Synthesis and evaluation of novel sulfamethoxazole-containing 1,8-dioxo-decahydroacridine derivatives: Antimicrobial activity and emission properties

Abstract

A straightforward and efficient method for synthesizing 1,8-dioxo-decahydroacridine derivatives is presented, utilizing a one-pot, three-component condensation reaction involving dimedone, sulfamethoxazole, and aromatic aldehydes. The primary objective of this synthesis is to incorporate the sulfamethoxazole ring into the acridine family structure and examine the antibacterial effects and fluorescence properties of the compounds. The antibacterial activity of the synthesized compounds was evaluated against various gram-positive and gram-negative microorganisms, as well as a fungal strain, using the disk diffusion method, minimum inhibitory concentration determination, and bactericidal assays. Notably, five compounds exhibited potent antibacterial activity against both strains of Bacillus cereus. Furthermore, the influence of pH on the fluorescence emission intensity and absorption spectrum of the synthesized compounds was investigated, revealing that all products displayed fluorescence radiation.
