Problems solved by technology

Although a series of advances have been made in the field of comprehensive treatment of malignant glioma in the past 10 years, the 2-year survival rate of patients is still less than 30%.
[0018] 2. At present, there is still a lack of drugs that can specifically kill glioma stem cells
[0020] Salinomycin (salinomycin) is a monocarboxylic acid polyether animal-specific antibiotic (the structure is as follows). It is currently used as an anti-coccidial agent for chickens and a growth promoter for piglets and fattening pigs. There is no precedent for its application in the treatment of glioma Or reports that can prove its effectiveness and feasibility

Abstract

The invention provides the application of salinomycin and derivatives thereof in preparing drugs for preventing or treating brain glioma, relates to the new pharmaceutical use of known salinomycin and derivatives thereof and develops a new application area. The salinomycin and derivatives thereof show strong pharmacological actions, have a strong effect of selectively killing brain glioma stem cells, and have good pharmaceutical prospects.

Description

technical field [0001] The present invention relates to the application of salinomycin and its derivatives in the preparation of drugs for preventing or treating brain tumors, more specifically, the application of drugs for preventing or treating brain gliomas. Background technique [0002] Malignant tumors are major diseases that endanger human health, and the global cancer situation will become increasingly serious. In the next 20 years, the number of new patients will increase from the current 10 million per year to 15 million, and the number of deaths from cancer will also increase from 6 million to 10 million per year. According to the statistics of the Ministry of Health, the incidence of malignant tumors in my country is 130.3-305.4 / 100,000 for men and 39.5-248.7 / 100,000 for women. In recent years, there are 1.6 to 1.7 million new cancer patients in my country every year, and the total number is estimated to be about 4.5 million. The mortality rate of malignant tumo...
