Biological Activity
Treatment of HT29 cells with CCT020312 for 24 hours reveals a concentration-dependent loss of P-S608-pRB signal, with a linear response between 1.8 and 6.1 μM[1].
CCT020312 treatment effectively inhibits cell proliferation (as measured at 96 hours) even if treatment is for 2 hours only with subsequent compound washout, indicating that CCT020312 is capable of eliciting durable rather than transient cytostasis[1].
Treatment of HT29 cells with 10 μM CCT020312 for 24 hours reduces the amount of the G1/S cyclins D1, D2, E and A as well as the CDK catalytic subunit CDK2 and increased the level of the CDK inhibitor p27KIP1 present in such cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
P301S transgenic mice treated with CCT020312 (2 mg/kg; i.p.; once daily for 6 weeks) performes significantly better in Morris water maze[2].

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: ≥ 2.08 mg/mL (3.20 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
