Description

technical field [0001] The present invention belongs to the technical field of medicines, and in particular, relates to parthenolide derivatives, a pharmaceutical composition for treating cancer or adjuvant treatment of tumors, a preparation method thereof, and a preparation method of the pharmaceutical compound and composition for anti-tumor therapy. Application in cancer or adjuvant anticancer drugs. Background technique [0002] Tumors are a great threat to human health. There are about 2 million cancer patients in my country, with 1.6 million new cases every year. This is a large group. Anti-tumor research is a very challenging and significant field in the field of life sciences today. . In the past, the treatment methods focused on the eradication and killing of cancer cells. At present, the commonly used antineoplastic drugs in clinical practice are mainly cytotoxic drugs. These anticancer drugs have disadvantages such as poor selectivity, strong toxic and side effects...
