Abstract

Benzotriazole-1-acetic acid was coupled with amino acid methyl esters/ dipeptides/ tripeptides/tetrapeptides in the presence of DCC as a coupling agent and NMM as a base under continuous stirringfor 36 hrs. The reactions were monitored by TLC. The newly synthesized compounds were analyzedand the structures were confirmed by IR and 1H NMR spectroscopy. The synthesized compounds weretested against bacterial strains Bacillus subtilis, Staphylococcus aureus and Escherichia coli by usingciprofloxacin as standard in the concentration of 20?g/mL. All the compounds were also tested againstfungal strains Candida albicans, Aspergillus niger and Penicillium expansum by using fluconazole asstandard in the concentration of 10?g/mL. Compounds 1, 2, 3 and 4 were found to be more potent antimicrobial compounds.
