Abstract: The angiotensin (Ang) II converting enzyme (ACE II) pathway has recently been shown to be associated with several beneficial effects in various organisms, including gastroprotection. ACE II is responsible for converting Ang II into an active peptide, Ang-(1–7), which in turn binds the Mas receptor. Recent studies have shown that diminazene aceturate (Dize) a trypanocidal used in animals, activates ACE II. Thus, in this study, we aimed to evaluate the gastroprotective effects of Dize via the ACE II/Ang-(1–7)/Mas receptor pathway against gastric lesions induced by ethanol and acetic acid in mice. The results showed that Dize could promote gastric protection via several mechanisms, including increased levels of antioxidants and anti-inflammatory factors (e.g., decreasing tumor necrosis factor and interleukin-6 expression and reducing myeloperoxidase activity), maturation of collagen fibers, and promotion of re-epithelialization and regeneration of gastric tissue in different injury models. Thus, Dize represents a novel potential gastroprotective agent.
