Understanding the Inhibitory and Antioxidant Effects of Pyrroloquinoline Quinone (PQQ) on Copper(II)-Induced α-Synuclein-119 Aggregation.

ACS Chemical Neuroscience, 2022
Parkinson's disease (PD) is associated with the aggregation and misfolding of a-synuclein (a-syn) protein in dopaminergic neurons. The misfolding process is heavily linked to copper dysregulation in PD.

Derivatisierung von PQQ und PQQ‐Triester für den Nachweis von PQQ

Helvetica Chimica Acta, 1993
Formation of derivatives of PQQ and PQQ‐Triester for the Detection of PQQPQQ is an organic redox/cofactor found in a class of enzymes called quinoproteins. It has been reported that materials like milk, egg yolk, vinegar, beer, serum, urine, and biological tissues contain little amounts of PQQ.

PQQ, the elusive coenzyme

Trends in Biochemical Sciences, 1989
The recently discovered redox coenzyme, PQQ (methoxatin), is widely distributed. Quantitation of protein-bound PQQ has been difficult, but unique redox cycling reactions, which reflect its striking biological properties, reveal trace amounts. PQQ is a potential target for drugs.
