Used in research settings as a potent and selective inhibitor of the enzyme dipeptidyl peptidase-like protein 6 (DPP6), which is implicated in neurological and cardiac functions. Shows promise in studying signaling pathways related to ion channel regulation, particularly Kv4 channels involved in neuronal excitability and heart rhythm. Due to its ability to cross the blood-brain barrier, it is valuable in preclinical studies exploring neurodegenerative diseases and seizure disorders. Also serves as a pharmacological tool to dissect DPP6-mediated biological processes without affecting closely related enzymes like DPP4, reducing off-target effects in experimental models.
