一般描述
Norepinephrine is a neurotransmitter found in both the peripheral and central nervous systems. It triggers effects associated with the ′fight or flight′ response and is mediated by the family of adrenergic receptors. Structurally, it is a catecholamine due to the presence of the catechol moiety (consisting of two hydroxyl groups on a benzene ring) and an amine (NH2) group.[1] Norepinephrine exhibits pharmacologic effects on α1 and β1 adrenoceptors. It does not elevate heart rate. The primary advantage of norepinephrine is to improve organ perfusion by increasing vascular tone. Compared to dopamine, norepinephrine is more effective at achieving targeted endpoints, less metabolically active than epinephrine, and reduces serum lactate levels. Moreover, it notably enhances renal perfusion and splanchnic blood flow in sepsis, especially when used alongside dobutamine.[2] Norepinephrine is used in the treatment of hypotension, depression, schizophrenia, and attention deficit/hyperactivity disorders.应用
(−)-Norepinephrine has been used: as anαand β-AR agonist to stimulate mouse organoids to study the pathways that are activated upon intestinal epithelial adrenergic receptor (AR) stimulation[3],to measure the monoamine levels in various limbic regions of mouse brains by high-performance liquid chromatography (HPLC) coupled with an electrochemical equipped with an auto-sampler[4],
as a dispersal agent in biofilm dispersion assay to study its effects on the dispersal of Mannheimia haemolytica biofilms[5]

文献和实验原文也可写做 norepinephrine或 L- arterenol。它是从副肾髓质和肾上腺素一起被提取出来的激素(广义)。在哺乳动物中,它从交感神经的末端作为化学传递物质被分泌出来。是从肾上腺素中去掉 N-甲基的物质。牛的副肾髓质里去甲肾上腺素和肾上腺素的含量是 1∶ 4( 1份去甲肾上腺素, 4份肾上腺素)。市售的肾上腺素含有 10— 20%的去甲肾上腺素。其作用如表所示与肾上腺素类似,但在量上和或质上均稍有差别。去甲肾

肾上腺素能神经末梢释放的递质。(绝大多数交感节后纤维属肾上腺素能纤维),有少量是由肾上腺髓质分泌(占肾上腺髓质总分泌量的 10~ 20%),为儿茶酚胺化合物。 NAD主要作用于肾上腺素α受体,对心脏的β 1受体有较弱的兴奋作用,对β 2受体无影响。其生理作用与肾上腺素基本相同,但各有特点。对心脏的兴奋作用较弱,主要是缩血管。皮肤粘膜血管收缩最明显,其次是肾血管,此外脑、肝、肠系膜及骨骼肌等全身血管都呈收缩反应,而冠状血管舒张,这是因为心肌兴奋,心肌代谢产物增多,某些代谢
