The synthesis of a series of novel, potentangiotensinconvertingenzyme (ACE) inhibitors containing saturated bicyclic amino acids in place of proline is described. Octahydroindole-2-carboxylic acid, octahydroisoindole-1-carboxylic acid, and octahydro-3-oxoisoindole-1-carboxylic acid can replace proline in both sulfhydryl and non-sulfhydryl ACE inhibitors to give compounds equipotent to captopril
1-[3-Mercaptoalkanoyl] pyroglutamic acids and 1-[3-mercaptoalkanoyl]-4-hetero (oxa, thia and aza) pyroglutamic acids were prepared and their inhibitory activities against angiotensin-converting enzyme (ACE) were examined. (2S)-1-[(2S)-3-Mercapto-2-methylpropanoyl] pyroglutamic acid 2 was found to be the most potent orally active inhibitor of ACE of rabbit lung among the derivatives synthesized in the present study and appeared to have great potential for use as an oral antihypertensive agent.
