Design, Physicochemical Studies and DNA Interaction of Some Complexes
In recent years, great interest has been focused on Fe(II) Schiff bases amino acids complexes as cytotoxic and antitumor drugs. Thus a series of new iron(II) complexes based on Schiff bases amino acids ligands have been designed and synthesized from condensation of 2-hydroxy-1-naphthaldehyde and 5-bromosalicylaldehyde (bs) with α-amino acids ((L-alanine (ala), L-phenylalanine (phala), L-aspartic acid (aspa), L-histidine (his) and L-arginine ... إقراء المزيد

Synthesis, characterization, DFT calculations and biological studies of Mn(II), Fe(II), Co(II) and Cd(II) complexes based on a tetradentate ONNO donor Schiff base ligand
This study highlights synthesis and characterization of a tetradentate ONNO Schiff base ligand namely (1, 1′- (pyridine-2, 3-dimethyliminomethyl) naphthalene-2, 2′-diol) and hereafter denotes as “HNDAP″ and selected metal complexes including Mn(II), Fe(II), Co(II) and Cd(II) as a central metal. HNDAP was synthesized from 1:2 M ratio condensation of 2, 3-diaminopyridine and 2- hydroxy-1-naphthaldhyde, respectively. The stoichiometric ratios of the prepared ... إقراء المزيد

Electrochemical and theoretical quantum approaches on the inhibition of C1018 carbon steel corrosion in acidic medium using some newly phenolic Schiff bases compounds

Electrochemical and theoretical quantum approaches on the inhibition of C1018 carbon steel corrosion in acidic medium using some newly phenolic Schiff bases compounds
Two novel Schiff bases, 5-bromo-2-[(_E_)-(pyridin-3-ylimino)methyl]phenol (HBSAP) and 5-bromo-2-[(E)-(quinolin-8-ylimino)methyl]phenol (HBSAQ) have been synthesized. They have been characterized by elemental analysis and spectroscopic techniques (UV–Vis, IR and NMR). Moreover, the molecular structure of HBSAP and HBSAQ compounds are determined by single crystal X-ray diffraction technique. The inhibition activity of HBSAP and HBSAQ for carbon steel in 3.5% NaCl + 0.1 M HCl ... إقراء المزيد
