Description

technical field [0001] The invention belongs to the technical field of medicine. In particular, the present invention relates to a phenoxy acid compound, a pharmaceutical composition containing the compound, and a medical application of the compound. For example, the compounds of the invention are useful in the prevention and / or treatment of metabolic diseases and complications of such diseases. Background technique [0002] With the development of society and economy, the incidence of metabolic diseases such as diabetes, obesity, fatty liver disease, and metabolic syndrome continues to rise. These diseases are not only related to each other, but also lead to a variety of serious complications and a significant increase in the risk of other major diseases such as cancer, cardiovascular and cerebrovascular diseases, etc., and have become one of the greatest threats to human health. [0003] Despite the long-term research on the pathogenesis and treatment of metabolic diseas...
