Evaluation of Antioxidant Property of Quinones and Calculation of their Binding Constant Values with DNA by Electrochemi

Antioxidant property and interaction with Deoxyribonucleic Acid (DNA) of the following four quinones: Mansanone-D, Mansanone-H, Sissoidenone and 4-methoxy dalbergione, were investigated at pH=7.4 using cyclic voltammetry technique. The parameters like binding constant, binding site size and binding free energy value were also determined from voltammetric data. On comparison of binding constant and binding site size among all Quinones, Mansanone-H reveals strong binding capacity (1.04 x 109 ) with DNA than others. The negative sign of binding constants (u0394G) indicate the spontaneity of binding of Quinones with DNA. The electrochemical behavior of DPPH radical was investigated in Dimethyl Sulfoxide (DMSO) and used this radical to determine antioxidant activity of Quinones by cyclic voltammetry method. The scavenging effect of the radical on Quinone was confirmed by the decrease in peak currents with increase in the concentration of Quinones. The binding constant and Gibbs free energy values were calculated from voltammetric data.

Synthesis and electrical conductivity of new organic materials bearing a tetrathiafulvalene unit

New bisymmetric tetrathiafulvalenes (TTFs) containing conjugated substituents (thiophene-π-pyridine) 4-6 were synthesized by the condensation of TTF-thiophenecarboxaldehyde derivatives 1-3 with aromatic amines. Electrochemical studies based on cyclic voltammetry demonstrated, for all these new molecules, electrochemical characteristics favoring the formation of charge transfer complexes (CTCs). Measurements of electrical conductivity at room temperature were carried out on compacted powder, for all the materials obtained. All the CTCs synthesized were found to be semiconductors.
