Pyr3 selectively and directly inhibits TRPC3 channels among TRPC family members. Application of Pyr3 inhibits TRPC3-mediated Ca2+ influx in a dose-dependent manner with the IC50 value of 700 nM. Pyr3 becomes apparent at 0.3 μM, and is almost complete at 3 μM. Interestingly, Ca2+ influx is inhibited by Pyr3 in cells co-expressing TRPC3 plus TRPC6 but not in cells coexpressing TRPC1 plus TRPC5. The Ang II-induced NFAT translocation is suppressed by Pyr3, but weakly by Pyr2 in a concentration-dependent manner (IC50 value was 0.05 μM for Pyr3 and 2 μM for Pyr2)[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: ≥ 2.08 mg/mL (4.56 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 (4.56 mM); Clear solution
