吡咯喹啉醌Pyrroloquinoline quinone(PQQ)

Pyrroloquinoline quinone (PQQ) serves as a redox cofactor for Glucose dehydrogenase, functioning as an orthocyclic antioxidant amidst diverse environmental stressors and nutrient-rich conditions in both prokaryotic and eukaryotic organisms. This compound is exclusively synthesized by microbes and is essential for catalyzing the conversion of glucose to gluconic acid and 2-ketogluconic acid by both gram-positive and gram-negative bacteria. PQQ exhibits properties as an anti-neurological, anti-degenerative, anti-melanogenic, and anti-cancer agent, owing to its antioxidative properties which involve the scavenging of free radicals.

Applications

1. Incorporated as a constituent within nanocurcumin formulation (NCF), to investigate its therapeutic potential in alleviating hypoxia-induced stress in hypertrophied cardiomyocytes.

2. Employed to evaluate its efficacy in mitigating restrained oxidative stress and hepatic fibrogenesis in mouse models.

3. Shown to possess noteworthy blood-brain barrier permeability and minimal toxicity, thereby capable of delaying neurodegeneration and mitigating cognitive deficits in AD mouse models.

4. Utilized as a benchmark in fluorescence analysis.
