Application

1400W dihydrochloride has been used:
  • as a strong inhibitor of inducible nitric oxide to analyse its effect on intestinal ischemia/reperfusion (I/R) injury model in rat
  • as inducible nitric oxide synthase (iNOS)-selective inhibitor, to elucidate the mechanism of PM10-induced endothelial dysfunction
  • to study its efficacy on renal ischemia/ reperfusion injury in rats
  • as iNOS inhibitor to investigate its ability to counteract spatial memory deficits after hypobaric hypoxia reoxygenation

Biochem/physiol Actions

1400W dihydrochloride is a potent and selective inhibitor of inducible nitric oxide synthase (iNOS).
