The Role of Neprilysin in Peptide Degradation

Neprilysin (NEP) is a transmembrane enzyme with a broad substrate specificity. Its primary function within the cardiovascular system is to break down numerous vasoactive peptides, effectively terminating their biological actions. This includes the degradation of atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and C-type natriuretic peptide (CNP). Neprilysin also cleaves other important vasoactive substances such as bradykinin, substance P, and constituents of the renin-angiotensin system.

The Therapeutic Significance of Neprilysin Inhibition

Given that neprilysin is responsible for breaking down these beneficial natriuretic peptides, inhibiting its activity has emerged as a significant therapeutic strategy. Neprilysin inhibition leads to increased circulating levels of natriuretic peptides, thereby augmenting their protective effects. This approach has become a focus of considerable interest in cardiology, particularly for the management of heart failure (HF).

One of the most notable advancements in this field is the development of angiotensin receptor-neprilysin inhibitors (ARNI), such as the combination of sacubitril/valsartan.作者：NE Ibrahim·2019·被引用次数：153—Neprilysin is an endopeptidase that is responsible for the breakdown of numerous vasoactive peptides (atrial natriuretic peptide [ANP], pro-ANP ...
