Description

A-804598 is a CNS penetrant, competitive and selective P2X7 receptor antagonist with IC50s of 9 nM, 10 nM and 11 nM for mouse, rat and human P2X7 receptors, respectively[1].

IC50 & Target

IC50: 9 nM (mouse P2X7 receptor), 10 nM (rat P2X7 receptor), 11 nM (human P2X7 receptor)[1]

In Vitro

Pre-incubation with A-804598 (0.1-10 μM; 1 hour) significantly attenuates BzATP-induced cell loss in a concentration-dependent manner. 3 μM A-804598 exhibits the greatest protective effect against BzATP-induced cytotoxicity[2].

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

Cell Cytotoxicity Assay[2]

Cell Line: microglial cell
Concentration: 0.1, 0.3, 1, 3, 10 μM
Incubation Time: 1 hour
Result: Protected against BzATP-induced cytotoxicity in both inactivated and activated microglia.
In Vivo

A chroni treatment with A-804598 (intraperitoneal injection; 30 mg/kg; five times a week) decreases the expression of LC3B-II and SQSTM1/p62 in lumbar spinal cord at end stage of disease[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 (7.93 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 (7.93 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 2.5 mg/mL.

    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.
