Overproduction of the potent vasoconstrictor peptide endothelin-1 (ET-1) is implicated in the pathogenesis of coronary artery disease. In endothelium-denuded human coronary arteries the response to big ET-1 was significantly enhanced in atherosclerotic arteries (coronary artery disease, CAD; n=7) with an EC50 value of 96 nM (57- 161 nM, 95% C.I.) compared to 274 nM (205-365 nM) in non-diseased arteries (dilated cardiomyopathy, DCM; n=10) (Mann-Whitney U-test, P<0.05). Higher levels of immunoreactive endothelin (ET) could be detected by radioimmunoassay in bathing medium taken from CAD arteries than from DCM arteries (2.8+/-0.5 nM, n=5 vs 1.1+/-0.2 nM, n=7) (Student's two-tailed t-test, P<0.05). There were no differences in responses of arteries from either group to ET-1 (EC50 10 nM, CAD vs 14 nM, DCM). The enhanced response of atherosclerotic human coronary arteries to big ET-1 appears to be due to up-regulation of endothelin-converting enzyme (ECE) activity rather than to an augmented response of the arteries to ET-1. This non-endothelial ECE may therefore be an important therapeutic target in coronary artery disease.

Atherosclerosis is the primary cause of CAD and cerebrovascular disease. Endothelin (ET)-1 is a vasoconstrictive peptide implicated in Atherosclerosis pathology. Endothelin-converting enzyme (ECE) is a membrane metalloprotease that generates endothelin. Reported inhibitors of ECE-1 and their IC(50) values were retrieved from literature and their structures were docked with the parent protein using the Molegro virtual docker. The obtained MolDock scores of each of the compounds are hereby reported and are subject to graphical analysis in conjunction with their respective IC(50) values to characterize potent inhibitors. A search was then run in the ZINC database for compounds with similar properties. Potent inhibitors with higher Dock scores and better Ranking were isolated and are reported.
