Problems solved by technology

However, the "indiscriminate attack" of cisplatin drugs on cells makes it kill tumor cells and also cause serious damage to normal cells, causing great toxic and side effects to cancer patients, such as nephrotoxicity, ear Toxicity and neurotoxicity, etc., make patients suffer a lot
In addition, cisplatin drugs have low activity on certain tumor cells (breast cancer, colon cancer, etc.) and primary and acquired drug resistance, etc., this series of defects seriously limits its application in clinical treatment

Abstract

The invention discloses a high-efficiency and low-toxicity anti-cancer compound synthesized by autocatalysis in cells and living bodies. Orthogonal reaction synthesis; among them, metal complexes are platinum, ruthenium, iridium or osmium metal complexes, organic active molecules refer to small organic molecules with certain biological activities, such as anti-inflammatory, antibacterial, anti-angiogenesis and Anti-cancer and other biologically active small organic molecules. The precursor of the organic active molecule is a chemically modified organic active molecule, and the organic active molecule is rhein, oleanolic acid, ursolic acid, naphthalimide, coumaric acid, nonanthrenecarboxylic acid or indomethacin kind of. The invention also discloses a synthesis method of the above-mentioned anticancer compound. The anticancer compound of the present invention has good antitumor effect no matter it is synthesized by extracellular reaction or intracellular reaction.

Description

technical field [0001] The present invention relates to a class of metal complexes based on organic active molecules, and also relates to the self-catalyzed synthesis method of the above-mentioned metal complexes in cells and living bodies and the application in the preparation of anti-tumor drugs or anti-cancer drug components, belonging to biomedical technology field. [0002] technical background [0003] Metal anti-tumor drugs represented by cisplatin have been widely used in the clinical treatment of various types of cancer, and have shown good therapeutic effects on various cancers such as ovarian cancer, testicular cancer, bladder cancer and colorectal cancer, among which The cure rate for testicular cancer patients is as high as 90%. However, the "indiscriminate attack" of cisplatin drugs on cells makes it kill tumor cells and also cause serious damage to normal cells, causing great toxic and side effects to cancer patients, such as nephrotoxicity, ear Toxicity and ...
