C-021
Based on 2 publication(s) in Google Scholar
C-021 is a potent CC chemokine receptor-4 (CCR4) antagonist. C-021 potently inhibits functional chemotaxis in human and mouse with IC50s of 140 nM and 39 nM, respectively. C-021 effectively prevents human CCL22-derived [35S]GTPγS from binding to the receptor with an IC50 of 18 nM.

The in vitro oxidative metabolic stability of C-021 (Compound 1b) is evaluated by measuring the rate of drug consumption in human liver microsomes (HML), thus providing intrinsic clearance values (CLint). C-021 exhibits CLint value of 17,377 mL/h/kg[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
? C-021 (1 mg/kg; i.p.; daily; for 3 days) significantly less microgliosis in acute liver failuremice[2].

Solvent & Solubility
Ethanol : 50 mg/mL (106.92 mM; ultrasonic and warming and heat to 60°C)
DMSO : 50 mg/mL (106.92 mM; ultrasonic and warming and heat to 80°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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: ≥ 0.71 mg/mL (1.52 mM); Clear solution
This protocol yields a clear solution of ≥ 0.71 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (7.1 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: ≥ 0.71 mg/mL (1.52 mM); Clear solution
This protocol yields a clear solution of ≥ 0.71 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (7.1 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
