Dimaprit dihydrochloride_product_DataBase

Bioactivity	Dimaprit dihydrochloride is a selective histamine H2 receptor agonist, it also inhibits nNOS with an IC50 of 49 μM. Dimaprit dihydrochloride can stimulate gastric acid secretion[1][2].
Invitro	Dimaprit has less than 0.0001% the activity of histamine on H1-receptors[1].Dimaprit (0.1 nM-100 μM) inhibits nNOS concentration dependently with an IC50 of 49±14 μM[2].
In Vivo	Dimaprit stimulates gastric acid secretion in rats (1.25 μM/kg/min; rapid i.v. injection), cats (2-64 μM/h; i.v.) and dogs (1-100 nM/kg/min; i.v.)[1].Dimaprit (0.01-1 μM/kg; i.v. at intervals of 5 min) causes dose-dependent falls in blood pressure in cats. Dimaprit (1-100 nM; intra-arterial injection) causes vasodilatation in the femoral vascular bed, and it (1 μM/kg; bolus or intravenous injection) has no effect on heart rate[1].
