Opis

Biochem/physiol Actions

NAMH, which is produced in the gastric mucosa by H. pylori, is a potent H2R agonist as well as a H3R agonist.

Production of N-alpha-methyl-histamine (NAMH), a histamine H(3) receptor (H3R) agonist, is promoted in Helicobacter pylori infected human gastric mucosa. NAMH acts directly on histamine H(2) receptors (H2Rs) in animals to stimulate acid secretion and to be a H2R agonist. NAMH dose dependently stimulated cAMP productions in CHO-H2R cells. This production was inhibited by famotidine but not by thioperamide. Control CHO cells were unresponsive to either histamine or NAMH. In addition, the effect of NAMH, in terms of cAMP production in CHO-H2R cells, was more potent than that of histamine-that is, with a lower EC₅₀ concentration and higher maximal cAMP production. Both NAMH and histamine, but not R-alpha-methyl-histamine, effectively inhibited [(3)H] tiotidine binding to CHO-H2R cells. These results confirm that NAMH, which is produced in the gastric mucosa by H pylori, is a potent H2R agonist as well as a H3R agonist.

Nα-Methylhistamine dihydrochloride helps in removing or decreasing the headache in migraine prophylaxis. It is highly effective than histamine in inducing cyclic adenosine 3′,5′-monophosphate (cAMP) synthesis.
