    Description

    RS102895 is a potent CCR2 antagonist, with an IC50 of 360 nM, and shows no effect on CCR1.

    IC50 & Target[1]

    CCR2

    360 nM (IC50)

    CCR1

    17800 nM (IC50)

    Human α1a receptor

    130 nM (IC50)

    In Vitro

    RS102895 is a potent CCR2 antagonist, with an IC50 of 360 nM, and shows no effect on CCR1. RS102895 also inhibits human α1a and α1d receptors, rat brain cortex 5HT1a receptor in cells with IC50s of 130, 320, 470 nM, respectively. RS102895 suppresses wild type and D284N mutant MCP-1 receptor (IC50, 550 nM and 568 nM, respectively), less potently inhibits D284A MCP-1 receptor (IC50, 1892 nM), and has no effects on E291A, E291Q, D284A/E291A or D284N/E291Q (IC50, >100,000 nM)[1]. RS102895 ameliorates the increased extracellular matrix (ECM) protein expression by inhibition of CCR2 at 10 μM, and obviously blocks fibronectin and type IV collagen protein expression in high glucose (HG)-stimulated mesangial cells (MCs) at 1 or 10 μM. RS102895 (10 μM) also abrogates the increased TGF-1 levels in MCs treated with MCP-1[2].

    In Vivo

    RS102895 (3 g/L) causes progressive decrease in pain threshold in rats with bone cancer pain (BCP) at day 3-9 after surgery via intrathecal injection, but the pain threshold increases after 12 days. RS102895 also potently reverses the pattern of NR2B, nNOS, and SIGIRR expression in spinal cord[3].

    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 (6.40 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 (6.40 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.

    Cell Assay
    [2]

    Transfected mesangial cells (MCs) are serum restricted for 24 h, after which the medium is replaced by serum-free DMEM containing normal glucose (NG; 5.6 mM), NG+Mannitol (NG+M; 24.4 mM), or high glucose (HG; 30 mM). In addition, nontransfected MCs are cultured under NG, NG+M, or HG with or without RS102895 or anti-TGF-1 antibody (25 μg/mL). Nontransfected MCs are also exposed to medium containing recombinant human MCP-1 (10 ng/mL) or recombinant human TGF-1 (2 ng/mL). At 24 h after the media change, cells are harvested and the conditioned culture media are collected[2].

    Animal Administration
    [3]

    Rats[3]
    CCR2 antagonist RS102895 is dissolved in DMSO. Rats receive daily intrathecal injection of either RS102895 (3 g/L) 10 μL or 10 % DMSO 10 μL between 9 and 20 days after operation. All rats are randomLy divided into five groups (n = 10 per group): Sham group, Sham + RS102895 group, BCP group, BCP + RS102895 group, and BCP + DMSO group. Rats are sacrificed 20 days after operation and the tissue samples from the L4-L5 spinal cord segments are rapidly removed and immediately frozen in liquid nitrogen and stored at −80°C until use for RT-PCR and Western blot[3].

    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.
