Diapocynin, a proposed NADPH oxidase (NOX) inhibitor, is an anti-inflammatory and antioxidant agent. Diapocynin attenuates oxidative damage and neuroinflammatory responses in animal model of Parkinson’;s disease. Diapocynin reverses deficient motor coordination in LRRK2R1441Gtg mice of PD.
Diapocynin is a covalent dimer of apocynin, and a functional metabolite of the same. It is generated by neutrophil activation via myeloperoxidase-mediated oxidation. Studies show that diapocynin has greater neuroprotection compared to apocynin.
