Abstract
Description
technical field
[0001] The present invention relates to a class of dihydropyrrolone derivatives with multiple antitumor activities and their application in the preparation of various tumor suppressor drugs. Background technique
[0002] Cancer is becoming the "second killer" after cardiovascular disease, which seriously endangers human health (CA-Cancer JClin. 2016, 66(1): 7-30), and it is also one of the main diseases causing human death. According to statistics, the incidence and mortality of cancer in my country are generally on the rise, among which lung cancer, breast cancer, and colorectal cancer are at the forefront. At present, the means of clinical cancer treatment include surgical resection, radiation therapy, chemical drug therapy, immunotherapy and gene therapy which have emerged in recent years. Chemotherapy is a method of systemic treatment, and it is the first choice for tumors that have spread and metastasized. However, the existing anticancer drugs are sti...
