The preparation of a series of 1-glutarylindoline-2(S)-carboxylic acid derivatives, 6a-v and 21a-c, is described. The above compounds were tested for inhibition of angiotensin converting enzyme. The structure-activity relationship of the series is also discussed. Compound 6u, the most potent member of the series, had an in vitro IC50 of 4.8 X 10(-9) M. Compound 6v, an ethyl ester of 6u, lowered blood pressure 70 mm in spontaneous hypertensive rats at an oral dose of 30 mg/kg.

1-Carboxy-(alkanoyl or aralkanoyl)-indoline-2-carboxylic acids, e.g., those of the formula ##STR1## R=H, alkyl, alkoxy, halogeno or CF.sub.3 ; R'=H or R-phenyl; m=0 or 1; p,q=0 to 2; and derivatives thereof, are antihypertensive and cardioactive agents.
New carboxyalkylacylamino acids which are derivatives of proline, pipecolic acid and azetidine-2-carboxylic acid and have the general formula ##STR1## are useful as angiotensin converting enzyme inhibitors.
New hydroxycarbamoylalkylacyl derivatives of pipecolic acid which have the general formula ##STR1## are useful as angiotensin converting enzyme inhibitors.
