ANTIBACTERIAL ACTIVITES OF SOME NEW AMINO ACID-SCHI BASES

ABSTRACT Some new insert ignore into journalissuearticles values(N-indolidene-DL-glycine, N-indolidene-DL-alanine and N-indolidene-DL-valine); amino acid-Schiff bases were prepared by the condensation of indole-3-carboxaldehyde and DL-glycine, DL-alanine and DL-valine and characterized by elemental analysis, IR, UV-Vis, 1H-NMR spectroscopy and 13 C-NMR spectroscopy. Antimicrobial activities of the amino acid-Schiff bases have been tested against four different microorganisms.   Key Words: Amino acid, schiff bases, antibacterial activity, microorganism.
