Description

technical field

[0001] The invention relates to a novel substituted carbazole-imidazolium salt or benzimidazolium salt compound and its preparation method, as well as the anti-tumor application of the pharmaceutical composition in which the compound is an active ingredient. Background technique

[0002] Cancer is a class of diseases that seriously threaten human health. The mainstay currently used to treat cancer is chemotherapy. Most of the chemotherapeutic drugs in clinical use have side effects such as nausea, vomiting, leukopenia, and bone marrow suppression. Therefore, finding highly active, non-toxic or low-toxic anticancer compounds has become an important topic in new drug research.

[0003] As an important five-membered compound, imidazole widely exists in natural product molecules, and also exists in synthetic drug molecules as an important pharmacophore of physiological activity. As an important nitrogen-containing heterocyclic compound, carbazole and its deriv...
