Title:Preparation and use of 3-pyridyl substituted-6,6-difluoro bicyclic himbacine derivatives as par-1 receptor antagonists
Abstract: The present invention relates to bicyclic himbacine derivatives of the formula ##STR00001## or a pharmaceutically acceptable salt thereof wherein: R.sup.1 is halo; --CN; alkyl; cycloalkyl; alkoxy; phenyl, which is optionally substituted one or twice independently by alkyl, halo, or --CN; or a thiophene ring, which is optionally substituted once or twice independently by alkyl. The compounds of the invention are effective inhibitors of the PAR-1 receptor. The inventive compounds may be used for the treatment or prophylaxis of disease states such as ASC, secondary prevention of myocardial infarction or stroke, or PAD.
