Abstract

The invention discloses a compound having a radiosensitization function and an application of the compound. The compound has an anti-proliferation effect on p53 wild tumor cells and p53 mutant tumor cells and can reduce TG2 gene expression of two kinds of cells while no remarkable change occurs to p53 gene expression. The compound and IR are subjected to combined treatment, two kinds of cells have remarkable cell apoptosis increasing and remarkable cell cycle arresting, the radiosensitivity is remarkably improved, and the TG2 gene expression is remarkably reduced. Therefore, the compound has a remarkable radiosensitization function on the p53 wild tumor cells and the p53 mutant tumor cells and is expected to substantially improve the tumor radiotherapy effect after being applied to tumor radiotherapy as an active ingredient of a radiosensitizer and particularly applied to p53 signal path activation enhanced tumor radiotherapy after excessive activation of a p53 signal path and ionizing radiation induction.

Description

Technical field [0001] The invention belongs to the fields of biomedicine and pharmacy, and specifically relates to a compound with radiosensitization effect and its application. Background technique [0002] Cancer is a major health problem all over the world. Lung cancer is the most common malignant tumor, its incidence is 12.4% of the tumor incidence, and the mortality rate is as high as 17.8%. In China, the smoking behavior that easily leads to lung cancer has not been effectively controlled, and coupled with the environmental deterioration factors in recent years, the incidence and death of lung cancer have shown an upward trend year by year. [0003] Radiotherapy is one of the conventional treatments for cancer, and the same is true for lung cancer. Although the current radiotherapy technology continues to develop, the probability of tumor radiotherapy failure is still high, the main reason is the existence of tumor cell radiation tolerance. Therefore, radiosensitivity is ...
