Application

1-Methylhistamine dihydrochloride has been used as a standard in the evaluation of histamine levels in aqueous humor of glaucoma patients by liquid chromatography. It has also been used as a substrate to determine amine oxidase activity.

Actions biochimiques/physiologiques

1-Methylhistamine is present in the brain and is a metabolite of histamine that is metabolized by histamine N-methyltransferase. It acts as a biomarker for histaminergic system activity in the cerebrospinal fluid of patients suffering from Alzheimer′s disease (AD), hypersomnia, and other neurological conditions.
Major metabolite of histamine by histamine N-methyltransferase.

Histamine is most densely distributed in the hypothalamus and has an important effect on consciousness or wakefulness. It has been little considered whether general anesthetics could exert their effects on hypothalamic histamine metabolism. The present study was conducted to investigate

Glucagon-like peptide-1 (GLP-1), corticotropin-releasing hormone (CRH), and hypothalamic neuronal histamine suppress food intake, a target of leptin action in the brain. This study examined the interactions of GLP-1, CRH, and histamine downstream from the leptin-signaling pathway in regulating feeding behavior.

Neuropathological studies have reported a strong neurofibrillary degeneration of the tuberomamillary nucleus, the region of origin of histamine neurons, in Alzheimer's disease (AD). Histaminergic neurons enhance cognition and memory, suggesting that their degeneration may contribute to the cognitive decline of

We previously suggested that therapeutic effects of betahistine in vestibular disorders result from its antagonist properties at histamine H(3) receptors (H(3)Rs). However, H(3)Rs exhibit constitutive activity, and most H(3)R antagonists act as inverse agonists. Here, we have investigated the effects
