Description

MK-0812 is a potent and selective CCR2 antagonist with low nM affinity for CCR2.

IC50 & Target[1]

CCR2

 

In Vitro

MK-0812 completely blocks all MCP-1 mediated response in a concentration dependent manner, with an IC50 of 3.2 nM. This value is similar to the potency observed for the inhibition of 125I-MCP-1 binding by MK-0812 on isolated monocytes (IC50 4.5 nM). In fact, the antagonist not only completely blocks the shape change response to exogenous MCP-1, but also results in a monocyte forward scatter measurement below unstimulated or basal levels. The addition of MK-0812 to rhesus blood also inhibits MCP-1 induced monocyte shape change. The IC50 for MK-0812 in whole blood assays is 8 nM[1] MK0812 is a potent and selective small molecule CCR2 antagonist[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

MK-0812 is administered by continuous i.v. infusion to maintain a constant level of the drug in blood[1]. Administration of MK0812 at 30 mg/kg, p.o. reduces the frequency of Ly6G-Ly6Chi monocytes in the peripheral blood, while no impact on circulating Ly6G+Ly6C+ neutrophil frequency is observed. In addition, MK0812 treatment causes a dose-dependent reduction in circulating Ly6Chi monocytes and a corresponding elevation in the CCR2 ligand CCL2[2].

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (5.32 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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (5.32 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Kinase Assay
[1]

Human whole blood is collected in EDTA tubes and used within 1 h of blood collection. For antagonist treated samples, blood (200 µL) is pre-incubated with MK-0812 (0.1% final DMSO concentration) for 30 min at room temperature. After which, 20 µL of FITC conjugated anti-CD14 antibody and 4 µL of chemokine or buffer is added to each sample and mixed lightly. An aliquot (100 µL) of the blood mixture is incubated for 10 min at 37°C, immediately placed on ice and lightly fixed with 250 µL of ice cold fixative (49 mL PBS, 1.0 mL 4% para-formaldehyde) for 1 min. Red blood cells are lysed by adding 1.0 mL of ice cold lysis solution (0.15 M NH4Cl2, 10 mM sodium bicarbonate, and 1 mM EDTA), and incubated for 20 min on ice. After complete lysis of red blood cells, 100 µL of 4% para-formaldehyde is added and the samples are analyzed by flow cytometry for forward scatter measurements[1].

Animal Administration
[2]

Mice[2]
Female BALB/c mice are used between 8 and 10 weeks of age. SCH563705 or MK0812 are administered in a 0.4% MC solution by 30 mg/kg oral gavage (p.o.). Two hours later, the frequency of CD11b+Ly6G-Ly6Chi monocytes and CD11b+Ly6G+Ly6C+ neutrophils is determined by flow cytometry.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
