Application

MJ33 lithium salt has been used as a peroxiredoxin VI (Prdx6) inhibitor:
  • to study its specific Prdx6 peroxidase activity in vitro and in breast cancer cell line (MCF-7) cell lysates
  • to study its effects on a mouse model of acute lung injury associated with exposure to hyperoxia
  • to study its potential use as a therapeutic agent

Biochem/physiol Actions

MJ33 acts as a non-toxic and potent inhibitor of agonist-induced activation of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase type 2 (NOX2). It also prevents lung injuries associated with lung inflammation in mice. MJ33 is a fluorinated lipid analog, which blocks the enzyme by mimicking the transition state of the substrate.
Novel, active site directed, specific, competitive and reversible inhibitor of phospholipase A2 (PLA2).

Lung injury associated with hyperoxia reflects in part the secondary effects of pulmonary inflammation and the associated production of reactive oxygen species due to activation of NADPH oxidase, type 2 (NOX2). Activation of NOX2 requires the phospholipase A2 (PLA2) activity
Allelic variants of glutathione S-transferase P1-1 differentially mediate the peroxidase function of peroxiredoxin VI and alter membrane lipid peroxidation

The dual-functioning antioxidant enzyme peroxiredoxin VI (Prdx6) detoxifies lipid peroxides particularly in biological membranes, and its peroxidase function is activated by glutathione S-transferase Pi (GSTP). The GSTP gene is polymorphic in humans, with the wild-type GSTP1-1A (Ile105, Ala114) and three
