Used in pharmaceutical research as a building block for synthesizing bioactive molecules, particularly in the development of central nervous system agents. Its rigid bicyclic structure helps improve metabolic stability and target selectivity in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship studies due to its unique three-dimensional shape and ability to mimic peptide bonds. Also utilized in the synthesis of novel receptor ligands where constrained analogs are needed to enhance potency and reduce off-target effects.
