P2X7 Receptor |
JNJ-55308942 shows pKis of 8.1and 8.5 for recombinant human and rat P2X7 channels, respectively. In human blood and in mouse blood and microglia, JNJ-55308942 attenuates IL-1β release in a potent and concentration-dependent manner[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In a model of Bacillus Calmette-Guerin (BCG)-induced depression, JNJ-55308942 dosed orally (30 mg/kg), reversed the BCG-induced deficits of sucrose preference and social interaction. After oral dosing, the compound exhibited both dose and concentration-dependent occupancy of rat brain P2X7 with an ED50 of 0.07 mg/kg. The P2X7 antagonist (3 mg/kg, oral) blocked Bz-ATP-induced brain IL-1β release in conscious rats, demonstrating functional effects of target engagement in the brain[2].
JNJ-55308942 (5 mg/kg; p.o.) shows the F, Vss, CL, Cmax and AUC24h values are 81%, 1.7 L/kg, 3.7 mL min/kg, 1747 ng/mL, and 17549 (ng/mL) h, respectively[1].

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: ≥ 4 mg/mL (9.40 mM); Clear solution
This protocol yields a clear solution of ≥ 4 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (40.0 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 4 mg/mL (9.40 mM); Clear solution
