Perindoprilat, the metabolite of Perindopril, also known as Aceon

Drag the structure with the mouse to rotate

Better Known as: Aceon

Mechanism of Action

Angiotensin II has been implicated in cardiac, renal and vascular diseases. 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.[1] Perindopril is rapidly metabolized into its highly active metabolite Perindoprilat by hepatic enzymes. Perindoprilat binds to the active site of , actively inhibiting ACE-1 from binding and converting Angiotensin I into Angiotensin II. ACE-1 using residues Gln 265, Lys 495, Tyr 504, His 497, His 337, Tyr 496, Ala 338, Glu 368, His 367, HIs 371, Glu 395 and Asp 399 to tightly affix the inhibitor to the active site of ACE-1.
