Lisinopril, also known as Prinivil

Drag the structure with the mouse to rotate

Better Known as: Prinivil

Mechanism of Action

Angiotensin II has been implicated in cardiac, renal and vascular diseases. [1] Bradykinin, a small peptide that counterbalance the effects of Angiotensin II by acting as a strong vasodilator upon binding AT2, is degraded by the same ACE-1 enzyme. Since ACE-1 is the primary producer of Angiotensin II and degrader of Bradykinins, inhibition of ACE-1 has proven an effective treatment for Hypertension and Congestive Heart Failure. Lisinopril binds to the active site of , utilizing residues like as well as van der Waals interactions between the phenylpropyl group and Val 518. [2] Binding by Lisinopril actively inhibits ACE-1 binding and conversion of angiotensin 1 into angiotensin II.
