Abstract

The invention discloses an application of dehydrolovastatin to preparation of an anti-inflammatory bowel disease medicament. The prevention and control actions and the action mechanism of the dehydrolovastatin on a mouse inflammatory bowel disease induced by dextran sulfate sodium are disclosed for the first time through tests of building a mouse acute inflammatory bowel disease model, observing the treatment effect of the dehydrolovastatin on the inflammatory bowel disease, and the like. The dehydrolovastatin significantly inhibits the levels of proinflammatory factors TNF-alpha, IL-6 and IL-17 by inhibiting an NF-kappa B signal path, raises the level of an anti-inflammatory factor IL-10, and plays a role in preventing the mouse inflammatory bowel disease induced by 4-percent DSS (Dextran Sulfate Sodium Salt).

Description

technical field [0001] The invention relates to the field of medicines, in particular to the application of dehydrolovastatin in the preparation of anti-inflammatory bowel disease medicines. Background technique [0002] Statins are specific competitive inhibitors of hydroxymethylglutaryl-CoA (3-hydroxy-3-methyl-glutaryl CoA, HMG-CoA) reductase, which can reduce the biosynthesis of cholesterol and have a significant It is the drug of choice in lipid-lowering drugs. And reduce the morbidity and mortality of cardiovascular diseases by improving endothelial function, anti-platelet aggregation, and inhibiting atherosclerosis. Studies in recent years have found that statins still have anti-inflammatory and immunomodulatory effects, and play a certain role in many rheumatism, rheumatoid diseases and autoimmune diseases. [0003] Dehydrolovastatin (dehydrolovastatin, DLVT) is a new member of the statin family obtained in recent years. It is a dehydro derivative of lovastatin and ...
