Abstract

The invention discloses a benzyl cyclohexenone derivative and a preparation method and medical application thereof. The benzyl cyclohexenone derivative is a compound in a general formula I. The compound can be individually prepared into a preparation or can be combined with one or more pharmaceutically acceptable carriers to prepare the preparation for administration. The compound can be combined with other antitumor drugs for application, and can also be combined with radiotherapies for application. These antitumor drugs or radiotherapies and the compound disclosed by the invention can be given at the same time or different times. These combination therapies can generate a synergistic effect to improve the treatment effect.

Description

technical field [0001] The present invention relates to the field of medicine, in particular to a class of benzylidene cyclohexenone derivatives and pharmaceutically acceptable salts thereof, their preparation methods, pharmaceutical compositions containing these derivatives and their medical applications, especially Application in preparing drugs for malignant tumors and anti-drug-resistant malignant tumors. Background technique [0002] Cancer is the second leading cause of death in humans after cardiovascular disease. Although a variety of anti-tumor drugs are available clinically, due to the complexity of tumor etiology, drug resistance of tumors, and toxic and side effects of anti-tumor drugs, the existing drugs still cannot meet the needs of treatment. Therefore, it is of great significance to find new anti-tumor drugs with high efficacy, strong targeting and less side effects. [0003] [0004] A large number of studies have shown that finding new drugs from natu...
