In this study we report that amino acridine intermediates 7 and 8 were obtained from the reduction of nitro acridine derivatives 5 and 6 that were synthesized via the condensation of dimedone, p-nitrobenzaldehyde with various amine derivatives, respectively. Then acridine sulfonamide hybrid compounds (918) were synthesized by the reaction of amino acridine 7, 8 with sulfonyl chlorides. The new hybrid compounds were characterized by FT-IR, 1H-NMR, 13C-NMR, and HRMS analyzes. The evaluation of in vitro anticholinesterase action of the synthesized compounds against AChE showed that some of them are potent inhibitors. Among them, compound 17 showed the most potent activity against AChE with an IC50 of 0.14 µM.
