Being used for drug modification, the multi-arm single molecular weight polyethylene glycol and an active derivative thereof provided herein can effectively improve the solubility, stability, and immunogenicity of the drugs, improve the absorption of the drugs in vivo, prolong the half-life of the drugs, and increase bioavailability, enhance efficacy, and reduce toxic and side effects of the drugs. A gel formed from the active derivative of the multi-arm single molecular weight polyethylene glycol provided herein can be used for the preparation of controlled release drugs so as to prolong the action time of the drugs, thereby reducing the number of administrations and improving patient compliance.

The present invention relates to a biaryl derivative expressed by the chemical formula 1, a method for producing the biaryl derivative, a pharmaceutical composition comprising same, and use of same, the biaryl derivative expressed by the chemical formula 1, as a GPR120 agonist, promoting GLP-1 generation in the gastro-intestinal tract, reducing insulin resistance in the liver, muscles and the like from anti-inflammatory activity in the macrophage, pancreatic cells and the like, and allowing effective use in prevention or treatment of inflammation or metabolic diseases such as diabetes, complications from diabetes, obesity, non-alcoholic fatty liver disease, fatty liver disease, and osteoporosis.
