Angiotensin II has been implicated in cardiac, renal and vascular diseases. <ref>PMID:17083068</ref> 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 <scene name='Lisinopril/Ace/1'>Angiotensin-Converting Enzyme</scene>, utilizing residues like <scene name='Lisinopril/Lisinopril_bound/1'>His 353, Ala 354 (backbone oxygen), Glue 384, Lys 511, His 513, Tyr 520, Tyr 523 and Glu 162</scene> as well as van der Waals interactions between the phenylpropyl group and Val 518. <ref>PMID:15236580</ref> Binding by Lisinopril actively inhibits ACE-1 binding and conversion of angiotensin 1 into angiotensin II.
