    MDL-28170 (Calpain Inhibitor III) is a potent, selective and membrane-permeable cysteine protease inhibitor of calpain that rapidly penetrates the blood-brain barrier following systemic administration[1][2]. MDL-28170 also block γ-secretase[4].

    IC50 & Target

    Calpain[1].
    In Vitro

    MDL-28170 significantly and time-dependently improves the recovery of synaptic responses in hippocampal slices following prolonged, moderate hypoxia without hypoxic depolarization[1].
    ? MDL-28170 dose-dependently inhibits brain cysteine proteinase activity (in vitro Ki= 0.01 μM)[2].

    In Vivo

    Treatment with MDL-28170 (50 mg/kg, i.p.) completely prevents the striatal damage in four animals in each of the two treatment groups. The numbers of necrotic neurons are reduced by 85% and 68% in animals in which MDL-28170 injections are initiated at 0.5 and 3 h of recirculation, respectively[2].
    ? MDL-28170 (30 mg/kg, i.p.) reduces the functional and structural deterioration of corpus callosum following fluid percussion injury[3].
    ? MDL-28170 (10 mg/kg, i.p.) significantly improves nerve function parameters in diabetic rats. MDL-28170 (3 and 10 mg/kg, i.p.) improves nociceptive behavior in diabetic rats[5].

    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: ≥ 2.25 mg/mL (5.88 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.25 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (22.5 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% Corn Oil

      Solubility: ≥ 2.25 mg/mL (5.88 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.25 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 (22.5 mg/mL) to 900 μL Corn oil, and mix evenly.

    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.
