The role of Zinc L-Carnosine in the prevention and treatment of gastrointestinal mucosal disease in humans: a review.

摘要

? 2022 The AuthorsZinc L-carnosine is a pharmaceutical compound with direct mucosal cytoprotective and anti-inflammatory action through its antioxidative effects, cytokine modulation and membrane-stabilizing properties. Chemically, it is not an anti-secretory, antacid or raft-forming agent; its properties are mainly mediated by its higher affinity for damaged mucosa that permits the release of zinc locally by ligand exchange. Beneficial effects on various types of mucosal damage have been described in vitro and in vivo, in both animals and humans. It has been shown to promote repair of mucosal injury in human studies and has been widely used for the treatment of peptic ulcers, chemoradiotherapy-induced oral mucositis and esophagitis. More recently, the therapeutic applications of Zinc L-carnosine have been extended to the prevention and cure of various types of intestinal damage, including ulcerative colitis, iatrogenic ulcers after operative endoscopy, hemorrhoidal disease and impaired intestinal permeability. This review concentrates mainly on the current and future applications of zinc L-carnosine in gastrointestinal disease, and may be of use to gastroenterologists and endoscopists. It describes the therapeutic principles and benefits of this interesting molecule and discusses the potential future fields of interest for clinical use in humans.
