Fmoc-β-Cyclohexyl-L-alanine is widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a building block for incorporating β-cyclohexyl-L-alanine into peptide chains, enhancing their structural diversity and stability. This compound is valuable in the development of peptide-based drugs, where it can improve pharmacokinetic properties such as bioavailability and resistance to enzymatic degradation. Additionally, it is utilized in research to study peptide interactions and conformational behavior, aiding in the design of novel therapeutic agents and biomaterials. Its application extends to the synthesis of peptidomimetics, which mimic natural peptides but offer enhanced stability and activity.
