Description

technical field [0001] The invention relates to 7,4'-disubstituted isoflavone derivatives and a preparation method and application thereof, belonging to the field of medicinal chemistry. technical background [0002] As a kind of phytoestrogens, isoflavones have a series of physiological activities. It has a certain therapeutic effect on breast cancer, colon cancer, lung cancer, prostate cancer, skin cancer and leukemia, and can also prevent the occurrence of ovarian cancer, colon cancer, gastric cancer and prostate cancer. The antitumor activity data of the compounds involved in the existing structure-activity relationship research shows that the antitumor activity of most synthetic derivatives is not significantly improved compared with isoflavones themselves, so it can be seen that the antitumor activity of isoflavones has not been greatly improved. good development. [0003] The present invention uses tivolone as a control drug, which has obvious inhibitory effect on v...
