Methacholine chloride
(Synonyms: 醋甲胆碱; Acetyl-β-methylcholine chloride) 目录号 : GC33434
Methacholine chloride是一种有效的毒蕈碱受体激动剂。Methacholine chloride能够直接作用于平滑肌上的乙酰胆碱受体,导致支气管收缩和气道变窄。
Cas No.:62-51-1
Sample solution is provided at 25 µL, 10mM.
Methacholine chloride is a potent muscarinic receptor agonist[1]. Methacholine chloride acts directly on acetylcholine receptors on smooth muscle, resulting in bronchoconstriction and airway narrowing[2, 3]. Methacholine chloride can be used to measure airway hyperresponsiveness (AHR) as a diagnostic aid in evaluating individuals with asthma-like symptoms and normal resting expiratory flow rates[4, 5].
In vivo, Methacholine chloride (0.5mg/kg) induced bronchoconstriction in male Balb c mice by intravenous injection[6].
