Problems solved by technology

[0007] The content of Mansonone F in nature is very low, it is difficult to obtain in large quantities, and its antibacterial and anti-tumor activity is not ideal, so we use Mansonone F as the lead compound, modify its structure, and study other possible pharmacological effects to seek anti-tumor The new drug of Mansonone F derivatives with better activity and better anti-drug resistance is of great significance for the treatment of anti-tumor and drug-resistant tumors

Abstract

The invention discloses application of a series of non-6-site methyl substituted o-quinone structure-contained compounds in aspect of preparing anticancer medicaments. The compounds are derivatives obtained by reforming a Mansonone F (mansonone, Msn) structure, and the compounds comprise the structural formula shown in the specification, wherein A expresses the formula shown in the specification. The anticancer cell toxic activity IC50 of the o-quinone structure-contained compounds disclosed by the invention is equal to 1-20mu M(NCI-460 and PC-3 cell strain). The activity of certain compounds is tens of times stronger than that of etoposid and is 50 times stronger than that of a natural product Mansonone F. The invention has favorable application prospect.

Description

field of invention [0001] The invention relates to an antitumor compound, in particular to the application of a derivative of Mansonone (Msn) F containing an o-quinone structure in the preparation of antitumor drugs. Background technique [0002] [0003] Mansonone compounds are compounds with a quinone structure in a class of natural products. They are mainly extracted and isolated from the heartwood of mansonia altissima and ulmus glabra. They are used as phytoalexins. It is a class of substances that plants themselves produce and gradually accumulate to fight against foreign bacterial or fungal infections. It can be used in the treatment of the Dutch elm disease (DED) fungus, a plant disease that once caused the death of large elm trees in Europe and North America. This type of compound has a novel structure, and some compounds have the structure of oxabenzobenzopyran (oxaphenalene), which is relatively rare in natural products. According to research, this type of co...
