Abstract

Novel quinazoline inhibitors of endothelin converting enzyme are described, as well as methods for the preparation and pharmaceutical compositions of the same, which are useful in treating elevated levels of endothelin and in controlling hypertension, myocardial infarction and ischemia, metabolic, endocrinological, and neurological disorders, congestive heart failure, endotoxic and hemorrhagic shock, septic shock, subarachnoid hemorrhage, arrhythmias, asthma, acute and chronic renal failure, cyclosporin-A induced nephrotoxicity, angina, gastric mucosal damage, ischemic bowel disease, cancer, pulmonary hypertension, preeclampsia, atherosclerotic disorders including Raynaud's disease and restenosis, cerebral ischemia and vasospasm, and diabetes.
