Technical Field
The invention relates to a preparation method and application prospect of an amino acid polypyridine copper complex, wherein the complex has good anticancer activity on selected tumor cell strains and has a certain inhibition effect on proteasome activity, so that the complex can be used as a proteasome-targeted antitumor or anticancer drug with potential application value.
Background
Cancer is a general term for a large group of malignant tumors, and is one of the most major diseases that endanger human life at present. At the end of the last 60 years of the century, cisplatin brings about further intensive research on the pharmacological functions of metal complexes by virtue of excellent antitumor effect. Then a plurality of new metal complexes with high efficiency, low toxicity and anticancer performance are continuously synthesized and gradually put into clinical application. Among them, platinum antitumor drugs such as cisplatin and carboplatin have excellent anticancer properties and are becoming the main anticancer drugs. However, because the action target is DNA, the selectivity to tumor cells is lacked, so that the toxic and side effects of gastrointestinal tracts and blood are caused greatly, and in addition, the cisplatin cannot be taken orally and has serious drug resistance, so that the clinical wide application of the cisplatin is limited. Therefore, medical chemists try to develop other metal-based compounds with targets which are not used for platinum or multiple targets so as to improve the selectivity of the compounds on tumor cells, overcome the defects of platinum drugs and expand the clinical anti-tumor spectrum. The ruthenium complex has low toxicity and is easy to be absorbed by tumor tissues, and is regarded as one of the most promising anticancer drugs. In recent years some ruthenium compounds have been successively introduced into clinical trials. Copper is an important essential element required by human body, and is used as a cofactor of some structures and catalytic centers in the organism to participate in a plurality of biological reaction processes in the organism. In recent years, the metal complex, particularly the copper complex, has strong inhibition effect on proteasomes in tumor cells and can induce apoptosis, and has low toxicity on normal cells, thereby providing a basis for developing the metal complex as a targeted medicament.
The polypyridine ligand has strong sigma electron-donating ability and pi electron-accepting ability, has strong anti-tumor activity, can form a stable complex with various metals, can neutralize the positive charge of metal ions, improves the lipophilicity of the complex, can be inserted into DNA or has redox reaction with protein, and the complex is easy to be absorbed by cells, and has great application prospect in the aspects of DNA structure probes, DNA molecular photoswitches, DNA tracing reagents, DNA breaking reagents, anti-cancer drugs and the like; the amino acid is used as a carrier, the water solubility of the compound can be increased, the toxicity is reduced, and the amino acid requirement of cancer attenuated cells is much greater than that of normal cells, so that the anticancer groups can be carried into the cancer cells by introducing the amino acid molecules, thereby improving the effective dose reaching a target and increasing the selectivity of killing the cancer cells.
Based on the research background, the invention introduces an amino acid structure into the polypyridine copper complex, on one hand, the water solubility of the amino acid is utilized, and different molecular frameworks are constructed to regulate the lipid-water distribution coefficient and improve the water solubility of the polypyridine copper complex so as to change the activity of the complex entering cells; on the other hand, the target property of the complex is increased by virtue of the affinity of tumor cells to amino acid. The invention designs and synthesizes amino acid polypyridine copper complex, performs structural representation on the complex, and determines the inhibition effect of the complex on the growth and proliferation of tumor cells and the inhibition effect of the complex on the activity of proteasome so as to obtain the novel metal-based targeted antitumor drug.
