一般說明
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. 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. Norepinephrine is used in the treatment of hypotension, depression, schizophrenia, and attention deficit/hyperactivity disorders.
應用
(−)-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,
- 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,
- as a dispersal agent in biofilm dispersion assay to study its effects on the dispersal of Mannheimia haemolytica biofilms

Impulsive behavior is a hallmark of several neuropsychiatric disorders (eg, attention-deficit/hyperactivity disorder, ADHD). Although dopamine (DA) and norepinephrine (NE) have a significant role in the modulation of impulsivity their neural loci of action is not well understood. Here, we investigated

Central dopaminergic and noradrenergic systems play essential roles in controlling several forebrain functions. Consequently, perturbations of these neurotransmissions may contribute to the pathophysiology of neuropsychiatric disorders. For many years, there was a focus on the serotonin (5-HT) system because of

Norepinephrine (NE) control of hypothalamic gluco-regulation involves astrocyte-derived energy fuel supply. In male rats, exogenous NE regulates astrocyte glycogen metabolic enzyme expression in vivo through 5'-AMP-activated protein kinase (AMPK)-dependent mechanisms.
