Q901
Q901 (CDK7-IN-21) is a selective and potent CDK7 inhibitor with an IC50 of 10 nM. Q901 disrupts MYC and E2FTOP1-DPCs and sensitizes tumor to TOP1 inhibitors by suppressing RNAPII transition from initiation to elongation. Q901 can inhibit tumor growth and significantly enhances tumor growth inhibition combined with TOP1 inhibitors. Q901 can be used for the research of cancer, such as colon cancer and lung cancer.

CDK7 10 nM (IC50) |
Q901 (72-120 h) inhibits the proliferation of MCF-7 breast cancer cells with IC50 values of 95 nM (72 h), 16 nM (96 h) and 5 nM (120 h)[1].
Q901 (100 nM, 1-24 h) traps CDK7 at promoter-proximal regions, reduces chromatin-bound RNAPII and its Ser5/Ser2 phosphorylation, and downregulates MYC/E2F-driven transcription programs[1].
Q901 (10-1000 nM, 24-72 h) downregulates DNA damage repair (DDR) genes and increases p-H2AX levels, inducing DNA damage accumulation in MCF-7 cells[1].
Q901 (1 μM, 24 h) reduces ubiquitination of TOP1-DPCs induced by TPT (1 μM, 0.5-2 h) and prolongs the stability of TOP1-DPCs in MCF-7 cells[1].
Q901 combined with Topotecan (HY-13768), T-DXd (HY-138298) and Sacituzumab govitecan (HY-132254) synergistically inhibits the proliferation of H82, DMS53 small cell lung cancer cells, HCT116 colon cancer cells and H292 lung cancer cells[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- 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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL (4.10 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 2.5 mg/mL.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (4.10 mM); Clear solution; Need ultrasonic
