histamine diphosphate

Histamine phosphate is a potent agonist of histamine receptors and a vasodilatory neurotransmitter. It can activate nitric oxide synthase and is commonly used to induce gastric ulcer models.

Histamine dihydrochloride (Ceplene) is the dihydrochloride salt form of histamine, an endogenous metabolic product. Histamine is an organic nitrogen-containing compound with diverse biological activities. It acts as a potent stimulator of gastric acid secretion, a bronchial smooth muscle constrictor, and a vasodilator, as well as a neurotransmitter with central nervous system activity. It is commonly used to induce gastric ulcer models in research.

Histamine (Ergamine) is an amine derived by the enzymatic decarboxylation of histamine. Histamine is a potent stimulant of gastric secretion, a constrictor of bronchial smooth muscle, a vasodilator, and a neurotransmitter of central action.
