Abstract:

Unsymmetrical tetradentate Schiff base Fe(III) and Cu(II) complexes were prepared by the coordination of some unsymmetrical tetradentate Schiff base ligands with CuCl2·2H2O or FeCl3·6H2O. The obtained complexes were characterized by ESI-MS, IR, and UV-Vis. The spectroscopic data with typical signals are in agreement with the suggested molecular formulae of the complexes. Their cyclic voltammetric studies in acetonitrile solutions showed that the Cu(II)/Cu(I) and Fe(III)/Fe(II) reduction processes are at (−)1.882–(−) 1.782 V and at (−) 1.317–(−) 1.164 V, respectively.

Abstract:

Oral squamous cell carcinoma (SCC) is one of the most predominant tumors worldwide and the present treatment policies are not enough to provide a specific solution. We aimed to assess the cytotoxic effect of Cu(II)–Mn(II) Schiff base tetradentate complex alone or in combination with cisplatin against squamous cell carcinoma cell line (SCCs) in vitro. Oral-derived gingival mesenchymal stem cells (GMSCs) were used as control. The cell viability was assessed by MTT assay. IC50 values were calculated. Evaluation of apoptosis and DNA damage were performed. In addition, the expression of pro-apoptot

Abstract:

The study of transition metal complexes involving high denticity ligands has achieved importance in recent decades. This type of ligand can coordinate with metal centers and give products with unusual geometries and coordination numbers. Because group-4 complexes have many special properties and applications, group-4 tetradentate Schiff-base monomers have been synthesized and further applied to polymer chemistry. Several monomers have been synthesized successfully including dichloro (N,N$\sp\prime$-ethylenedisalicylidene-1,2-phenylenediaminato) titanium(IV), Ti(salen)Cl$\sb2$; bis(N,N$\sp \pri
