Amthamine dihydrobromide is a histamine H2 receptor agonist. Amthamine dihydrobromide has been used to study the effect of mast cells on T regulatory cell function.
Biochem/physiol Actions
Amthamine dihydrobromide is a H2 histamine receptor agonist. Amthamine dihydrobromide, similar to histamine, inhibits H2 receptor-mediated eosinophil peroxidase (EPO) release with IC50 = 0.4 μM; a weak antagonist at H3 and shows no activity at H1 receptors.

The new histamine H2 receptor agonist amthamine, [2-amino-5-(2-aminoethyl)-4-methylthiazole], was tested for its activity on gastric acid secretion in different in vivo and in vitro experimental models. Amthamine induced a dose-related increase in acid secretion both in conscious cats with a
Recently we developed amthamine [2-amino-5-(2-aminoethyl)-4-methylthiazole]. This cyclic analogue of dimaprit proved to be the most potent and selective histamine H2 receptor agonist of a series of substituted 4- or 5-(2-aminoethyl)thiazoles. Quantum chemical studies on histamine (N pi-H tautomer), dimaprit, and

It is well known that both histamine and dimaprit show moderate histamine H2-receptor agonistic activities on the guinea pig right atrium. Quantum chemical calculations on these two compounds showed similarities in electron distributions and molecular electrostatic potentials (MEP's), which could
The cardiac activity of the novel histamine H2-receptor agonist amthamine was investigated in a variety of isolated heart preparations from guinea pigs and humans and in the isolated rabbit aorta. Amthamine caused an increase in the sinus rate of spontaneously

Histamine is a major peripheral inflammatory mediator and a neurotransmitter in the central nervous system. We have reported that histamine induces microglia activation and releases proinflammatory factors in primary cultured microglia. Whether histamine has similar effects in vivo is unknown.
