Design, Synthesis, anticancer activity and molecular docking studies on a series of VO(II), Cr (III), Mn(II) and Ni(II) Mononuclear Chelates incorporating Quaridentate imine ligand as antitubulin agents
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 ... Read more

Three novel Ni(II), VO(II) and Cr(III) mononuclear complexes: Synthesis, structural characterization, DNA interaction, antimicrobial evaluation and anticancer activity

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 ... Read more

Sonochemical synthesis, DNA binding, antimicrobial evaluation and in vitro anticancer activity of nano-sized Cu(II), Co(II) and Ni(II) chelates as precursors for metal oxides
Three new nano sized Cu(II), Co(II) and Ni(II) complexes of imine ligand derived from the condensation of 2-amino-3-hydroxypyridine and 3-methoxysalicylaldehyde have been prepared and investigated using various chemical techniques such as NMR, elemental analysis, molar conductance, IR, electronic spectra, TGA and magnetic momentmeasurements. The obtained chemical analysis data showed that the synthesis of 1:1 (metal:ligand) ratio and octahedral geometry was ... Read more
