Abstract:
Novel pyrimidine, pyridine, pyridazine, pyrazine and triazine compounds are provided of the formula (I). The compounds of the invention are useful for treating hypertension, edema, renal failure, congestive heart failure, psoriasis and glaucoma, and in the prevention and treatment of atherosclerosis or to treat gastrointestinal disorders associated with enhanced contractility and/or motility of intestinal smooth muscle or to treat contractile disorders of the uterus.
Abstract:
A compound of formula (I), or a pharmaceutically acceptable salt thereof is disclosed, as well as processes for and intermediates in the preparation thereof, and a method of antagonizing endothelin.
