PSEM 308 hydrochloride
PSAM (pharmacologically selective actuator module) agonist. Activates PSAML141F-GlyR chimeric ion channels. Inhibits activity of neurons expressing PSAML141F-GlyR in vivo and activates locus coeruleus noradrenergic neurons expressing PSAML141F,Y115F-5-HT3 ion channels.
Recommended concentration for use in mice is 5 mg/kg or lower.
Plasmid vectors for the transfection of cells with PSAML141F-GlyR and PSAML141F,Y115F-5-HT3 are available from Addgene.
