Abstract

The invention particularly discloses a 1,1,1-triphenyl-N-(1-(pyridine-2-methylene) methylamine containing complex and belongs to the field of chemical pharmacy. A molecular structural formula of the complex is described in the description. By adopting the complex prepared by a preparation method, the whole complex can be endowed with high anticancer activity, mitochondria targeting and nucleus targeting, has selectivity to cancer cells and has important significance of studying the drug targeting. By taking N'N as an anion ligand of bidentate chelating, the novel complex with high anticancer activity is synthesized and is good in effect and high in activity in cancer prevention and cell imaging. The 1,1,1-triphenyl-N-(1-(pyridine-2-methylene) methylamine containing complex has the advantages of simpleness in technology, low cost, easiness in controlling chemical components, good repeatability, high yield and the like.

Description

technical field [0001] The invention relates to a metal complex, specifically a complex containing 1,1,1-triphenyl-N-(1-(pyridine-2-methylene)methanamine, its preparation method and application, belonging to chemical pharmaceuticals field. Background technique [0002] In 1965, the synthesis of cisplatin revolutionized the treatment of cancer by radiotherapy alone, and many cisplatin derivatives derived from it have also been biologically evaluated. With people's continuous and in-depth research, three platinum anticancer drugs, cisplatin, carboplatin and oxaliplatin, have become metal anticancer drugs approved worldwide, and they are the only metal-based anticancer drugs used in clinical practice worldwide. anticancer drugs. Metal complexes are used in the treatment of about 50% of all tumors, but their use is often accompanied by toxic side effects, such as nephrotoxicity and drug dependence. is glutathione) is inactivated and will flow out of the cell. In order to ove...
