Abstract

The invention discloses a rhein specific group modified organic compound, an aryl metal complex, a preparation method and application thereof. Compared with rhein molecules, the organic compound and metal complex have better antitumor and antibacterial activity, and the metal complex also can induce nucleic acid configuration transformation. Specifically, the aryl metal dimer and the above-mentioned metal complex both have good FTO (fat mass and obesity associated) inhibitory activity, and are good FTO inhibitors. The invention also discloses a synthesis method of the organic compound and themetal complex thereof, and the method has the characteristics of simple technological process, easy operation, and high yield. Finally, the invention discloses application of the rhein group-containing organic compound, the metal complex and aromatic metal dimer thereof in preparation of FTO inhibitor drugs, FTO inhibitor drug components, weight-reducing drugs, weight-reducing drug components, anticancer drugs, anticancer drug components, antibacterial drugs and antibacterial drug components.

Description

technical field [0001] The invention belongs to the field of medicine, and relates to an organic compound modified by a specific group of rhein, a metal complex thereof, a preparation method and an application thereof. technical background [0002] Cancer is one of the most serious diseases threatening human life. According to the data released by the World Health Organization, it is estimated that by 2020, there will be 15 million new cancer patients worldwide every year. Most platinum-based and other drugs currently used clinically have the disadvantages of high toxicity, poor selectivity, and drug resistance. Therefore, research and development of new high-efficiency, low-toxicity anticancer drugs has become an urgent task. With the in-depth study of the mechanism of action of anticancer drugs in tumor cells, many metal anticancer drugs with potential medicines have emerged in recent years. Among them, aryl metal compounds have been found to have good anticancer activity....
