Used as a key intermediate in the synthesis of antidiabetic drugs, particularly in the development of DPP-4 inhibitors for type 2 diabetes treatment. Its structure enables high selectivity and potency in enzyme inhibition, improving glycemic control. Commonly employed in pharmaceutical research to optimize drug candidates for better metabolic stability and oral bioavailability. Also utilized in structure-activity relationship (SAR) studies to enhance binding affinity and reduce off-target effects.
