SM19712
Based on 1 Customer Validation
SM19712 is an orally active, selective endothelin converting enzyme (ECE) inhibitor. SM19712 inhibits conversion of big ET-1 to ET-1. SM19712 attenuates colonic angiogenesis, tissue injury, inflammation, without altering colon shortening or myeloperoxidase levels in mice. SM19712 can be used for the research of inflammatory bowel disease (colitis), ischemic acute renal failure, acute myocardial infarction, and myocardial ischemia/reperfusion injury.

ECE-1 |
SM19712 potently inhibits ECE solubilized from rat lung microsomes with an IC50 of 42 nM[3].
SM19712 (10-300 μM) shows high specificity for ECE, with no significant inhibitory activity against NEP, ACE, 13 tested receptors, or 9 tested enzymes at concentrations up to 300 μM[3].
SM19712 (1-100 μM; 6 h) concentration-dependently inhibits endogenous ET-1 production in cultured porcine aortic endothelial cells with an IC50 of 31 μM[3].
SM19712 (100 μM) exhibits high selectivity for endothelin-converting enzyme, with minimal inhibitory effects on neutral endopeptidase, angiotensin converting enzyme, collagenase IV, and other proteinase classes[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
SM19712 (3-30 mg/kg; i.v.; single bolus 5 minutes before occlusion) dose-dependently attenuates ischemia/reperfusion-induced acute renal failure in Sprague-Dawley rats[2].
SM19712 (0.3-30 mg/kg; i.v.; single dose) dose-dependently suppresses Big ET-1-induced pressor responses in rats[3].
SM19712 (10-30 mg/kg; p.o.; single dose) significantly suppresses big ET-1-induced pressor responses in rats by 37.2%[3].
SM19712 (25.9 mg/kg bolus, 1.7 mg/kg/min infusion; i.v.; single bolus followed by continuous infusion; duration of experiment) significantly reduces infarct size, serum ET-1 elevation, and serum CPK activity in a rabbit model of acute myocardial infarction induced by coronary occlusion and reperfusion[3].
