CHPG is a selective mGluR5 agonist, and attenuates SO2-induced oxidative stress and inflammation through TSG-6/NF-κB pathway in BV2 microglial cells[1]. CHPG protects against traumatic brain injury (TBI) in vitro and in vivo by activation of the ERK and Akt signaling pathways[2].

Description	CHPG is a selective mGluR5 agonist, and attenuates SO2-induced oxidative stress and inflammation through TSG-6/NF-κB pathway in BV2 microglial cells[1]. CHPG protects against traumatic brain injury (TBI) in vitro and in vivo by activation of the ERK and Akt signaling pathways[2].

Target	mGluR5 NF-κB ERK Akt
In Vitro	CHPG (10-500 µM; 24 hours) significantly increases the cell viability and decreases the LDH release after SO2 derivatives treatment[1]. CHPG (0.5 mM; 30 mins ) protects BV2 cells against SO2-induced apoptosis[1]. CHPG (0.5 mM; 30 mins) treatment alone increases the expression of TSG-6 in both mRNA and protein levels[1]. Cell Viability Assay[1] Cell Line: BV2 microglial cells Concentration: 10, 50, 100 and 500 µM Incubation Time: 24 hours Result: Increased the cell viability. Apoptosis Analysis[1] Cell Line: BV2 microglial cells Concentration: 0.5 mM Incubation Time: 30 mins Result: Protected BV2 cells against SO2-induced apoptosis. Western Blot Analysis[1] Cell Line: BV2 microglial cells Concentration: 0.5 mM Incubation Time: 30 mins Result: Increased the expression of TSG-6 in both mRNA and protein levels.
In Vivo	CHPG (injection; 250 nM; for 7 days) reduces significantly cerebral lesion volume[2]. Animal Model: Adult Sprague-Dawley male rats weighing 280-320 g[2] Dosage: 250 nM Administration: Injection; for 7 days Result: Reduced significantly cerebral lesion volume.
