The invention discloses an application of an epoxidase type II inhibitor, the application is the application in preparation of drugs for treating
liver injury,
hepatitis,
hepatic fibrosis, or
liver function decline or complications thereof, and the application discovers that the existing COX-2 selective inhibitors such as
celecoxib and the like and a novel efficient COX-2 selective inhibitor 6, 7, 8, 9, 10, 11, 12, 13, 14, 16, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, the 2, 8-deuterated dimethyl-2-(
trifluoromethyl)-2H-
benzopyran-3-
carboxylic acid disclosed by the invention has the effects of remarkably relieving
liver injury, reducing
necrosis focus and
inflammatory cell infiltration of liver cells and resisting cholestatic
hepatic fibrosis; in addition,
hepatocyte lipid accumulation and ballooning induced by
high fat diet can be reduced, and the progress of lipid
hepatitis is remarkably inhibited; it is found for the first time that the
traditional Chinese medicine composition can significantly reduce the concentration of serum
bilirubin and play a role in relieving hyperbilirubinemia caused by
liver injury or
liver insufficiency; the
traditional Chinese medicine composition can be used for treating neonatal
jaundice, congenital
bile duct atresia, cholestatic
cirrhosis, acute toxic hepatic failure,
bilirubin increase caused by acute
attack of
chronic hepatitis,
chronic hepatic failure or
hepatic encephalopathy and the like; therefore, the method has obvious economic benefit and clinical application value.
