Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to a simple and effective method for synthesizing azaacridine parent nuclei and its application. Background technique [0002] The discovery of a new acridine compound as the mother core of kinase inhibitors, especially the optimization of the synthesis method, has important research significance. Azacridine derivatives are compounds of great research and application value, which can be widely used in dyes, fluorescence, and medicinal chemistry, and also have certain effects on anticancer. The research on azaacridine compounds is still one of the hot spots in organic synthesis and medicinal chemistry, so the efficient and convenient synthesis of azaacridine derivatives is of great significance. The simple and direct method of synthesizing azaacridine derivatives is still not much reported so far. [0003] The high coplanarity of acridine makes it excellent in anti-tumor, and it...
