Synthesis, Characterization, and Antibacterial Activity two New Schiff Bases devired from (E)-2-(((2-aminoethyl) imino) methyl) phenol (E)-2-(4-aminobut-1-enyl)-5-methylbenzamine

In this study two new Schiff base ligands were synthesized, characterized and antibacterial activities were investigated against Escherichia coli, Pseudomonas aeruginosa, Bacillus cereus, Salmonella typhimurium, and Staphylococcus aureus. (E)-2-(4-aminobut-1-enyl) phenol derived from Ethylene diamine and Salicyldehye. (E)-2-(4-aminobut-1-enyl)-5-methylaniline derived from 4-dimethyl amino benzaldehyde and Ethylene di-amine. The Schiff bases were characterized by elemental analysis and FT-IR. The Schiff base ligands were screened in vitro for their antibacterial inhibiting potential by using Disc diffusion method. The results indicated that the Schiff base I have showed biological activity against E coli. The main purpose of the study was to compare the inhibitory effect of these Schiff bases with commercial antibiotics Ciprofloxacin and Erythromycin to introduce new varieties of antibacterial agents.
