ABSTRACT         Background and objectives: Synthesis and characterization of several metal complexes (metal ions: Co2+, Ti4+ and Ce3+) of macroacyclic Schiff base ligand have been reported. The Schiff base ligand is prepared from the condensation reaction of 1, 4-di-(4-fluoro-2-aminophenoxy) butane with salicylaldehyde in ethanol. In addition, antibacterial ...

Background & Aims: Angiogenesis plays an important role in tumor growth and metastasis of cancer; therefore, compounds that inhibit the angiogenesis process can prevent tumor growth. Recently, Schiff base complexes have become important due to properties such as anticancer, anti-oxidant, and the like. In this study, the angiogenesis effect of the copper Schiff base complex on the chorioallantoi...

A selected solid complex of the Schiff base ligand derived from Glutaric anhydride with Cu(II) ion was synthesized and characterized by FT-IR, Electronic, ESR Spectral Analyses, Magnetic susceptibility and Molar Conductance Measurements. The disappearance of ν(O-H) hydroxyl band of the phenolic and the lowering shift of the stretching frequency of the ν(CH=N) azomethine band in the ligand after...

in this paper, we report the synthesis and characterization of a new symmetric macroacyclic schiff base ligand (h2l) and related complexes with different metals. (h2l) was synthesized by the one pot condensation reaction of 2-[2-(2-formyl phenoxy)ethoxy]benzaldehyde and 2-aminobenzenethiol in a 1:2 molar ratio. the acyclic schiff base was characterized by ir, nmr spectroscopy and elemental anal...
