3-Morpholinosydnonimine hydrochloride

As the active metabolite of molsidomine, SIN-1 (chloride) is a potent vasorelaxant and inhibitor of platelet aggregation. It produces both NO and superoxide and can therefore be used to generate peroxynitrite under physiological conditions.

White Crystalline Solid

SIN-1 is a metabolite of the vasodilator molsidomine and is considered to be a peroxynitrite releasing compound

3-Morpholinosydnonimine hydrochloride is a metabolite of the vasodilator Molsidomine (M488002) and is considered to be a peroxynitrite releasing compound. Molsidomine Impurity A.

3-Morpholinosydnonimine hydrochloride has been used:

• as a peroxynitrite donor standard to study the accumulation of peroxynitriteinArabidopsis 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

Linsidomine (SIN-1) is an active metabolite of the antianginal drug molsidomine. Its mechanism of action upon the corpus cavernosum involves the release of nitric oxide. Injected intracavernosally it can produce penile erections, but its clinical usefulness has not been fully established.

This compound (the active product of the prodrug SIN-10, molsidomine) acts as a vasodilator and inhibitor of platelet aggregation; longer acting than nitroprusside or nitroglycerin. Decreases myocardial necrosis and reperfusion-induced endothelial dysfunction in models of myocardial ischemia-reperfusion.

3-Morpholinosydnonimine participates in the inhibition of cysteine proteases.
