Pyrroloquinoline Quinone (PQQ) and Rheumatic Diseases

International Journal of Medical Science and Pharmaceutical Research
Introduction: Pyrroloquinoline quinone (PQQ) is a redox cofactor with antioxidant and immunomodulating actions implicated in protection of mitochondria and modulation of inflammation pathways. Oxidative stress is centrally involved in the onset of rheumatic diseases, such as RA, thus PQQ may be considered as a candidate for new therapeutic strategies.

Complex and charge transfer between TiO2 and pyrroloquinoline quinone

, 2006
Pyrroloquinoline quinone (PQQ) forms a tridentate complex with coordinatively unsaturated titanium atoms on the surface of similar to 4.5 nm TiO2 particles; an association constant of K = 550 M-1 per Ti(IV)(surf) has been determined.

Simple immobilization of pyrroloquinoline quinone on few-walled carbon nanotubes

, 2020
Pyrroloquinoline quinone (PQQ) was immobilized on glassy-carbon electrodes (GCE) modified with single-walled carbon nanotubes (SWCNT), few-walled carbon nanotubes (FWCNT) and carbon black (Vulcan XC72R). Modified electrodes were prepared by drop-casting.

Pyrroloquinoline Quinone (PQQ) Nutritional Status in Humans after Oral Supplementation

The FASEB Journal, 2010
PQQ is a novel growth factor. Reproduction and mitochondrial metabolism are impaired in animals fed diets devoid of PQQ. However, little is known about PQQ functional parameters in humans. In a randomized study, 10 subjects ingested PQQ and were examined at daily/weekly intervals.
