Design, Synthesis and Antibacterial Evaluation of (E)-N-(3-methyl-6-nitroquinoxalin-2-yl)-4-((1-phenylethylidene) Amino) Benzenesulfonamide Derivatives

Antibiotic resistance has increased the need to investigate new antibacterial scaffolds. This study synthesized a series of quinoxaline sulfonamide Schiff base derivatives, designated 1a–h, and evaluated their antibacterial activity against selected bacterial strains. The compounds were prepared through the reaction o...

Rational Design and Synthesis of Benzothiophene–Quinoxaline–Oxadiazole Conjugates Targeting Bacterial and Fungal Pathogens

The escalating threat of antimicrobial resistance demands new therapeutic agents. This study reports the synthesis, characterization, and biological evaluation of novel benzothiophene–quinoxaline–oxadiazole hybrids. The core framework was constructed via phase‐transfer catalysis to yield compound 1a , which under...
