MEG (hemisulfate)

MEG (Mercaptoethylguanidine) hemisulfate is a potent and selective inhibitor of the inducible NO synthase (iNOS), with EC50s of 11.5, 110, and 60 μM for iNOS, ecNOS, and bNOS respectively in tissue homogenates. MEG hemisulfate is also a potent scavenger of peroxynitrite and inhibits peroxynitrite-induced oxidative processes. MEG hemisulfate has a protective effect in many experimental models of inflammation, including ischemia/reperfusion injury, periodontitis, hemorrhagic shock, inflammatory bowel disease, and endotoxic and septic shock[1][2][3][4].
