Description

technical field [0001] The invention belongs to the field of biomedicine and relates to a substituted phenyl compound and its application. Background technique [0002] PD-1 / PD-L1 signaling pathway is one of the hottest topics in the field of cancer treatment and research. New immunotherapy drugs approved for marketing in the past two years, such as Merck's Keytruda and Bristol-Myers Squibb's Opdivo, both target this signaling pathway, using monoclonal antibodies to bind to PD-1 receptors to block signal transmission, thereby activating the body's own immune system The system attacks the tumor. The two new drugs are already approved to treat cancers such as melanoma, and have shown great potential in clinical trials for a number of other cancers. At present, the US FDA has approved 3 macromolecular PD-L1 inhibitors to market, namely Atezolizumab (Tecentriq, the treatment of bladder cancer and non-small cell lung cancer, is the first PD-L1 inhibitor approved by FDA), Avelum...
