In Vitro
dCDK9-202 (compound 14) (0.25-25 nM; 2-24 h) potently and selectively degrades CDK9 in TC-71 Ewing sarcoma cells via a proteasome-dependent CRBN-mediated mechanism, with a DC50 of 3.5 nM, and achieves nearly complete degradation within 8 h at a concentration of 10 nM[1].
dCDK9-202 (0.25-25 nM; 6 h) potently degrades CDK9 in U87 glioblastoma cells, SKUT1 uterine leiomyosarcoma cells and RH5 rhabdomyosarcoma cells, with a DC50 value of less than 10 nM[1].
dCDK9-202 (72 h) potently inhibits the growth of various human cancer cell lines derived from different tissues, with IC50 values ranging from 2.4 nM (RH5 rhabdomyosarcoma) to 174.2 nM (SJSA-1 osteosarcoma)[1].
dCDK9-202 (10 nM; 0-24 h) selectively degrades CDK9 in TC-71 Ewing sarcoma cells within 8 h, without inducing acute off-target degradation of IKZF1/3 or other CDK family members[1].
dCDK9-202 (0.25-25 nM; 6-8 h) impairs Pol2 activity and disrupts the oncogenic transcriptome in TC-71 Ewing sarcoma cells, reduces Pol2 phosphorylation levels, inhibits key oncoproteins and anti-apoptotic proteins, and suppresses pro-tumor signaling pathways[1].
dCDK9-202 (10-50 nM; 24 h) inhibits DNA replication and induces apoptosis in TC-71 Ewing sarcoma cells[1].

In Vivo:
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 (3.11 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
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 (3.11 mM); Clear solution
