Gastric Lipase Inhibitors

Gastric lipase inhibitors represent a diverse class of compounds that directly or indirectly modulate the activity of gastric lipase, an enzyme crucial for lipid digestion. Orlistat and Cetilistat, both pancreatic lipase inhibitors, directly bind to the active site of gastric lipase, stopping the hydrolysis of dietary fats and reducing fat absorption. Olestra, a non-absorbable fat substitute, forms a complex with dietary fats, inhibiting their hydrolysis by gastric lipase. Simvastatin, an HMG-CoA reductase inhibitor, and Taranabant, a cannabinoid receptor antagonist, showcase the indirect modulation of gastric lipase activity by impacting lipid metabolism and composition.Sorbitan monostearate, Polidocanol, and Nafamostat mesylate indirectly influence gastric lipase by altering the emulsification properties of lipids, impacting lipid-containing micelles, and inhibiting serine proteases, respectively. Acarbose, an alpha-glucosidase inhibitor, indirectly modulates gastric lipase by interfering with carbohydrate breakdown, potentially altering lipid availability. Tetrahydrolipstatin (THL), structurally related to Orlistat, directly binds to gastric lipase, inhibiting its activity. The intricate network of gastric lipase inhibitors provides valuable insights into the regulation of lipid digestion and absorption, offering potential strategies for managing weight and addressing obesity-related concerns.
