Description

technical field [0001] The invention belongs to the field of drug synthesis, and relates to 6,7-methylenedioxy-1,2,3,4-tetrahydroisoquinoline derivatives and their preparation methods and applications. It specifically relates to a 6,7-methylenedioxy-1,2,3,4-tetrahydroisoquinoline derivative with N-substituted indole at the 1 or 2 position, its preparation method and its application in medicine on the application. Background technique [0002] A tumor is a new organism formed by excessive proliferation or abnormal differentiation of mature or developing normal cells in the body under the action of relevant factors, usually forming a mass, hence the name tumor. Tumors are divided into two categories, benign and malignant. Malignant tumors are often called cancer, which is a common and frequently-occurring disease that seriously threatens human health. Today, cancer has become the second leading cause of death in the world. In 2007, about 7.6 million people died of cancer, ac...
