    Reaction of Reduced PQQ (PQQH2) and Molecular Oxygen
    摘要:
    还原型 PQQ(PQQH2)是通过 PQQ 与苯硫酚、1-苄基-1,4-二氢烟酰胺(BNAH)、亚硫酸钠或硼氢化钠反应制备的。研究了分子氧在水溶液中将 PQQH2 氧化成 PQQ 的动力学过程。随着反应的进行,氧化速度逐渐加快,这可能是由于 PQQH2 和 O2 反应产生了 PQQH2 和 H2O2 的副反应。事实上,H2O2 的产率为 PQQH2 的 50%。初始速率与氧气浓度呈一阶关系。pH 值-速率曲线表明反应中的活性物种是 PQQH-。在这一反应中几乎检测不到 O2\ewdot 和 PQQ 本身的自催化作用。此外,还讨论了氧化的机理。

    Kinetic Study of the Antioxidant Activity of Pyrroloquinolinequinol (PQQH2, a Reduced Form of Pyrroloquinolinequinone) in Micellar Solution
    摘要:
    Kinetic study of the aroxyl radical-scavenging action of pyrroloquinolinequinol [PQQH(2), a reduced form of pyrroloquinolinequinone (PQQ)] and water-soluble antioxidants (vitamin C, cysteine, glutathione, and uric acid) has been performed. The second-order rate constants (k(s)) for the reaction of aroxyl radical with PQQH(2) and water-soluble antioxidants were measured in Triton X-100 micellar solution (5.0 wt %) (pH 7.4), using stopped-flow and UV-visible spectrophotometers. The k(s) values decreased in the order PQQH(2) > vitamin C >> cysteine > uric acid > glutathione. The aroxyl radical-scavenging activity of PQQH(2) was 7.4 times higher than that of vitamin C, which is well-known as the most active water-soluble antioxidant. Furthermore, PQQNa(2) (disodium salt of PQQ) was easily reduced to PQQH(2) by reaction of PQQNa(2) with glutathione and cysteine in buffer solution (pH 7.4) under nitrogen atmosphere. The result suggests that PQQ exists as a reduced form throughout the cell and plays a role as antioxidant.

    Kinetic studies on the oxidation of thiols by coenzyme PQQ are carried out under anaerobic conditions. A bell shaped pH-rate profile having a maximum rate at around pKa of the thiol is observed. The rate-determining step changes between acidic and basic sides of the profile indicating the existence of at least one intermediate in the course of the reaction.

    Kinetic studies on the oxidative deamination of amines by coenzyme PQQ are carried out under anaerobic conditions. The reaction is first-order in the appearance of the reduced PQQ and in the total amine concentrations. A large kinetic isotope effect (kH⁄kD=7.24) in the oxidation of α,α-dideuteriobenzylamine indicates that the C–H bond cleavage is a rate-determining step. From the results of formation

    日期:1990.2
    The reaction of coenzyme PQQ with aminoguanidine, which is known as an inhibitor of quinoprotein amine oxidases, was investigated in vitro. The redox reaction predominantly proceeded at pH 10.0 to give PQQH2 (quinol), whereas deactivation of PQQ occurred at pH 6.7 to give the triazine adduct. In the case of semicarbazide or acetohydrazide as the substrate, azo adduct formation was mainly observed even at pH 10.0. Importance of the C-5 carbinolamine-type intermediate a is discussed.
