Ketomethyldipeptides I. A new class of angiotensin converting enzyme inhibitors.
The design rationale for a new series of angiotensin-converting enzyme (ACE) inhibitors which incorporate a ketone substituent into a peptide backbone is described. Molecular regions which were expected to mimic the binding of an N-acyl tripeptide substrate at secondary binding sites S1 and S1' were systematically varied in order to study the specificity of inhibitor binding and optimize inhibition against ACE. The most effective ketomethyldipeptides inhibit ACE in the 10(-9) M range.
