Abstract

The invention belongs to the field of chemical medicine, and discloses a benzo nitrogen hetero-aromatic ring compound represented by formula I, or pharmaceutically acceptable salts, stereisomers, racemic compounds, prodrugs, or solvates thereof. The invention also discloses applications of the benzo nitrogen hetero-aromatic ring compound in preparation of drugs used for treating diseases caused byprotein kinase and/or nicotinamide phosphoribosyltransferase abnormal activity. The benzo nitrogen hetero-aromatic ring compound represented by formula I or the salts thereof possess tyrosine kinaseand Nampt double inhibition effects, can be taken as effective components in treatment or prevention of tumor, are excellent in curative effect, and low in toxic or side effect.

Description

technical field [0001] The invention belongs to the field of chemistry and medicine, and relates to a benzoazepine aromatic ring compound, a preparation method and application thereof, a pharmaceutical composition containing the compound and the application thereof. Background technique [0002] Some malignant tumors, such as lung cancer, liver cancer, rectal cancer and leukemia, have become one of the most important factors that seriously endanger people's life happiness and affect residents' health index because of their difficult early detection, early diagnosis and early treatment. As far as the current status of cancer treatment is concerned, the overall treatment effect is poor. Therefore, the development of targeted therapeutic drugs is an urgent scientific research problem that researchers need to solve. In recent years, although some new targeted new drugs such as tyrosine protein kinase inhibitors have been developed and marketed, they are far from meeting the gro...
