Abstract

The invention discloses an aza-acridine aromatic ring derivative as well as a preparation method and application thereof, belonging to the technical field of medicaments. A structural formula of the aza-acridine aromatic ring derivative is as shown by a formula I, wherein m is 0 or 1, n is 1 or 2, and R is one of H, CH3 and NO2. The obtained aza-acridine aromatic ring derivative disclosed by the invention has synergistic activities in tumor chemotherapeutic medicaments, and is small in cytotoxic effect. Because the aza-acridine aromatic ring derivative is low in cytotoxic effect and generally has synergistic effects on the tumor chemotherapeutic medicaments, the aza-acridine aromatic ring derivative is of a novel synergist of the chemotherapeutic medicaments, has an important improvement effect on tumor chemotherapy, and also has important economic values.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to an azaacridine aromatic ring derivative and a preparation method and application thereof. Background technique [0002] Tumor chemotherapy drugs have toxic and side effects on normal cells of the body, and the treatment costs are high. Reducing the amount of chemotherapeutic drugs can reduce the cost of treatment and potentially reduce their toxic side effects on normal cells. Acridine is a common mother nucleus of chemically synthesized drugs, and its derivatives have different pharmacological effects due to their different structures. Synthesizing and screening out low-toxic new synthetic drugs with synergistic activity of tumor chemotherapy drugs will have an important role in improving cancer chemotherapy, and also have important economic value, providing a new solution for the attenuation and efficiency enhancement of tumor chemotherapy.
