title: [Development of stimulus-responsive amino acids and their application to chemical biology use].
abstract: An understanding of the physiological significance of peptides and proteins is indispensable in the fields of life sciences and drug development. Recently, methods for controlling peptide and protein activities using stimuli such as UV irradiation have been attracting much attention because of their potential for clarifying the physiological roles of the peptides/proteins. In this context, we have developed a stimulus-responsive amino acid that induces peptide-bond cleavage after exposure to a stimulus. Although it has previously been reported that stimulus-responsive units can respond to a specific stimulus, our stimulus-responsive amino acid is potentially applicable to any stimulus simply by changing the protective group. In this review, the design and synthesis of stimulus-responsive amino acids are described. Their applications in chemical biology, including their use for spatiotemporal control of the activity of peptides in living cells, are also reported.
