The synthesis of spirapril (5), spiraprilat (25), their RSS stereoisomers, and their glycyl (18b) and lysyl (36, 37) analogues is described. These compounds were evaluated in vivo for inhibition of angiotensinconvertingenzyme (ACE), and selected compounds were evaluated for in vitro ACE inhibition (spirapril ID50 16 micrograms/kg; spiraprilat IC50 0.8 nM, ID50 8 micrograms/kg). In anesthetized rats
