PHA 568487, α-7 nAchR-specific agonist, prevents NF-κb activation in the cells[2].
PHA 568487 treatment significantly reduces the expression of leukocyte infiltration molecules in MCAO rats and in endothelial cells after in vitro ischemia[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
The role played by a7 receptors on neuroinflammation is supported by the decrease of [18F]DPA-714 binding in ischemic rats treated with the a7 agonist PHA 568487 at day 7 after MCAO[3].
PHA 568487-treated ischemic rats show a significant reduction of the cerebral infarct volumes and an improvement of the neurologic outcome compared with non-treated MCAO rats[3].

-
Animal Model:C57BL/6J male mice (10-12 weeks old) with pMCAO[2]
-
Dosage:0.4 and 0.8 mg/kg
-
Administration:Injected intraperitoneally once on day 1, or twice on days 1 and 2, after pMCAO
-
Result:0.8 mg/kg on days 1 and 2 after pMCAO yielded the best effect on infarct volume and behavior tests.
-
Animal Model:Adult male Sprague-Dawley rats[3]
-
Dosage:1.25 mg/kg
-
Administration:Treated i.p. daily with 0.1 mL
-
Result:Showed a significant decrease of [18F]DPA-714 binding in the ischemic cerebral hemisphere in comparison to non-treated ischemic rats.

Solvent & Solubility
DMSO : 25 mg/mL (86.70 mM; ultrasonic and warming and adjust pH to 8 with HCl and heat to 80°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (7.21 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (7.21 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
