    Description

    AR-C155858 is a selective monocarboxylate transporter MCT1 and MCT2 inhibitor with Kis of 2.3 nM and 10 nM, respectively.

    IC50 & Target

    MCT1

     

    MCT2

     

    In Vitro

    AR-C155858 (10 nM-100 nM) inhibits MCT1/MCT2 C-terminal chimaeras[1]. AR-C155858 inhibits MCT2, and the 70% inhibition seen at 10 nM is followed by a gradually increasing inhibition which can only be explained by a Ki value of significantly less than 10 nM. AR-C155858 inhibits MCT1 expressed in Xenopus oocytes in a time- and concentration-dependent manner[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: ≥ 2.75 mg/mL (5.96 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 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% (20% SBE-β-CD in Saline)

      Solubility: ≥ 2.75 mg/mL (5.96 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 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.

    Kinase Assay
    [1]

    MCT kinetic assays are performed by monitoring intracellular pH with H+-sensitive dye BCECF or by determining the uptake of l-[14C]lactate (7.4 MBq/mL). The uptake buffer containes 75 mM NaCl, 2 mM KCl, 0.82 mM MgCl2, 1 mM CaCl2 and 20 mM Tris/Hepes (pH 7.4). AR-C155858 inhibitor titrations are performed at pH 6 with oocytes preincubated for 45 min in a different uptake buffer (75 mM NaCl, 2 mM KCl, 0.82 mM MgCl2, 1 mM CaCl2 and 20 mM Mes, pH 6) containing the required concentration of AR-C155858 prior to measuring the uptake of l-[14C]lactate (0.5 mM). Unless stated otherwise, uptake is determined over 2.5 min for all MCT constructs except for MCT2trn with or without embigin and MCT2/1 with or without embigin, where 5 and 10 min are used respectively.

    Cell Assay
    [1]

    The erythrocytes (5% haematocrit) are pre-incubated for 1 h at room temperature (22°C) with or without AR-C155858 at the required concentration before assaying transport of l-lactate (10 mM) at 6°C. Initial rates of transport are calculated by first-order regression analysis of the time course of pH change and converted into nmol of H+/min by determining the pH change induced by small additions of standardized NaOH.

    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.
