Synthesis, spectral characterization, antimicrobial activity and docking studies against DNA Gyrase-A of new 4-chloro-3- nitrobenzene sulfonamide derivatives

Özet

A series of new 4-chloro-3-nitrobenzene sulfonamide derivatives 3(a-j) were synthesized from 4-chloro-3- nitrobenzene sulfonyl chloride by reacting various amino acid esters and amines 2(a-j) in high yields. The structures of all the synthesized compounds were characterized by the IR, NMR (1H & 13C), mass and elemental analyses. Further, all the synthesized compounds were tested for the antimicrobial activity and docking studies were carried out with DNA Gyrase-A. Most of the compounds showed good to moderate antimicrobial activities and binding affinity towards DNA Gyrase-A structure
