Used in the synthesis of DPP-4 (Dipeptidyl peptidase-4) enzyme inhibitors, a class of drugs for treating type 2 diabetes. This compound acts as an intermediate in the production of drugs that help control blood sugar levels, particularly in the development of pharmaceuticals featuring a benzoazepine structure. Its chiral configuration contributes to stereoselectivity, enhancing efficiency and specificity towards the enzyme target, resulting in fewer side effects and prolonged duration of action. The ester and amide functionalities allow for further modifications in peptidomimetic drug design, improving metabolic stability and binding affinity.
