摘要：Objective Sulfanilamide,sulfadiazine,and dapsone were the first sulfonamides to be used to treat malaria by disrupting the folate biosynthesis process,which is essential for parasite ***,we aimed to synthesize novel N-(2-arylaminophenyl)-2,3-diphenylquinoxaline-6-sulfonamide derivatives through a rational drug design *** All compounds were synthesized by the conventional method,and the products were characterized by spectral analysis(1 H NMR and mass spectrometry).The progression of the reaction was monitored using thin-layer chromatography(TLC).All the derivatives were analyzed for their effective binding mode in the allosteric site of the plasmodium cysteine protease *** and antifungal activities were determined using the broth dilution *** S6(N-(2-thiazol-4 yl)-acetyl-aminophenyl)-2,3-diphenylquinoxaline-6-sulfonamide and S9(N-(1 H-benzo[d]imidazol-2-yl)aminophenyl)-2,3-diphenylquinoxaline-6-sulfonamide formed five hydrogen bonds;S8(N-(2-1 H-imidazol-2 yl)aminophenyl)-2,3-diphenylquinoxaline-6-sulfonamide and S10(N-(1 H-benzo[d]imidazol-5-yl)aminophenyl)-2,3-diphenylquinoxaline-6-sulfonamide formed four hydrogen bonds with the allosteric site of the *** the docking scores and formation of hydrogen bonds with the target enzyme,the novel derivatives were processed for wet lab *** the newly synthesized derivatives were subjected to in vitro antimalarial,antifungal,and antibacterial *** the derivatives exhibited sufficient sensitivity to the Plasmodium falciparum strain compared to the ***,compounds S9 and S10 showed the most potent dual antimicrobial and antimalarial *** also exhibited powerful molecular interactions in molecular docking *** Based on the above results,it was concluded that N-(2-arylaminophenyl)-2,3-diphenylquinoxaline-6-sulfonamide derivatives have excellent biological potential to act as antimalarial,antifungal,
