Biological Activity

Description

Terbutaline Sulfate(Terbutaline hemisulfate) is a selective β2-adrenergic receptor agonist with IC50 of 53 nM.

Targets

β2-adrenergic receptor ^[1]

53 nM

In vitro
In vitro	Terbutaline is a relatively selective β2-adrenergic bronchodilator that has little or no effect on alpha-adrenergic receptors. The drug has exerts a preferential effect on β2-adrenergic receptors but stimulates beta-adrenergic receptors less selectively than relatively selective beta2-agonists. Terbutaline inhibits antigen-induced histamine release from passively sensitized human lung tissue, which contributes to the clinical effectiveness of the drug during treatment of allergic asthma.^[1] Terbutaline also shows competitive reversible inhibition for all BChE variants. The dissociation constants for UU, FF and AA homozygotes are 0.18, 0.31 and 3.3 mM, respectively. ^[2]

In Vivo
In vivo	Terbutaline appears to have a greater stimulating effect on beta-receptors of the bronchial, vascular, and uterine smooth muscles (β2 receptors) than on the beta-receptors of the heart (β1 receptors). This drug relaxes smooth muscle and inhibits uterine contractions, but may also cause some cardiostimulatory effects and CNS stimulation. ^[3]

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.
