In order to examine the probable mechanism of the reaction of benzyl viologen dication
(BzV2+) and its reduced forms with bCD, cyclic voltammograms were digitally simulated.
and is also in clinical development in several other in dication
areas, including the treatment of ARDS, myocardial infarction, and for transplant support, including prevention of Graft versus Host Disease and liver trans plant support.
By removing another electron from the positive polaron, a positive bipolaron or a dication
with charge +2 and no spin are localized over several repeating units.
Initially, the laccase triggers ABTS oxidation that occurs with the formation of radical cation [ABTS.sup.+*] with a correspondence with first peak oxidation [E.sub.pcI], in cyclic voltammetry profile, in approximately + 0.17 V; the second oxidation peak, [E.sub.pcII], represents the oxidation of the radical cation forming the dication
ABTS2+ in approximately + 0.73 V (Figure 2).
In the toxicity due to PQ, the PQ dication
([PQ.sup.2+]) accepts an electron from a reductant to form the PQ monocation radical ([PQ.sup.+]), which subsequently reacts rapidly with [O.sub.2] to produce superoxide ([O.sub.2.sup.*-]).
Figure 2 denotes the relationship of preme- dication
period to the pH metery of group O".
The second oxidation peak is irreversible probably due to the deactivation of the generated dication
, which is highly reactive, by the nucleophilic impurities present in the medium.
