The biological activity of these products were as antibacterial agents against three species of human pathogenic bacteria such asEscherichia coli, Staphylococcus aureusandKlebsiella sp. Nearly 50% of these compounds showed reasonable activity against the bacterial species investigated and we found that the antibacterial activity is dependent on the molecular structure of the compounds.
