Abstract
The invention discloses a biflavone-copper complex and a preparation method and application thereof. The preparation method comprises the following steps of using the biflavone of amentotaxus as a ligand, using copper ions as center ions, and reacting, so as to obtain an amentotaxus biflavone-copper complex; featuring the structure of the complex by ultraviolet-visible light absorbing spectrum and high-resolution mass spectrum. At the same time, the anti-tumor and anti-oxidizing activities of the amentotaxus biflavone-copper complex are studied. After proofing by an MTT (3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di- phenytetrazoliumromide) method, the anti-tumor activity of the amentotaxus biflavone-copper complex is better than the anti-tumor activity of the amentotaxus biflavone; after proofing by a pyrogallol self-oxidizing method and an ABTS (2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) method, the anti-oxidizing activity is better than the anti-oxidizing activity of the amentotaxus biflavone self. The biflavone-copper complex has the advantages that after forming, the anti-tumor activity and anti-cancer activity of the amentotaxus biflavone are improved, and the amentotaxus biflavone-copper complex may be used for developing medicines.
Description
technical field [0001] The invention belongs to the fields of organic synthesis and medicine, and specifically relates to a biflavone-copper complex and its preparation method and application. Background technique [0002] Biflavonoids are unique chemical components of gymnosperms, such as Ginkgo biloba and Selaginella, which have biological activities such as anti-oxidation, anti-inflammation, anti-virus, and anti-tumor. Among them, Amentoflavone (Amentoflavone, Ame) is a relatively common type of amentoflavone compounds, and its structural formula is as follows: [0003] [0004] Sun et al. found that amentoflavone increased the expression of anti-cancer genes by activating hPPARγ, thereby achieving the effect of inhibiting breast cancer cells and cervical cancer cells [Lee E., Shin S., Lee J. et al. Cytotoxic activities of amentoflavone against human Breast and cervical cancers are mediated by increasing of pten expression levels due to peroxisome proliferator-activat...
