Abstract

The invention relates to the technical field of medicine chemistry, in particular to a heteroaromatic ring compound with a thiosemicarbazone structure unit and a preparation method and application ofthe compound. The heteroaromatic ring compound with the thiosemicarbazone structure unit is chelated with metal ions in gastric cancer cells to form a stable complex, and accordingly the proliferationactivity of the gastric cancer cells MGC803 is inhibited. It is proved through a result of an embodiment that compared with a compound 3-AP, the heteroaromatic ring compound with the thiosemicarbazone structure unit has good proliferation inhibition activity on the gastric cancer cells MGC803.

Description

technical field [0001] The invention relates to the technical field of medicinal chemistry, in particular to an aromatic heterocyclic compound containing a thiosemicarbazone structural unit and a preparation method and application thereof. Background technique [0002] Malignant tumors, especially gastric cancer, are a serious threat to human health. In addition to the development and improvement of early preventive diagnosis techniques for tumors, the development of new and efficient anti-tumor drugs is the most basic means of treating tumors. Studies have shown that transition metal ions such as FeII / III, CuI / II and ZnII play an extremely important role in the metabolic process of normal cells, and are the basic guarantee for cell growth and proliferation. Excessive metal ions will cause cytotoxicity, while insufficient may cause Leading to metabolic disorders or cell death, metal ions participate in various biochemical reactions in cells, especially play an important role...
