Abstract

The present invention relates to a liver injury treating pharmaceutical composition, which comprises a compound represented by the following formula and used as an effective pharmaceutical component,and a pharmaceutically acceptable auxiliary additive, wherein the formula is defined in the specification, and R1 is independently selected from H or alkyl. According to the present invention, by inhibiting the lipid peroxidation reaction and scavenging the free radicals, the liver injury treating pharmaceutical composition can produce the anti-liver-injury effect, reduce the TNF-alpha level in serum, and significantly improve the pathological change of liver tissue.

Description

technical field [0001] The invention relates to the field of medicine, in particular, the invention relates to a pharmaceutical composition for treating liver damage. Background technique [0002] The liver is the largest organ in the body and has extremely important functions such as digestion and metabolism, detoxification, and reuse of metabolites. The loss of liver cell metabolic function and damage to the structural integrity of cytoplasmic junction caused by various injury factors will cause the loss of liver functions such as choleretic, blood coagulation, and synthesis, and produce a series of clinical symptoms. At present, there is still no effective treatment for liver injury. Therefore, there is an urgent need in this field to develop new drugs with good curative effect for alleviating or treating symptoms of liver injury and reducing mortality. Contents of the invention [0003] The object of the present invention is to provide a pharmaceutical composition for...
