Design, synthesis and in vitro antibacterial activities of methyl-4-((substituted phenyl) [6H-indolo (2,3-b)quinoxalin-6-yl]methyl-amino)benzoate derivatives

A series of new methyl-4-((substituted phenyl) [6H-indolo (2,3-b)quinoxalin-6yl]methylamino)benzoate derivatives have been synthesized and assayed for their antibacterial activity on 9 different bacterial strains. Among the screened compounds 2e–2g exhibited potent inhibitory activity compared to standard drug employed, worth further investigation.
