(57) [Problem] To provide a caged compound related to a physiologically active peptide. Kind Code: A1 Abstract: Photosensitive groups removable by irradiation with ultraviolet light include Tyr, Ser, Cys, and Th of bioactive polypeptides. It has a structure linked to the side chain of at least one amino acid selected from the group consisting of r, Lys, Asp and Glu. When a light-sensitive group is linked, the biological activity is reduced or eliminated, and the light-sensitive group is removed. A caged peptide that can be converted to a biologically active polypeptide. |
