    Description

    Tonabersat (SB-220453) is a gap-junction modulator. Tonabersat prevents inflammatory damage in the central nervous system[1][2][3].

    IC50 & Target

    Gap-junction[1]

    In Vitro

    Tonabersat, a novel benzopyran derivative, inhibits cortical spreading depression (CSD) and therefore might be able to inhibit the early migraine mechanisms[1].

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

    In Vivo

    Tonabersat (10 mg/kg) significantly inhibits progression of metastatic lesions. Addition of NSC 241240 to either agent profoundly inhibits brain metastasis[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 (6.38 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% (20% SBE-β-CD in Saline)

      Solubility: 2.5 mg/mL (6.38 mM); Suspended solution; Need ultrasonic

      This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

    Method for preparing stock solution: mg drug dissolved in μL  DMSO (Stock solution concentration: mg/mL).
    The concentration of the stock solution you require exceeds the measured solubility. The following solution is for reference only. If necessary, please contact MedChemExpress (MCE).
    Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.
     If the continuous dosing period exceeds half a month, please choose this protocol carefully.
    Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.

    Mice[2]
    Athymic NCR nu/nu mice, Cr:NIH bg-nu-xid mice, B6129SF1/J, C57BL/6J-Tmem173gt/J 'golden ticket', and C57/Bl/6J mice are used at 5-6 weeks of age. For inducible knockdown experiments, mice are given WC2031 in the drinking water (2 mg/mL) and the diet 14 days after injection of cancer cells. For drug treatment experiments, mice are intraperitoneally injected with NSC 241240 (5 mg/kg per 5 days), Tonabersat (MedChem Express) (10 mg/kg per day), or meclofenamic acid sodium salt (20 mg/kg per day). Vehicle (10% DMSO in polyethylene glycol 400) is used in control mice. Quantification of tumour burden is by Bio-luminescent imaging (BLI), performed using an IVIS Spectrum Xenogen instrument and analysed using Living Image software v.2.50.

    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.
