Kinetics of Alkaline Hydrolysis and DNA Interaction of Iron Complexes
Air and moisture stable coordination compounds of some first transition metals such as Cr (III), VO (II), Ni(II) and Mn(II) with newly designed tri- and tetra-dentate imine ligands (HNAP, HNPN and ESPN) were synthesized. Tridentate imine ligands (HNAP, ESAP) were synthesized by reacting 2-hydroxynapthaldehyde (HN) with 2-aminophenol (AP), whereas tetra-dentate imine ligands (HNPN and ESPN) were prepared by reacting 2-hydroxy-1-napthaldehyde ... إقراء المزيد

Recent advances in synthesis, characterization and biological activity of nano sized Schiff base amino acid M (II) complexes
Azomethine amino ligands derived from the condensation of 3-methoxysalicylaldehyde (MS) or 4-diethylaminosalicylaldehyde (DS) with α-amino acids (L-phenylalanine (P) and DL-tryptophan (T)) were synthesized. All ligands were analyzed by IR, 1H NMR, 13C NMR and their melting points. Interaction of the obtained azomethine amino ligands with metal salts produced novel nano sized Fe (II) and Cu (II) complexes. The isolated complexes ... إقراء المزيد

Reactivity Trends and Kinetic Inspection of Hydroxide Ion Attack and DNA Interaction on Some Pharmacologically Active Agents of Fe(II)  Complexes at Different Temperatures
The reactivity of few novel high‐spin Fe(II) complexes of Schiff base ligands derived from 2‐hydroxynaphthaldehyde and some variety of amino acids with the OH− ion has been examined in an aqueous mixture at the temperature range from 10 to 40°C. Based on the kinetic investigations, the rate law and a plausible mechanism were proposed and discussed. The general rate equation ... إقراء المزيد

Kinetic study of the hydroxide ion attack on and DNA interaction with high spin iron(II) Schiff base amino acid chelates baering ONO donors
Kinetic study of some novel high spin Fe(II) complexes of Schiff base ligands derived from 5-bromsalicyaldehyde and amino acids with the OH− ion and DNA has been carried out. Based on the kinetic data, the rate law and a plausible mechanism were proposed. Kinetic data of the base catalyzed hydrolysis imply pseudo first-order double stage process due to the presence ... إقراء المزيد
