Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a class of compounds with specific chemical structures having antitumor activity, in particular to 4,5-dihydrospiro[benzo[c]azepine-1,1'-cyclohexyl]-3( 2H)-ketone compounds and their preparation methods and uses. Background technique [0002] Cancer is a serious public health problem worldwide. Most cancer patients lose their lives due to high mortality and high recurrence rates. It is characterized by the uncontrolled division and spread of abnormal cells in the body. Therefore, the synthesis of effective new anticancer drugs is one of the most important goals of modern medicinal chemistry. Although the current anti-tumor drugs have certain curative effects, there are also problems such as drug resistance, poor selection, and large toxic and side effects. Therefore, this patent designs a new anti-tumor compound based on the natural plant-Erythrina alkaloid, and combines the s...
