Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It plays a role in enhancing the selectivity and binding affinity of drug candidates due to the rigid adamantane moiety, which improves metabolic stability and lipophilicity. Also employed in research related to protein-protein interaction inhibitors, where its structure helps in mimicking peptide motifs. Its carboxylic acid and amide functional groups allow for further chemical modifications, making it valuable in medicinal chemistry for building complex bioactive molecules.
