Abstract:
Nonalcoholic fatty liver disease (NAFLD), including nonalcoholic fatty liver (NAFL) and a more advanced condition with inflammation/fibrosis, nonalcoholic steatohepatitis (NASH), is emerging as one of the most prevalent chronic diseases associated with the worldwide expansion of the obese population; however, there are currently only symptomatic therapy but no cure. Among multiple candidate drugs that have been developed and tried in clinical trials against NAFLD/NASH, peroxisome proliferator-activated receptor (PPAR) dual/pan agonists continue to be the most expected ones. This review summarizes the current condition of several PPAR agonists that were and are in clinical trials against NAFLD/NASH. In addition, we recently expanded structural information about PPARα/δ/γ-ligand interactions by X-ray crystallography and executed comparative functional analyses of PPARα/δ/γ activation by those ligands; based on those knowledge, we propose the reevaluation or repositioning of currently approved PPAR agonists, saroglitazar, bezafibrate, and pemafibrate, for the treatment of NAFLD/NASH.

GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...
Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
