Abstract

The invention discloses water-soluble o-nitrophenol-containing copper porphyrin and a Schiff base copper porphyrin complex thereof, and a synthesis method and an application thereof, and belongs to the field of chemical application. The synthesis method of THE o-nitrophenol-containing copper porphyrin and the Schiff base complex thereof is disclosed by using functional group modification as a main means. The application of the water-soluble o-nitrophenol-containing copper porphyrin and the Schiff base copper porphyrin complex thereof in biological activity, including the interaction of calf thymus DNA (ct-DNA) and in-vitro antitumor researches, is introduced. A pyridyl cation is introduced to a porphyrin ring through modification, so the hydrophilicity of lipophilic porphyrin compounds is greatly increased; and the increase of the solubility overcomes a severe defect of the porphyrin derivatives, so the anticancer performance is significantly increased. A result of the study of the application shows that the water-soluble o-nitrophenol-containing copper porphyrin and the Schiff base complex thereof have good in-vitro antitumor activity.

Description

technical field [0001] The invention introduces a class of water-soluble copper porphyrin containing o-nitrophenol and its Schiff base copper porphyrin complex and its synthesis method; the invention also relates to this type of water-soluble copper porphyrin containing o-nitrophenol and its Schiff base The interaction between alkali-copper porphyrin complexes and calf thymus DNA (ct-DNA) and its anti-tumor application in vitro. Background technique [0002] Malignant tumor is currently the second leading cause of human death in the world, seriously threatening human health, and millions of people die of cancer every year. Therefore, the development of new and effective anticancer drugs is a very urgent and important issue in the world today. Since humans used hematoporphyrin as a fluorescent localizer in tumor surgery in the 1950s, porphyrin and its derivatives have attracted great interest from scientists. Due to their good biocompatibility, porphyrin compounds have a sp...
