Application

3-Morpholinosydnonimine hydrochloride has been used:
  • as a peroxynitrite donor standard to study the accumulation of peroxynitrite in Arabidopsis thaliana
  • to study its effects on nitrosative stress in human brain vascular pericytes and human embryonic kidney cells
  • as a ROS to study its effects on mouse embryonic fibroblasts

Biochem/physiol Actions

3-Morpholinosydnonimine participates in the inhibition of cysteine proteases.
Liberates nitric oxide (NO) spontaneously when in solution, activating guanylyl cyclase and causing an increase in cyclic-GMP. This product is a vasodilator and inhibits platelet aggregation. Using molecular oxygen, it generates both superoxide anion and nitric oxide that spontaneously form peroxynitrite.

Nitric oxide (NO) is synthesized in plants in response to stress, and its role in signaling is well-documented. In contrast, very little is known about the physiological role of its derivate peroxynitrite (ONOO(-)), which forms when NO reacts with O(2)(-)
