生物活性:
Ipratropium bromide (Sch 1000) hydrate is a muscarinic receptor antagonist, with IC50s of 2.9 nM, 2 nM, and 1.7 nM for M1, M2, and M3 receptors, respectively. Ipratropium bromide hydrate relaxes smooth muscle, can be used in the research for COPD (chronic obstructive pulmonary disease) and asthma.
体内研究:
Ipratropium bromide hydrate (1.0 μg/kg; i.v.; single dose) enhances vagal nerve stimulation induing bronchoconstriction.Ipratropium bromide hydrate (0.04 mg/20 mL and 0.20 mg/20 mL; inhalation for 30 min, rate=30 mL/30 min) can protect the lungs against the cadmium-induced acute neutrophilic inflammation by reducing the parenchyma inflammatory infiltration of neutrophils.Animal Model:Guinea-pigs of the Dunkin Hartley strain
Dosage:0.1-1 μg/kg
Administration:Intravenous injection; single dose
Result:Resulted little blocking effect on post-junctional muscarinic receptors at 0.3 μg/kg, and inhibited ACh-induced bronchoconstriction at 0.5 μg/kg.
Animal Model:Male Sprague-Dawley rats (300-350 g)
Dosage:0.04 mg/20 mL and 0.20 mg/20 mL
Administration:Inhalation; atomization rate of 30 mL/30 min; 30 min
Result:Had no significant effects on any parameters recorded in healthy rats but exerted a protective effect against the inflammatory reaction elicited by cadmium.

Ipratropium bromide hydrate (1 nM, 10 nM, 100 nM; 15 min) exerts its toxic effects via disruption of mitochondrial membrane potential.Ipratropium bromide hydrate (1 nM-1 μM; 4 h) increases infarct size in isolated perfused heart ischaemia/reperfusion experiments with a dose-responsive manner (EC50=22.7 nM).Ipratropium bromide hydrate (0.001 nM-0.1 mM; 2 h) inhibits adult rat cardiac myocyte growth after 4 h hypoxia treatment.
