Histamine Receptor Control

1-Methyl-4-imidazoleacetic acid hydrochloride is a stable metabolite of Histamine (HY-B1204) that is produced by the oxidation of the primary metabolite, N-methylhistamine.

Cetirizine N-oxide dihydrochloride is an oxidative degradation product of the histamine H1 receptor antagonist Cetirizine (HY-17042).

2-(5,6,7,8-Tetrahydroimidazo[1,5-a]pyridin-1-yl) ethanamine dihydrochloride is a histamine receptor-inactive compound that serves as a negative control.

Meclizine N-oxide is a metabolite of the histamine H1 receptor antagonist Meclizine (HY-B0349A).

Desmethyl mirtazapine (Normirtazapine) hydrochloride is a metabolite of Mirtazapine (HY-B0352). Mirtazapine is a potent and orally active noradrenergic and specific serotonergic antidepressant (NaSSA) agent.

Sopromidine is a potent and stereoselective isomer of the achiral H2-agonist Impromidine (HY-116777).

Cetirizine N-oxide is an oxidative degradation product of the histamine H1 receptor antagonist Cetirizine (HY-17042).
