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

Antimicrobial and anticancer activities of cobalt (III)-hydrazone complexes: Solubilities and chemical potentials of transfer in different organic co-solvent-water mixtures
The present study focused on the measurement of the solubilities and the calculation of the chemical potentials of transfer of Co(III)-hydrazone complexes in mixtures of water and ethyl alcohol (EtOH), isopropyl alcohol (_i_-PrOH), or _tert_-butyl alcohol (_t_-BuOH) at 298 K, using the assumption that dm mq Ph4As+ = dm mq BPh4- (TATB). A comparison between the chemical potentials of transfer ... 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

Facile Synthesis, X-ray structure of new Multi-Substituted Aryl Imidazole ligand, Biological Screening and DNA binding of itsCr(III), Fe(III) and Cu(II) coordination  compounds as potential antibiotic and anticancer drugs
A simple highly adjustable and effective synthesis of aryl imidazole ligand HL namely (2‐(1‐butyl‐4,5-diphenyl‐1H‐imidazol‐2‐yl)(4-bromophenol) was discussed where it was prepared by cyclo condensation of 5-Bromo-2-hydroxybenzaldehyde, benzil and Butan-1-amine. Three new Cr(III), Fe(III) and Cu(II) complexes of aryle imidazole ligand were synthesized. The multi-substituted aryl imidazole ligand (HL) and its complexes were characterized by using physicochemical and IR and electronic spectral ... 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
