Angiotensin converting enzyme 2 (ACE2) is a zinc carboxypeptidase involved in the renin angiotensin system (RAS). This enzyme inactivates the potent vasopressive peptide angiotensin II (AngII) by removing the C-terminal phenylalanine residue. ACE2 is also found to be upregulated in the heart in human and animal models of cardiovascular disease and specifically in the human fibrotic liver [1]. Given the role of ACE2 in the RAS and its suspected involvement in other organ systems, a stable and specific inhibitor of low toxicity would be useful in further elucidating the precise role that ACE2 plays in the pathology of heart and liver disease and as a possible therapeutic for hypotension associated with chronic liver failure.
