Biological Activity

Description Medetomidine is a selective α2-adrenoceptor agonist, with Ki of 1.08 nM, exhibts 1620-fold selectivity over α1-adrenoceptor.
α2-adrenoceptor [1]
1.08 nM(Ki)
In vitro

Medetomidine is a selectiveα2-adrenoceptor agonist, with Ki of 1.08 nM, exhibits 1620-fold selectivity over α1-adrenoceptor, has very weak or no binding to other neurotransmitter receptors. [1]

In vivo In anesthetized rats, medetomidine (1-100 μg/kg, i.v.) induces a dose-dependent, relatively short-lived reduction in blood pressure and heart rate. In the pithed rat, medetomidine shows very potent vasopressor (PD50 1.7 μg/kg) and sympatho-inhibitory (ID50 1.6 μg/kg) effects without affecting basal heart rate. [2] Medetomidine induces dose-dependent sedation, which at high doses (>100μg/kg) includes loss of the righting reflex and hypothermia. Medetomidine induces a decreases in the turnover rate of biogenic amines in the brain, dose-dependently inhibits norepinephrine (NE) turnover, inhibits brain dopamine turnover at high doses, decreases serotonin turnover.

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.
