In vivo batch selection In vivo Batch:
Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	1%DMSO 1 40%PEG300 2 5%TWEEN80 3 54%ddH2O Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.	1.500mg/ml (3.21mM)	Taking the 1 mL working solution as an example, add 10 μL of 150 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 540 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	CCR4 (in the [35S]GTPγS-binding and mouse chemotaxis assay) 39 nM CCR4 (in the [35S]GTPγS-binding and human chemotaxis assay) 0.14 μM
In vivo	C021 is a potent CC chemokine receptor-4 (CCR4) antagonist, which significantly reduces microglia activation and phosphorylation of ERK1/2, also alleviates AOM-induced cytokine upregulation in azoxymethane (AOM)-treated mice.
