Synthesis of Imidazolo Analogues of the Oxidation−Reduction Cofactor Pyrroloquinoline Quinone (PQQ)
The Journal of Organic Chemistry, 2004Parallel syntheses of 2-hydro-, 2-methyl-, and 2-methoxycarbonylimidazo-7,9-dimethoxycarbonyl analogues of the oxidation-reduction cofactor pyrroloquinoline quinone [4,5-dihydro-4,5-dioxo-1H-pyrrolo[2,3-f]quinoline-2,7,9-tricarboxylic acid] have been developed. The properties of the imidazolo analogues in relation to the corresponding pyrrole analogues

Effects of pyrroloquinoline quinone (PQQ) on skin wound healing in mice
SurgeryWound healing is a dynamic process that begins following the destruction of the skin's normal anatomy. This study evaluated effects of pyrroloquinoline quinone on skin wounds in mice.Thirty-six male mice were randomly divided in to 3 groups: (1) Sham group, where wounds were created but no treatment was administered; (2) Soybean oil, where soybean oil ...

A subchronic oral toxicity study on pyrroloquinoline quinone (PQQ) disodium salt in rats
Food and Chemical Toxicology, 2015A subchronic oral toxicity study on pyrroloquinoline quinone (PQQ) disodium salt was performed in rats. Sprague-Dawley rats were randomly divided into four groups (10 rats/sex/group) and administered with PQQ disodium salt at doses of 0 (control), 100, 200 and 400 mg/kg bw/day by gavage for 13 weeks.

Pyrroloquinoline quinone (coenzyme PQQ) and the oxidation of SH residues in proteins.
BioFactors (Oxford, England), 1992Pyrroloquinoline quinone (PQQ) catalyzes the oxidation of cysteamine at neutral pH with a second order rate constant K2 = 0.45 M-1 s-1. The reduction of PQQ was monitored by absorption and fluorescence spectroscopy, whereas the oxidation of cysteamine to cystamine was followed by titration with 5,5'-dithiobis(2-nitrobenzoic acid).

Crystal Structure of a Ytterbium(III)–Pyrroloquinoline Quinone (PQQ) Complex
Pyrroloquinoline quinone (PQQ) is a redox-active quinone-based cofactor best known for its role in bacterial alcohol dehydrogenases, including a subset of lanthanide-dependent enzymes discovered in recent years. To gain further structural insight into lanthanide-PQQ coordination chemistry, we report the crystal structure of [YbPQQ(HJonathan Gutenthaler-Tietze +2 more
