range of dosages. JSH-150 is administered orally to female nu/nu mice with established MV4-11 tumor xenografts at doses of 10, 20, and 30 mg/kg/d, or as a vehicle. Following JSH-150 treatment, daily measurements of body weight and tumor growth are made. Volume of tumor is computed.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
