Description

technical field [0001] The invention belongs to the field of medicines, and in particular relates to an alkoxyalkyl-substituted heterocyclic group inhibitor, a preparation method and application thereof. Background technique [0002] Lung cancer is one of the important causes of human cancer death. According to cell type, lung cancer can be divided into small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC), among which NSCLC accounts for 85% of all lung cancer patients. According to statistics, the global NSCLC market in 2016 was about 20.9 billion US dollars, of which the US market accounted for half, followed by Japan, Germany and China. Judging from the existing trends, the non-small cell lung cancer market has maintained continuous growth, and the global market is expected to reach US$54 billion in 2023 (Nature, 2018; 553(7689):446-454). [0003] At present, the main treatment drugs for NSCLC are divided into chemotherapy drugs, molecular targeted drugs ...
