Abstract

The invention discloses the use of alkaloids for preparing antitumor drugs. There are two kinds of alkaloids, and the structural formula of the alkaloids that can be used for preparing antitumor drugs is as follows: it has the advantages of remarkable antitumor activity and the like.

Description

technical field [0001] The invention relates to the use of antitumor drugs, in particular to alkaloids with antitumor effects. Background technique [0002] Malignant tumor is a disease that seriously endangers human life. Its mortality rate is second only to cardiovascular and cerebrovascular diseases, and its incidence is increasing year by year. Now there are surgery, radiotherapy and drug therapy methods for tumor treatment, among which drug therapy has positive, positive and irreplaceable effects in tumor treatment or comprehensive treatment, prolonging the life of tumor patients and improving their quality of life. Antineoplastic drugs have been able to cure or control many tumor types, but the overall level has not yet reached a satisfactory stage. Therefore, it is of great significance to research and develop drugs with effective antitumor activity. Obtaining active ingredients from natural plants and using them as lead compounds is one of the important ways to res...
