Therapeutic potential of plant polyphenols in acute pancreatitis

Acute pancreatitis is a potentially life-threatening inflammatory disorder of the exocrine pancreas characterized by early activation of pancreatic enzymes followed by macrophage-driven inflammation, and pancreatic acinar cell death. The most common causes are gallstones and excessive alcohol consumption. Inflammation and oxidative stress play critical roles in its pathogenesis. Despite increasing incidence, currently, no specific drug therapy is available to treat or prevent acute pancreatitis, in particular severe acute pancreatitis. New therapeutic agents are very much needed. Plant polyphenols have attracted extensive attention in the field of acute pancreatitis due to their diverse pharmacological properties. In this review, we discuss the potential of plant polyphenols in inhibiting the occurrence and development of acute pancreatitis via modulation of inflammation, oxidative stress, calcium overload, autophagy, and apoptosis, based on the currently available in vitro, in vivo animal and very few clinical human studies. We also outline the opportunities and challenges in the clinical translation of plant polyphenols for the treatment of the disease. We concluded that plant polyphenols have a potential therapeutic effect in the management and treatment of acute pancreatitis. Knowledge gained from this review will hopefully inspire new research ideas and directions for the development and application of plant polyphenols for treating this disease.
