摘要:
This invention is directed to compounds of formula I ##STR1## wherein R.sup.1 is CN, CH.sub.2 CN, CH.dbd.CHCN, CHO, or CH.dbd.CHCO.sub.2 H;R.sup.2 is aryl lower alkoxy, heteroaryl lower alkoxy, aryl lower alkylthio or heteroaryl lower alkylthio wherein each of the aryl and heteroaryl moieties is optionally substituted;R.sup.3 is halogen;R.sup.4 is optionally substituted aryl or optionally substituted heteroaryl;R.sup.5 is carboxy or an acid isostere;X is oxygen or sulphur; andn is zero or 1; or an N-oxide thereof, prodrug thereof solvate thereof, or pharmaceutically acceptable salt thereof, which compounds have endothelin antagonist activity. The invention is also directed to methods for preparing the compounds of formula I and their pharmaceutical use.
