Photosensitizer, protein cleaving agent, protein cleaving method, sugar molecule cleaving agent, sugar molecule cleaving method, and photodynamic therapeutic agent

摘要

[PROBLEMS] To provide a novel photosensitizer, methods of cleaving a protein and cleaving a sugar molecule with light irradiation, and a protein-cleaving agent and sugar molecule-cleaving agent for use in these methods. [MEANS FOR SOLVING PROBLEMS] A compound represented by the following general formula (I) or a salt thereof generates active oxygen upon light irradiation and functions to cleave a protein and sugar molecules. The compound or salt is hence useful in applications such as a photosensitizer, protein-cleaving agent, sugar molecule-cleaving agent, and photodynamic therapeutic agent. [Chemical formula 1] (I) (In the formula, RSUB1/SUB to RSUB8/SUB each is hydrogen or a hydroxylated substituent, provided that at least one of RSUB1/SUB to RSUB8/SUB is a hydroxylated substituent.)
