Biological Activity

Description Buspirone(Buspirone hydrochloride) is a serotonergic (5HT(1A) receptor agonist) anxiolytic drug with some D(2) dopaminergic effect, used for anxiety disorders.
Targets
5-HT1A [1]
In vitro
In vitro

Buspirone, a clinically effective non-benzodiazepine anxiolytic drug, causes 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. Buspirone also inhibits these cells when it is administered to the outside of recorded neurons by microiontophoresis. [1] Buspirone is eliminated primarily by oxidative metabolism, which produces several hydroxylated metabolites, including 5-hydroxy-buspirone and 1-pyrimidinylpiperazine. [2]
In Vivo
In vivo

Buspirone (3 mg/rat, i.p.) dose dependently and completely inhibits shock-induced ultrasonic vocalization after systemic injection and after microinjection into the dorsal raphe nucleus of rats, a brain region rich in somatodendritic 5-HT1A receptors. [3] Buspirone (20 mg/kg) decreases immobility in the rat forced swim test. [4] Buspirone is a serotonergic (5HT(1A) receptor agonist) anxiolytic drug with some D(2) dopaminergic effect in a zebrafish model of anxiety. [5] Buspirone dose-dependently reduces LID and improved l-DOPA-related motor performance due to action at the 5-HT(1A) receptor in l-DOPA-primed rats. Buspirone delayes LID development while improving l-DOPA's anti-parkinsonian efficacy indicating the potential long-term benefits of 5-HT(1A) agonists for reduction of l-DOPA-related side effects in l-DOPA-naive rats.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
