PSEM 89S TFA

Research use only, not for human use.

PSEM 89S TFA is a brain-penetrant and selective ion channels agonist, and is orthogonally selective for Q79G and L141F, respectively.

PSEM 89S TFA is a brain-penetrant and selective ion channels agonist, and is orthogonally selective for Q79G and L141F, respectively.

PSEM 89S (10 or 30μM) activates layer 2/3 cortical neurons expressing (Pharmacologically Selective Actuator Module) PSAML141F,Y115F-5HT3 high conductance (HC).PSEM 89S (10 μM) reversibly silenced transfected neurons by reducing cellular input resistance.

PSEM 89S strongly reduces photostimulation-evoked feeding in mice expressing PSAML141F,Y115F- glycine receptor (GlyR) (30 mg/kg) but not in mice expressing only channelrhodopsin-2 (ChR2) (50 mg/kg).PSEM 89S (30 mg/kg) shows good brain penetrance in mice after minimally invasive intraperitoneal administration. Animal Model:Male Agrp-cre mice (3-6 weeks)Dosage:30 mg/kg Administration:I.p. administration Result:Almost completely suppressed fos (a marker of neuron activation) in ChR2-expressing neurons.Animal Model:C57BL/6 mice Dosage:30 mg/kg (Pharmacokinetic Analysis)Administration:I.p. administration Result:Rised rapidly in serum and brain, and was mostly cleared from both compartments in 1 h.
