Pyrroloquinoline Quinone Is an Effective Senomorphic Agent to Target the Pro-Inflammatory Phenotype of Senescent Cells. [PDF]
As a natural senomorphic agent, PQQ targets the intracellular molecule. HSPA8 of senescent cells, resulting in significantly reduced expression of the SASP. PQQ holds prominent potential to delay chronological aging and ameliorate age‐related conditions by acting as an effective senomorphic agent.

Determination of PQQ in quinoproteins with covalently bound cofactor and in PQQ‐derivatives [PDF]
Application of the so‐called hexanol extraction procedure for PQQ determination, originally based on detachment of the cofactor from quinoproteins and conversion into PQQ‐5,5‐dihexyl ketal, leads in several cases to a number of products due to uncontrollable esterification.

PQQ-linked extracellular glucose oxidation and chemotaxis towards this cofactor in rhizobia [PDF]
The presence of the pyrroloquinoline quinone (PQQ)-dependent glucose dehydrogenase in several strains of different Rhizobium species and of Bradyrhizobium japonicum was investigated. It was found that most strains were only able to synthesize the apo-enzyme, whereas in three strains, Rhizobium meliloti 102F34 and Bradyrhizobium japonicum strains ...

Pyrroloquinoline quinone (PQQ) is the organic cofactor in soybean lipoxygenase‐1 [PDF]
Treatment of soybean lipoxygenase‐1 (SLO) with phenylhydrazine (PH) induced inactivation and a maximum (350 nm) in the absorption spectrum of the enzyme. To detach the product having this absorption maximum, proteolysis was required. The product appeared to be the C(5) phenylhydrazone of pyrroloquinoline quinone (PQQ).
