CHPG sodium salt
Based on 4 publication(s) in Google Scholar
CHPG sodium salt is a selective mGluR5 agonist, and attenuates SO2-induced oxidative stress and inflammation through TSG-6/NF-κB pathway in BV2 microglial cells. CHPG sodium salt protects against traumatic brain injury (TBI) in vitro and in vivo by activation of the ERK and Akt signaling pathways..

CHPG sodium salt (10-500 μM; 24 hours) significantly increases the cell viability and decreases the LDH release after SO2 derivatives treatment[1].
CHPG sodium salt (0.5 mM; 30 mins ) protects BV2 cells against SO2-induced apoptosis[1].
CHPG sodium salt (0.5 mM; 30 mins) treatment alone increases the expression of TSG-6 in both mRNA and protein levels[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 (11.18 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
