Phenazopyridine
Based on 2 publication(s) in Google Scholar
Phenazopyridine is a competitive SARM1 inhibitor, with IC50 145 μM. Phenazopyridine is a TRPM8 antagonist. Phenazopyridine has a local anesthetic/analgesic effect. Phenazopyridine is used to relieve painful symptoms of conditions such as cystitis and urethritis. Phenazopyridine can promote neuronal differentiation and can also be used in the study of traumatic brain injury, peripheral neuropathy and neurodegenerative diseases.

In Vitro
Phenazopyridine (10-30 μM; 12 h) increases mRNA expression of RPS23RG1 in both human SHSY5Y and mouse N2a cells[2].
Phenazopyridine (5-50 μM; 2 min) inhibits menthol induced (50 μM) TRPM8 response in a dose-dependent and reversible manner in HEK293 cells with an IC50 of 9.6 μM[4].
Phenazopyridine hydrochloride(3 μM; 6 weeks) can promote neuronal differentiation in human embryonic stem cells[5].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 0.5 mg/mL (2.34 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 0.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 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: 0.5 mg/mL (2.34 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 0.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
