Abstract: | A series of 15 sulphonyl urea derivatives (7a-7o) containing various heterocyclic substitu-ents were synthesized, characterized by elemental analysis, IR, 1H NMR and 13C NMR spectra and evaluated for in vitro antibacterial and antifungal activity. Molecular docking studies were performed to calculate docking scores and to propose the binding mode of sulphonyl urea derivatives with E. coli beta-ketoacyl-acp synthase III, a key enzyme that catalyzes the initial step of fatty acid biosynthesis via a type II dissociated fatty acid synthase. The re-sults from this study revealed that the derivatives 7g, vj, 7l and 7o can become possible lead molecules for antimicrobial drug discovery. In vitro antimicrobial studies confirmed that the derivatives 7g, 7j, 7l and 7o have demonstrated better activity than the others Se sintetizó una serie de 15 derivados de sulfonilurea (7a-7o) que contiene diversos sustitu-yentes heterocíclicos, caracterizados por análisis elemental, IR, RMN de 1H y de 13C espec-tros RMN, y se evaluaron in vitro para actividad antibacteriana y antifúngica. Se realizaron estudios de acoplamiento molecular para calcular las puntuaciones de conexión y proponer el modo de unión de derivados de sulfonilurea con E. coli beta-cetoacil-ACP sintasa III, una enzima clave que cataliza la etapa inicial de la biosíntesis de ácidos grasos a través de un tipo II disociado ácido graso sintasa. Los resultados de este estudio revelaron que los derivados de 7 g, vj, 7l y 7o pueden convertirse en posibles moléculas de plomo para el descubrimiento de fármacos antimicrobianos. Los estudios in vitro confirmaron que los derivados de 7g, 7j, 7l y 7o han demostrado una mejor actividad antimicrobiana que los otros |
