Used as a key intermediate in the synthesis of thrombin inhibitors, particularly in the development of anticoagulant drugs. It plays an important role in medicinal chemistry for constructing heterocyclic systems that enhance binding affinity to serine proteases. Its structure allows for efficient derivatization, making it valuable in optimizing pharmacokinetic properties of drug candidates targeting cardiovascular diseases. Also employed in research settings for designing enzyme inhibitors with improved selectivity and metabolic stability.
