Background

Captopril is a selective and reversible angiotensin-converting enzyme (ACE) inhibitor with an IC50 value of 0.022 μM (1). This small molecule selectively lowers angiotensin II, a hormone that when upregulated has been linked to increased hypertension, atherosclerosis, myocardial hypertrophy, and obesity (2-5). Captopril has also been shown to regulate inflammatory pathways as a reversible inhibitor of leukotriene A4 (LTA4) hydrolase, reducing leukotriene B4 synthesis (6).
