Bis-functionalized fullerene-dibenzo[18]crown-6 conjugate: synthesis and cation-complexation dependent redox behavior
(Royal Society of Chemistry, 2003-07-21)A one-step synthesis of bis-pyrrolidine functionalized fullerene-dibenzo[18]crown-6 conjugate and its metal cation complexation to the crown ether entity dependent redox behavior is reported. -
Continuous spectrophotometric assays for dopamine beta-monooxygenase based on two novel electron donors: N,N-dimethyl-1,4-phenylenediamine and 2-aminoascorbic acid
(Elsevier, 1991-09-02)Based on the novel chromophoric electron donors, N,N-dimethyl-1,4-phenylenediamine (DMPD) and 2-amino-2-deoxy-L-ascorbic acid (2-aminoascorbic acid), two sensitive, convenient, and continuous spectrophotometric assays for ... -
Enhanced photocurrents via redox modulation by fluoride binding to oxoporphyrinogen in a zinc porphyrin-oxoporphyrinogen surface modified TiO2 supramolecular solar cell
(Royal Society of Chemistry, 2011-06-07)A novel approach for improving photocurrent in a supramolecular solar cell, composed of zinc porphyrin-oxoporphyrinogen (ZnP-OxP) surface-modified TiO(2), by redox tuning through fluoride anion binding to the redox active ... -
Immobilization and electrochemical redox behavior of cytochrome c on fullerene film-modified electrodes
(Elsevier, 2005-04-01)Two different fullerene film-modified electrodes were prepared and used for surface immobilization and electrochemical property investigation of horse heart cytochrome c (cyt c). Both a pristine fullerene film and ... -
Molecular triads composed of ferrocene, C60, and nitroaromatic entities: electrochemical, computational, and photochemical investigations
(John Wiley and Sons, 2002-12-27)Synthesis and physicochemical characterization of a series of molecular triads composed of ferrocene, C(60), and nitroaromatic entities are reported. Electrochemical studies revealed multiple redox processes involving all ... -
P(450)/NADPH/O(2)- and P(450)/PhIO-catalyzed N-dealkylations are mechanistically distinct
(American Chemical Society, 2005-02-09)A high-valent iron-oxo species analogous to the compound I of peroxidases has been thought to be the activated oxygen species in P450-catalyzed reactions. Spectroscopic characterization of the catalytically competent ... -
pH-induced alteration and oxidative destruction of heme in purified chromaffin granule cytochrome b(561): implications for the oxidative stress in catecholaminergic neurons
(American Chemical Society, 2003-04-01)The transmembrane hemoprotein, cytochrome b(561) (b(561)), in the neuroendocrine secretory vesicles is shown to shuttle electrons from the cytosolic ascorbate (Asc) to the intravesicular matrix to provide reducing equivalents ... -
The reduction of membrane-bound dopamine beta-monooxygenase in resealed chromaffin granule ghosts. Is intragranular ascorbic acid a mediator for extragranular reducing equivalents?
(American Society for Biochemistry and Molecular Biology, 1995-11-17)The role of internal and external reductants in the dopamine beta-monooxygenase (D beta M)-catalyzed conversion of dopamine to norepinephrine has been investigated in resealed chromaffin granule ghosts. The rate of ... -
Substrate specificity of ascorbate oxidase: unexpected similarity to the reduction site of dopamine beta-monooxygenase
(Elsevier, 1994-09-30)A series of ascorbate derivatives has been used to examine the specificity of the reduction site of ascorbate oxidase. Replacement of the 6-OH group of ascorbic acid with either hydrogen or bromine does not alter the ...
