Design,  Synthesis, Structure Inspection,  Biological Screening,  and DNA Binding Study of  Some New VO(II), Pd (II) and Ag(I)  Chelates incorporating Tri-dentate Chemo Sensor Imine Ligand
The present study was conducted to synthesis of some new imine VO(II), Pd(II) and Ag(I) complexes derived from 2-[(2-Hydroxy-naphthalen-1-ylmethylene)-amino]-benzoic acid were synthesized. The prepared imine ligands were analyzed by their melting point, IR, 1H NMR and 13C NMR spectroscopy. The investigated imine complexes were characterized by elemental analysis, FT IR, Uv-vis and thermal analysis (TGA) in air from ambient temperature ... إقراء المزيد

Design, Characterization, DNA Interaction and antimicrobial of novel copper(II) Schiff base amino acid complexes
Five novel copper(II) complexes derived from the condensation between 5-bromosalicyaldhyde (bs) and α-amino acids (L-alanine, L-phenylalanine, L-aspartic acid, L-histidine and L-arginine) were synthesized and characterized by their elemental analyses, thermogravemetric analysis, IR, electronic spectra and conductance and magnetic measurements. Moreover, the stoichiometry and the stability constants of the prepared complexes have been determined spectrophotometrically. The Results indicated that the Schiff ... إقراء المزيد

Nano sized ternary Cu(II) complexes Encompassing Salicylaldehyde Derivatives and Amino Acids as an Effective Strategy for Antimicrobial Activity Improvement and DNA Interaction
A series of ternary Cu(II) complexes encompassing ONO donor Schiff base amino acid ligands were synthesized from condensation of 3–methoxysalicylaldehyde (MS) or 4-diethylamino salicylaldehyde (DS) with α-amino acids (L-phenylalanine (Phe), L-histidine (His), DL-tryptophan (Trp)) as primary ligand and 2, 4-bipridyl (DP) as secondary ligand. All the prepared compounds were characterized by melting points, decomposition temperatures, elemental analysis, UV-Vis, IR spectra, ... إقراء المزيد
