There are disclosed substituted arylthiazolidine carboxylic acid analogs, derivatives and related compounds of the formula:
wherein:
R and R3 are the same or different and are hydrogen, loweralkyl, aralkyl;
R, is alkyl of from one to ten carbon atoms which include, branched, cyclic and unsaturated alkyl groups; substituted alkyl of from one to six carbon atoms wherein the substituent is amino, arylthio, aryloxy, hydroxy, arylamino, and acylamino; or alkyl and heteroaralkyl optionally substituted by halo, loweralkyl, hydroxy, aminoloweralkyl, alkoxy and amino groups and wherein the alkyl group contains from one to six carbon atoms;
R2 is an aryl, substituted aryl, heteroaryl or substituted heteroaryl group selected from the group consisting of phenyl, naphthyl, or biphenyl wherein the substituent is hydroxyl or lower alkyloxy;
X is CH2 or S;
and, the pharmaceutically acceptable salts thereof as well as processes for preparing the same. These compounds are angiotensin converting enzyme inhibitors which are useful for treating hypertension.
