Identification of a radical formed in the reaction mixtures of oxidized phosphatidylcholine with ferrous ions using HPLC–ESR and HPLC–ESR–MS

Autor: Hideo Iwahashi, Tomihiro Hirai, Shiroh Kishioka, Kazumasa Kumamoto

Publikováno v: Free Radical Research. 39:987-993

Identification of free radicals was performed for the reaction mixtures of autoxidized 1,2-dilinoleoylphosphatidylcholine (DLPC) with ferrous ions (or DLPC hydroperoxide with ferrous ions) and of DLPC with soybean lipoxygenase using electron spin res

Effects of Some Naturally Occurring Iron Ion Chelators on In Vitro Superoxide Radical Formation

Autor: Tomihiro Hirai, Kazuaki Fukushima, Hideo Iwahashi, Kazumasa Kumamoto

Publikováno v: Biological Trace Element Research. 108:077-086

The effects of some naturally occurring iron ion chelators and their derivatives on the electron transfer from ferrous ions to oxygen molecules were examined by measuring oxygen consumption rates. Of the compounds examined, quinolinic acid, fusaric a

Identification of radicals formed in the reaction mixture of bovine kidney microsomes with NADPH

Autor: Tomihiro Hirai, Shiroh Kishioka, Kazumasa Kumamoto, Hideo Iwahashi

Publikováno v: Journal of biochemistry. 146(4)

In order to explore the mechanism of myoglobinuric renal toxicity, detection and identification of free radicals was performed for the reaction mixtures of bovine kidney microsomes. EPR measurements showed prominent signals for the control reaction m

Identification of a radical formed in the reaction mixture of rat brain homogenate with a ferrous ion/ascorbic acid system using HPLC-EPR and HPLC-EPR-MS

Autor: Kazumasa Kumamoto, Tomihiro Hirai, Shiroh Kishioka, Hideo Iwahashi

Publikováno v: Free radical research. 41(6)

Identification of a free radical is performed for the reaction mixture of rat brain homogenate with a ferrous ion/ascorbic acid system using EPR, high performance liquid chromatography-electron paramagnetic resonance spectrometry (HPLC-EPR) and high

The formation of the 7-carboxyheptyl radical from 13-hydroperoxy-9,11-octadecadienoic acid catalyzed by hemoglobin and myoglobin under anaerobic conditions

Autor: Kazumasa Kumamoto, Tomihiro Hirai, Hideo Iwahashi

Publikováno v: Journal of biochemistry. 133(5)

Methemoglobin (MetHb), oxyhemoglobin (oxyHb), metmyoglobin (metMb), and oxymyoglobin (oxyMb) catalyze formation of the 7-carboxyheptyl and pentyl radicals from 13-hydroperoxy-9,11-octadecadienoic acid. The relative HPLC-ESR peak height of the pentyl
