Used in research settings as a potent and selective inhibitor of the enzyme dipeptidyl peptidase-4 (DPP-4), making it a candidate for studying glucose metabolism and insulin regulation. It has been investigated for its potential in developing treatments for type 2 diabetes due to its ability to enhance incretin activity, which helps lower blood glucose levels. Its high selectivity reduces off-target effects, supporting its use in preclinical studies to understand DPP-4 inhibition mechanisms and therapeutic efficacy.
