背景说明 |
Buspirone Hydrochloride是一种5HT(1A)受体激动剂。 |
生物活性 |
Buspirone, a serotonergic (5HT(1A) receptor agonist) anxiolytic drug with some D(2) dopaminergic effect.[2] Buspirone, a clinically effective non-benzodiazepine anxiolytic drug, caused inhibition of firing of these neurons when given by intravenous (ED50 = 0.011 mg/kg, i.v.), intraperitoneal (ED50 = 0.088 mg/kg, i.p.), and intragastric (effective dose = 1.0-20.0 mg/kg, i.g.) injection.[3] |
In Vitro |
Buspirone also inhibited these cells when it was administered to the outside of recorded neurons by microiontophoresis(effective currents = 2-15 nA).[3] |
In Vivo |
In l-DOPA-primed rats,buspirone dose-dependently reduced LID and improved l-DOPA-related motor performance due to action at the 5-HT(1A)receptor. [1] Buspirone,a serotonergic(5HT(1A)receptor agonist)anxiolytic drug with some D(2)dopaminergic effect,had a pronounced anxiolytic-like effect in the zebrafish diving model at doses that did not have sedative effects.[2] |
动物实验 |
To test this,male Sprague-Dawley rats received unilateral 6-hydroxydopamine(6-OHDA)lesions. In experiment 1,l-DOPA-primed rats were pre-treated with Vehicle(0.9% NaCl),various doses of the partial 5-HT(1A)agonist,buspirone(0.25,1.0 or 2.5 mg/kg,ip)or buspirone(2.5 mg/kg,ip)+the 5-HT(1A)antagonist,WAY100635(0.5 mg/kg,ip)5 min prior to l-DOPA(12 mg/kg+15 mg/kg benserazide,ip). Rats were tested for LID using the abnormal involuntary movements(AIMs)scale and motor performance using the forepaw adjusting steps test(FAS). In experiment 2,l-DOPA-na ve rats received co-administration of l-DOPA+buspirone(1.0 or 2.5 mg/kg,ip)for 2 weeks. [1] |
