Pyr10
Based on 3 publication(s) in Google Scholar
Pyr10 is a pyrazole derivative and a selective TRP cation 3 (TRPC3) inhibitor. Pyr10 inhibits Ca2+ influx in carbachol-stimulated TRPC3-transfected HEK293 cells with an IC50 of 0.72 μM (IC50 of 13.08 μM for store operated Ca2+ entry in BRL-2H3 cells). Pyr10 has the ability to distinguish between receptor-operated TRPC3 and native stromal interaction molecule 1 (STIM1)/Orai1 channels.

Pyr10 has the ability to discriminate between the classical Orai-mediated, highly Ca2+ selective signalling pathway and the phospholipase C-dependent Ca2+ entry-mediated by TRPC channels, specifically by TRPC3. Pyr10 (3 μM) completely eliminates TRPC3 currents as well as Ca2+ entry while exerting modest effects on Orai-mediated responses. The selective block of TRPC3 channels by Pyr10 barely affected mast cell activation[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: ≥ 2.5 mg/mL (5.56 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.
Please enter the basic information of animal experiments:

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
