Angiotensin converting enzyme (ACE) inhibition offers a useful means of managing hypertension, because ACE inhibitors (ACEIs) are known to serve as agents with antihypertensive properties in addition generating positive metabolic and cardioprotective outcomes. However, current ACEIs linked adverse consequences, so there is requirement for effective but safer compounds, which might be achieved through chemical synthesis or the isolation naturally obtained bioactive molecules. Protein...
