    Tozadenant purchased from MedChemExpress. Usage Cited in: PLoS One. 2016 Nov 11;11(11):e0166415.  [Abstract]

    The endogenous Aβ production of SH-SY5Y cells upon the treatment with 0.1% of DMSO (Vehicle), Istradefylline (Istrad.), Preladenant (Prelad.) or Tozadenant (Tozad.) at 30 nM for 24 h is examined.

    Description

    Tozadenant is an adenosine A2A receptor antagonist, with Ki of 11.5 nM on human A2A and 6 nM on rhesus A2A.

    IC50 & Target

    Ki: 6 nM (Rhesus A2A), 11.5 nM (Human A2A)

    In Vivo

    18F-MNI-444 regional uptake is consistent with A2A receptor distribution in the brain. Selectivity is demonstrated by dose-dependent blocking by tozadenant (1.5, 10.5 mg/kg) and preladenant[1].

    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 (6.15 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 (6.15 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 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.

    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.
