Description

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.

Biochem/physiol Actions

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.
