Angiotensin-converting enzyme (ACE) inhibitors now have an accepted place in the treatment of hypertension and congestive heart failure. With the discovery and development of captopril, several other ACE inhibitors have been synthesized and introduced for clinical use. All ACE inhibitors bind to zinc ions located in the active site of the ACE molecule. ACE inhibitors can be classified according to the ligand of the zinc ion of ACE, into 3 different structural types: (1) the first type such as captopril has a sulphhydryl moiety as the ligand; (2) the second type such as enalapril uses a carboxyl moiety as the ligand; (3) the third type such as fosinopril uses neither a sulphhydryl nor carboxyl group, but a phosphinic acid as the zinc binding moiety. ACE inhibitors can also be classified according to the excretion route of their active moiety, into 2 different excretion route types:(1) excreated mainly through the kidney such as captopril, enalaprilat, lisinopril, benazeprilat, imdaprilat, trandraprilat, etc.; (2) excreated both in the bile and urine such as fosinoprilat, temocaprilat, zofenoprilat etc. ACE inhibitors have clinically beneficial effects not only for patients with either hypertension or congestive heart failure, but also can be used to prevent the progression of renal dysfunction induced by hypertension and diabetes mellitus.
