LRRK2-IN-1 is primarily used in research settings to study the role of leucine-rich repeat kinase 2 (LRRK2) in various biological processes. It is a potent and selective inhibitor of LRRK2, making it a valuable tool for investigating the kinase's involvement in diseases such as Parkinson's disease. Researchers utilize this compound to explore the mechanisms underlying LRRK2-associated pathologies, including its impact on neuronal function and autophagy. Additionally, LRRK2-IN-1 is employed in preclinical studies to evaluate the therapeutic potential of LRRK2 inhibition, aiding in the development of targeted treatments for neurodegenerative disorders. Its ability to modulate LRRK2 activity also makes it useful for studying other conditions where LRRK2 dysregulation may play a role, such as inflammatory diseases and cancer.
