The Alpha-amino acids Azomethine amino ligands were created by combining L-phenylalanine (P) and DL-tryptophan (T) with 3-methoxysalicylaldehyde (MS) or 4-diethylamino salicylaldehyde (DS). We checked the infrared, 1H, and 13C nuclear magnetic resonance, as well as the melting temperature, for every ligand. Fe (II) and Cu (II) complexes with novel nanoscale structures were generated when the azomethine amino ligands were combined with metal salts. In a dynamic air environment, the separated complexes were studied using thermal analysis (TGA), infrared spectra, ultraviolet-visible spectra, and elemental analysis. From the thermal data, the kinetic and Redfern parameters were calculated. A lack of electrolysis is supported by the low molar conductance values of the complexes. According to the results of the magnetic susceptibility experiments, the complexes under study are paramagnetic. Additionally, spectrophotometric determinations of the produced complexes' stability constants were made. The analytical findings show that amino acid Schiff bases coordinate with Fe (II) and Cu (II) ions in octahedral geometry, according to the general formula [M(HL)2]. and act as dibasic tridentate ONO ligands. liquid water. Using transmission electron microscopy, the size of the produced complexes' particles was measured and found to be nanoscale. Additionally, against some bacteria (+ve), The ligands and their complexes were evaluated for their antibacterial activity against Escherichia coli (-ve) and Micrococcus luteus (+ve), as well as fungi (+ve) such Aspergillus Niger, Candida glabrata, and Saccharomyces cerevisiae. Metal complexes, according to these investigations, are more effective against bacteria and fungi than their equivalent ligands. Through the use of spectrum investigations, viscosity tests, and gel electrophoreses, seeing the complexes' interaction with CT-DNA. The fact that the produced complexes may potentially intercalate with DNA was also uncovered.
