Abstract

The invention discloses curcumin-containing aryl metal complexes which can effectively improve bioavailability of curcumin and have good phototoxicity, anti-cancer activity, angiogenesis inhibiting capacity and antibacterial activity. The invention further discloses a synthetic method of the curcumin-containing aryl metal complexes. The method adopts simple technical process, is easy to operate and high in yield. The invention finally discloses an application of the curcumin-containing aryl metal complexes to preparation of anti-cancer drugs, anti-cancer drug components, anti-tumor metastasisdrugs, anti-tumor metastasis drug components, antibacterial agents and antibacterial agent components.

Description

technical field [0001] The present invention relates to a class of curcumin aryl metal complexes, and also relates to the synthesis method of the curcumin aryl metal complexes and their use in the preparation of anticancer drugs, anticancer drug components, anti-tumor metastasis drugs, anti-tumor metastasis Applications in pharmaceutical components, antimicrobials and components of antimicrobials. technical background [0002] The potential medicinal value of natural products has made the anti-tumor research of natural products gradually become a hot spot in clinical anti-tumor drug research. Curcumin is a class of active ingredients extracted from the rhizome of the ginger plant turmeric. Studies have shown that curcumin itself has biological activities such as lowering blood fat, anti-tumor, anti-inflammatory, choleretic, and antioxidant. The antioxidant activity and anti-inflammatory effect of curcumin are related to the occurrence of many diseases in the human body and ...
