Synthesis, antimicrobial and docking studies of some novel (N1E, N2E)-N1, N2-bis(2-amino-3,5-dibromobenzylidene)-aryl-1,2-diamines

Abstract

The diamino derivative is utilized to synthesize various substituted derivatives, which are characterized by IR and NMR. The antibacterial properties of synthesized compounds have been explored. Novel (E)-4,6-dibromo-N1- (4-substitutedbenzylidene)benzene-1,2-diamine derivatives ( 1-6 ) have been obtained in good yields from 2-amino-3,5-dibromobenzaldehyde and 4-substituted benzene-1,2 diamines in a single pot synthesis. The antimicrobial activity of the synthesized compounds have been screened against different strains such as Staphylococcus aureus , Bacillus subtilis , Streptococcus pyogenes , Klebsiella pneumoniae , Escherichia coli and compared with Ciprofloxacin as a standard and compound 6 shows significant activity against Staphylococcus aureus . The docking study results also support the antimicrobial activity data.
