Application

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.
H2 histamine receptor agonist.

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.

Microglia, the principal sentinel immune cells of the central nervous system (CNS), play an extensively vital role in neuroinflammation and perioperative neurocognitive disorders (PND). Histamine, a potent mediator of inflammation, can both promote and prevent microglia-related neuroinflammation by activating different

1. The histamine H2 receptor agonists, dimaprit, impromidine, amthamine, and several dimaprit- and impromidine-analogues were investigated for their spasmolytic activity on the guinea pig duodenum, precontracted with acetylcholine or KCl. 2. Almost all the H2 receptor agonists exerted a histamine

The cardiovascular effects of the new histamine H2 receptor agonist amthamine were studied in the anaesthetized rat, with particular reference to a possible interaction with the adrenergic system. Amthamine (0.03-3 mumol/kg i.v.) caused vasodepressor responses which were antagonized by famotidine
