Method of making a library of compounds using a functionalized polymer

This invention relates to compounds of formula (I), ##STR1## pharmaceutically acceptable salt thereof, and pharmaceutically acceptable solvates of either entity, wherein X is CH or N; Y is optionally monousaturated C.sub.3 -C.sub.5 alkylene optionally substituted with C.sub.1 -C.sub.4 allyl or methylene; R.sup.1 is H; C.sub.1 -C.sub.4 alkyl optionally substituted with C.sub.1 -C.sub.4 alkoxy, OH, NR.sup.5 R.sup.6, CONR.sup.5 R.sup.6, C.sub.3 -C.sub.6 cycloalkyl or aryl; or C.sub.3 -C.sub.6 alkenyl; R.sup.2 is H; C.sub.1 -C.sub.4 alkyl optionally substituted with C.sub.1 -C.sub.4 alkoxy, OH, NR.sup.5 R.sup.6, CONR.sup.5 R.sup.6, C.sub.3 -C.sub.6 cycloalkyl or aryl; or CONR.sup.5 R.sup.6 ; R.sup.3 and R.sup.4 are each independently selected from H; C.sub.1 -C.sub.4 alkyl optionally substituted with NR.sup.5 R.sup.6 ; C.sub.1 -C.sub.4 alkoxy; halo; CONR.sup.5 R.sup.6 and aryl; and R.sup.5 and R.sup.6 are each independently selected from H and C.sub.1 -C.sub.4 alkyl; are potent and selective thrombin inhibitors useful in the treatment of, inter alia, deep vein thrombosis; reocclusion following thrombolytic therapy; chronic arterial obstruction; peripheral vascular disease; acute myocardial infarction; unstable angina; atrial fibrillation; thrombotic stroke; transient ischaemic attacks; restenosis and occlusion following angioplasty; or neurodegenerative disorders.

Antithrombotic amidinophenylalanine and amidinopyridylalanine derivatives

A series of novel octahydro-6-azaindole dipeptide derivatives have been prepared, including their pharmaceutically acceptable salts and bioprecursors therefor. These particular compounds are inhibitors of the angiotensin converting enzyme and are therefore useful in therapy for the treatment of certain cardiovascular disorders, including heart failure and hypertension. Preferred member compounds include 1-[N-(1-S-ethoxycarbonyl-3-phenylpropyl)-S-alanyl]-2-S-carboxy-6-(N-methyl carbamoyl)-octahydro-6-azaindole, 1-[N-(1-S-ethoxycarbonyl-3-phenylpropyl-S-alanyl]-2-S-carboxy-6-methanesul phonyl-octahydro-6-azaindole and 1-[N-(1-carboxy-3-phenylpropyl)-S-lysyl]-2-carboxy-6-methanesulphonyl-octa hydro-6-azaindole, respectively. Methods for preparing these compounds from known starting materials are provided.
