MPO-IN-28 is primarily used in research settings to study the role of myeloperoxidase (MPO) in various biological processes. It is a selective inhibitor of MPO, an enzyme involved in the production of reactive oxygen species (ROS) that play a significant role in inflammation and tissue damage. Researchers utilize MPO-IN-28 to investigate its potential therapeutic effects in conditions where MPO activity is implicated, such as cardiovascular diseases, neurodegenerative disorders, and chronic inflammatory conditions. By inhibiting MPO, this compound helps in understanding the enzyme's contribution to oxidative stress and inflammation, providing insights into potential treatment strategies for diseases linked to MPO dysregulation. Additionally, it serves as a valuable tool in preclinical studies to evaluate the efficacy of MPO inhibition in reducing disease progression and improving outcomes.
