Description: Highly potent PSAM4-GlyR and PSAM4-5-HT3 chimeric ion channel agonist; brain-penetrant
Chemical Name: 1-Methyl-7,8,9,10-tetrahydro-1H-6,10-methanoazepino[4,5-g]quinoxalin-2(6H)-one hydrochloride
Purity: ≥98% (HPLC)
Biological Activity for uPSEM 792 hydrochloride
uPSEM 792 hydrochloride is an ultrapotent PSEM (uPSEM) agonist for PSAM4-GlyR and PSAM4-5HT3 (Ki = 0.7 nM for PSAM4-GlyR and <10 nM for PSAM4-5HT3). Exhibits >10,000-fold agonist selectivity for PSAM4-GlyR over α7-GlyR, α7-5HT3, and 5HT3-R, and 230-fold selectivity over α4β2 nAChR. Also weak partial agonist (~10 %) at α4β2 nAChR. Retains the potency of varenicline (Cat.No. 3754) for PSAM4-GlyR with enhanced chemogenetic selectivity. Does not act as a substrate for P-glycoprotein pumps. Silences neurons in vivo. Brain-penetrant.
