Angiotensin-converting enzyme converts angiotensin I to angiotensin II, a peptide hormone that impacts vascular smooth muscle tone and renal salt exchange, driving hypertension. Enalapril is an orally-active ACE inhibitor (IC50 values range from 2 to 800 nM). It has roles in the management of hypertension, congestive heart failure, myocardial infarction, and diabetic nephropathies.
