1-methylhistamine

2-(1-Methyl-1H-imidazol-4-yl)ethan-1-amine is a histamine metabolite.

1-Methylhistamine dihydrochloride is a major metabolite of histamine by histamine N-methyltransferase in the pathway of histidine metabolism. It has been used as a biomarker of histaminergic system activity in the brains of Alzheimer's disease patients as well as those with hypersomnia and other neurological conditions.

1-Methyl-4-imidazoleacetic acid (MIMA) is a stable metabolite of histamine that is produced by the oxidation of the primary metabolite, N-methylhistamine. Urinary levels of MIMA are commonly measured to evaluate histamine secretion, particularly in the context of systemic mastocytosis.

4-Methylhistamine hydrochloride has been shown to inhibit the activity of copper-dependent enzymes such as tyrosinase and dopamine beta-hydroxylase and has also been shown to modulate the expression of genes involved in cell cycle regulation and apoptosis.

4-Methylhistamine serves as a potent agonist for the histamine 4 receptor (H4R), holding promise for research into immune-related diseases, including cancer and autoimmune disorders [1] [2].

2-(1-(methyl-d3)-1H-imidazol-4-yl)ethan-1-amine 2HCl is a deuterated compound of 2-(1-(methyl)-1H-imidazol-4-yl)ethan-1-amine 2HCl. 2-(1-(methyl)-1H-imidazol-4-yl)ethan-1-amine 2HCl has a CAS number of 6481-48-7. 1-Methylhistamine dihydrochloride is a major metabolite of histamine by histamine N-methyltransferase in the pathway of histidine metabolism. It has been used as a biomarker of histaminergic system activity in the brains of Alzheimer's disease patients as well as those with hypersomnia and other neurological conditions.
