用途: Acetylcholine is a neurotransmitter that can induce the opening of calcium channels. Target: Calcium Channel; nAChR; mAChRAcetylcholine in vertebrates is the major transmitter at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system. It is generally not used as an administered drug because it is broken down very rapidly by cholinesterases, but it is useful in some ophthalmological applications.Acetylcholine chloride, more commonly referred to as just acetylcholine, is a cholinergic neurotransmitter that can induce the opening of calcium channels, as well as act on nicotinic and muscarinic acetylcholine receptors. Acetylcholine plays an important role at many sites in the central nervous system. The compound has been shown to have ophthalmological uses and can be broken down quickly by choliesterases. Studies show that non-neuronal acetylcholine influences many basic cells functions, such as mitosis, cells differentiation, cytoskeletal organization, and cell to cell contact, among other functions [1-3]. 作用: 氯化乙酰胆碱为M、N胆碱受体激动药,选择性低,作用广泛、短暂。小剂量即可明显兴奋M胆碱受体,剂量稍大时,也激动N胆碱受体。M样作用表现为血管扩张、心率减慢、心肌收缩力下降、血压降低,胃肠道、支气管、泌尿道和胆道平滑肌兴奋,瞳孔括约肌和睫状肌收缩,泪腺、汗腺、消化腺和支气管腺体分泌增加等。这些M样作用全部可被阿托品所取消。N样作用包括NM和NN受体兴奋所引起的反应。NN受体兴奋后可见全部植物神经节和肾上腺髓质嗜铬细胞兴奋,前者表现为交感和副交感神经同时兴奋,在效应器上呈现拮抗作用,其最终效应常取决于哪一类神经占优势。后者则可促进肾上腺素释放。NM受体兴奋主要表现为骨骼肌收缩,此作用可被筒毒碱所阻断。 物理化学性质: CAS号:60-31-1 常用中文名:氯化乙酰胆碱; 乙酰氯化胆碱 常用英文名:Acetylcholine chloride 分子式:C7H16ClNO2 分子量:181.660 密度:N/A 沸点:N/A 熔点:146-150 °C(lit.) 闪点:N/A 储存条件:库房通风低温干燥 |
