dCDK9-202
Based on 1 Customer Validation
dCDK9-202 a potent CDK9 PROTAC degrader with an DC50 value of 3.5 nM. dCDK9-202 exhibits broad-spectrum anti-tumor activity and extensively disrupts the oncogenic transcriptome. dCDK9-202 can activate Caspase-3/7, increase the level of cleaved PARP, and directly induce apoptosis of tumor cells. dCDK9-202 effectively inhibits TC-71 tumor growth without any signs of toxicity in mice. dCDK9-202 can be used for the study of EGFR-driven cancers such as sarcoma (Pink: CDK9 ligand (HY-178862); Blue: CRBN ligand (HY-W248665); Black: Linker (HY-N8015)).
(Pink: CDK9 ligand (HY-10008); Blue: Cereblon ligand (HY-W248665); Black: linker (HY-N8015)).

dCDK9-202 (10 nM, 0-24 h) treatment of TC-71 cells within 2 hours can significantly reduce the CDK9 protein level, and complete and nearly continuous degradation was achieved within 8 hours[1].
dCDK9-202 (0.1 nM-1 μM, 24 h) exhibitx nanomolar levels of proliferation inhibitory activity in 12 cancer cell lines derived from various tissues such as lung, liver, bone, and brain. For instance, in TC-71 cells, the IC₅₀ is 8.5 nM[1].
dCDK9-202 (10-50 nM, 24 h) activates Caspase-3/7, increases the level of cleaved PARP, and directly induces apoptosis of TC-71 cells[1].
dCDK9-202 (0.25-25 nM, 6 h) significantly reduces the phosphorylation of Ser2 in the CTD domain of RNA polymerase II (p-Rpb1 Ser2) and downregulates a variety of short half-life proteins that are regulated by CDK9 and are closely related to cancer occurrence in TC-71 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 (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
