Abstract

The invention relates to a substituted bismuth (Ⅲ) pyrrolidinylcarbamate complex, the simplified structure of which is as follows. The substituted bismuth (Ⅲ) pyrrolidinylcarbamate complex has good antitumor activity and is effective against gastric cancer, lung cancer, liver cancer, Colorectal cancer, cervical cancer, ovarian cancer, breast cancer, leukemia, colon cancer and other malignant tumors have significant anti-tumor activity, and their development as new anti-tumor drugs has broad application prospects. .

Description

technical field [0001] The invention relates to the technical field of antitumor drugs, in particular to a substituted bismuth (III) pyrrolidinylcarbamate complex, a preparation method thereof and an application in the preparation of antitumor drugs. Background technique [0002] Malignant tumors (cancer) are a serious threat to human health and life. Every year, patients who die from cancer account for about a quarter of the total death toll, and the incidence rate is increasing year by year. Cancer prevention and treatment has become a major issue for medical and life science workers. one of the research topics. The incidence of cancer in my country is astonishing and has become the second most cancer-incidence country in the world. Statistical data (WHOGLOBOCAN2008) shows that all new cancer cases in China are 2.8 million, which is twice the number of new cancer cases in the United States (1.4 million in the United States); In the same year, the number of cancer deaths in...
