ABSTRACT:
The invention concerns novel 1-benzyl-1,2,5,6-tetrahydropyridine-3-carboxylic acid derivatives of the formula: ##STR1## wherein R.sup.1 is hydroxy, amino, (1-4C)alkylamino, di-[(1-4C)alkyl]amino, benzyloxy optionally substituted by halogeno, or (1-6C)alkoxy optionally substituted by (1-4C)alkoxy, morpholino or di-[(1-4C)alkyl]amino; and benzene ring A bears one or two substituents selected from halogeno, (1-4C)alkyl, cyano, carboxamido, trifluoromethyl and hydroxy; and their pharmaceutically acceptable salts; together with pharmaceutical compositions thereof; and analogy processes for their manufacture.
The compounds of formula I are inhibitors of the aggregation of blood platelets and may be of application in the treatment or prophylaxis of thrombosis or occlusive vascular disease. A representative compound of the invention is 1-(2-chlorobenzyl)-1,2,5,6-tetrahydropyridine-3-carboxylic acid.
