Synthesis, Spectral Characterization, DNA Interaction, Antimicrobial  and Anticancer Activities  of Some Tri- and Tetra-dentate imine VO(II) Complexes
The new imine ligands were synthesized by the condensation reaction between 2-hydroxynaphthaldehyde or 3-ethoxysalicylaldehyde and _o_-phenylenediamine s in 1:1 molar ratio. The ligands react with vanadyl acetylacetonate in 1:1 molar ratio to give distorted and square pyramidal geometry for tri- and tetra-dentate imine complexes, respectively. All the complexes are non– hygroscopic in nature and stable to the atmosphere. The synthesized ... إقراء المزيد

New palladium (II) and silver (I) Schiff base complexes Promising antibiotic and anticancer agents
Some new complexes derived from Ag (I) and Pd(II) metal ions and HNA imine ligand (L) _i.e. _(2-[(6-Allylidene-2-hydroxy-cyclohexa-1,3-dienylmethylene)-amino]-benzoic acid) have been synthesized and characterized by elemental analyses, molar conductance, magnetic susceptibility measurements, IR, NMR and electronic spectral studies. Moreover, the stability constants of the synthesized complexes were determined spectrophotometrically. On the basis of molar conductance and elemental analyses the complexes ... 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

Three novel Ni(II), VO(II) and Cr(III) mononuclear complexes: Synthesis, structural characterization, DNA interaction, antimicrobial evaluation and anticancer activity
Three novel Cr(III),VO(II) and Ni(II) imine complexes derived from the condensation of 2‐aminophenol (AP) with 2‐hydroxynaphthaldehyde (HN) were synthesized. The prepared HNAP imine ligand and its complexes were investigated via various physicochemical tools. The results suggest that the parent ligand behaves as a dibasic tridentate ONO ligand, when coordinated to Cr(III) in octahedral and to Ni(II) in tetrahedral geometry. In ... إقراء المزيد

DNA interaction, antimicrobial, anticancer activities and molecular docking study of some new VO(II), Cr(III), Mn(II) and Ni(II) mononuclear chelates encompassing quaridentate imine ligand
The present study was conducted to synthesis of some new imine Cr(III), VO(II), Mn(II) and Ni(II) complexes derived from the condensation of 2-amino phenol with 2-hydroxynapthaldehyde were synthesized. The prepared HNPN imine ligand was analyzed by its melting point, IR, 1H NMR and 13C NMR spectroscopies. The investigated HNPN imine complexes were characterized by elemental analysis, FT IR, UV–vis and ... إقراء المزيد
