Design and synthesis of new N-(5-Trifluoromethyl)-1H-1,2,4-triazol-3-yl benzenesulfonamides as possible antimalarial prototypes

Abstract

A rational approach was used to synthesize a new set of 15 1H-1,2,4-triazol-3-yl benzenesulfonamide derivatives with the aim of developing new antimalarial lead compounds. These derivatives were prepared in yields between 50% and 62%, and their structures were elucidated using IR, 1H-, 13C-, 19F-NMR, MS and elemental analysis. A docking study based on sulfonamides previously used against malaria identified trifluoromethyl-substituted derivatives to be the best lead compounds for new antimalarial drug development. © 2011 by The Authors.
