Fabrication, Spectroscopic Characterization, Calf thymus DNA Binding Investigation, Antioxidant and Anti-cancer Activities of Some Antibiotic Azomethine Cu(II), Pd(II), Zn(II) and Cr(III) Complexes
This study was conducted to prepare novel azomethine chelates of Cu(II), Pd(II), Zn(II) and Cr(III) with tri-dentate dianionic azomethine OVAP ligand 2-[(2-Hydroxy-phenylimino)-methyl]-6-methoxy-phenol. The prepared compounds were characterized with the help of elemental analyses, spectral (NMR, FT-IR, UV-vis, mass), conductivity, magnetic and thermal measurements. The spectroscopic data suggest that the parent azomethine ligand bind to the investigated metal ions through both ... إقراء المزيد

Design, Synthesis, Characterization and biological application of some new Schiff Base Cu(II), Pd(II) and Ag(I) Complexes
In this investigation, new Cu(II), Pd(II) and Ag(I) complexes with the tetra-dentate DSPH Schiff base ligand were synthesized. The DSPH Schiff base and its complexes were characterized by using different physicochemical and spectral analysis. The results revealed that the metal ions coordinated with DSPH ligand through azomethine nitrogen and phenolic oxygen. Cu(II), Pd(II) and Ag(I) complexes are present in a ... إقراء المزيد

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
