生物活性

製品説明 JSH-150 is a highly selective and potent inhibitor of CDK9 with IC50 of 1 nM.
in vitro

JSH-150 exhibits an IC50 of 1 nM against CDK9 kinase in the biochemical assay and achieves around 300-10000-fold selectivity over other CDK kinase family members. In addition, it also displays high selectivity over other 468 kinases/mutants. JSH-150 displays potent antiproliferative effects against melanoma, neuroblastoma, hepatoma, colon cancer, lung cancer as well as leukemia cell lines. It can dose-dependently inhibit the phosphorylation of RNA Pol II, suppress the expression of MCL-1 and C-Myc, arrest the cell cycle and induce the apoptosis in the leukemia cells.[1]
in vivo

In the MV4-11 cell-inoculated xenograft mouse model, 10 mg/kg dosage of JSH-150 can almost completely suppress the tumor progression. The high selectivity and good in vivo PK/PD profile suggests that JSH-150 will be a good pharmacological tool to study CDK9-mediated physiology and pathology as well as a potential drug candidate for leukemia and other cancers.[1]

キナーゼアッセイ The ADP-Glo kinase assay
The kinase reaction system contains 4.5 μL of CDK9/CyclinK kinase (3 ng/μL), 0.5 μL of serially diluted compounds 11-43 (including JSH-150), and 5 μL of CDK9 substrate PDKtide (0.2 μg/μL) with 10 μM ATP. The reaction in each tube is started immediately by adding ATP and keeps going for an hour under 37 °C. After the tube is cooled for 5 min at room temperature, 5 μL solvent reactions are carried out in a 384-well plate. Then 5 μL of ADP-Glo reagent is added into each well to stop the reaction and consume the remaining ADP within 40 min. At the end, 10 μL of kinase detection reagent is added into the well and incubated for 30 min to produce a luminescence signal. Luminescence signal is measured with an automated plate reader and the dose−response curve is fitted using Prism 7.0.
