Abstract

The invention discloses a 22-nor-stigmasta thiosemicarbazone compound and a preparing method and application thereof. The structural formula of the 22-nor-stigmasta thiosemicarbazone compound is shown in the description. In vitro cancer cell growth and proliferation activity inhibition tests show that the prepared 22-nor-stigmasta thiosemicarbazone compound has a remarkable inhibition effect on various tumor cell strains such as human nipple thyroid gland cancer cells, human oral cavity epidermoid carcinoma cells and cervical cancer. Meanwhile, the 22-nor-stigmasta thiosemicarbazone compound is free of cytotoxicity on human kidney epithelial cells (HEK293T) and can be used for preparing medicine for treating cancer.

Description

technical field [0001] The invention relates to the technical field of medicine. More specifically, the present invention relates to a 22-nor-stigmasteryl thiosemicarbazone compound and its preparation method and application. Background technique [0002] Cancer is a major disease that endangers human health. Overcoming malignant tumors is a difficult problem in modern medicine, and it is also the biggest challenge for the pharmaceutical industry today. At present, various types of anti-tumor drugs are continuously emerging and used clinically, but the anti-tumor drugs used in clinical practice are highly toxic to human tissues, which greatly limits their scope of use. Therefore, finding anticancer drugs with high efficiency, high selectivity and small side effects is the main direction of anticancer drug development. [0003] Among the antineoplastic drugs, Finasteride is currently clinically used to treat benign prostatic hyperplasia, Estramustine phosphate sodium, abira...
