PSEM 89S TFA

产品介绍 PSEM 89S TFA 是一种产生的离子通道的可透过血脑屏障的选择性激动剂。PSEM 89S TFA 分别对 Q79G 和 L141F 具有正交选择性。
生物活性

PSEM 89S TFA is a selective and brain penetrant agonists for the resulting ion channels. PSEM 89S TFA is orthogonally selective for Q79G and L141F, respectively.

体外研究

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.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究

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.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

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.
