Electrochemical Study of the Mechanism and Kinetics of Oxygen Reduction Mediated by Anthracycline Antibiotics Adsorbed on Electrode Surface

  • Chapter
Redox Chemistry and Interfacial Behavior of Biological Molecules

Abstract

It is well known that anthracycline antibiotics having an anthraquinone group in the molecule are an important class of widely used antitumor antibiotics1. Their clinical efficacy is limited by severe doserelated cardiotoxicity1,2. It has been considered that these undesirable side effects as well as the clinical benefits result from their ability to shuttle electrons from NADPH-cytochrome P-450 reductase to molecular oxygen that is, in turn, transformed into activated oxygen species such as superoxide anion radical, hydroxyl radical, and hydrogen peroxide1–3. The activated oxygen species have been proposed to play a fatal role in DNA scission4 and peroxidation of mitochondrial membranes5. However, the detailed mechanism is not yet fully understood.

  32. In our case, a dimensionless diffusion coefficient (DNORM = D*ΔTT/(ARR)2) was taken as 0.45 (ΔTT and ΔRR are respectively the time unit and the distance unit). In CV-curve calculations, the potential interval (ΔPOT) was 1 mV and then ΔTT = |Δ POT/v|. In RDV-curve calculations, a dimensionless parameter VZERO (= vo*ΔTT*ΔRR) was taken as 0.001 (vo = 0.51(ω3/ν)1/2) and then ΔTT = (VZERO/vo)2/3(DNORM/D)1/3. Other operations were done in line with the literature14.

  39. The curve-fitting analysis (see the latter section of text) of the CV curves reveals that SOD accelerates the disproportionation reaction rate; kc = 4.65 X 1010 cm3 mol-1 S-1, kdlsp = 7.04 X 104 dm3 mol-1 S-1 at Γt = 7.66 × 10-11 mol cm-2 in the absence of SOD, but kc = 3.67 × 1010 cm3 mol-1 S-1, kdlsp = 5.03 × 105 dm3 mol-1 S-1 at Γt = 6.84 × 10-11 mol cm-2 after the addition of SOD.

  40. In simplified model, the computation time of the CV-curve is greatly reduced and the analytical equation of the RDV curve can be obtained12. Furthermore, a Koutecky-1evich-type linear relation between ip-1 and w1/2 is expected, which has been justified experimentally12.

  41. The kc value decreases with Γt owing to the attractive interaction between adsorbed molecules12. In order to avoid the complexity, the pH dependence kc was examined at a constant Γt as possible (5.7 ± 1.2 × 10-11 mol cm2).

  50. The values of pKa,s, pKa,o, and E°’1 of ADM adsorbed on a mercury electrode have been reported as 6.93, 8.53 and -0.200 V, respectively. Putting these values in Equations (14)-(15) gives the kc value of ADM at pH 7 as 3.86 × 1010 cm3 mol-1 S-1, by using the values of \({\text{k}}_{\text{c}}^{\text{int}}\) and β estimated for 7-DADMN (see Reference 24 and text). This calculated value coincides with the found value.
