Fluorescent labeling agent, photodynamic therapeutic agent and phthalocyanine

摘要

Problem to be solved: to provide a phthalocyanine compound having a characteristic excellent in fluorescence intensity, light resistance and singlet oxygen generation ability suitable for fluorescent labeling and photodynamic therapy in the wavelength range of 800 nm or more.Solution: a fluorescent labeling agent containing a salt of a phosphorus containing phthalocyanine compound in which a phthalocyanine compound is coordinated to a phosphorus atom of a phosphorus compound represented by the following formula and a fluorescent labeling agent containing a salt of the phosphorus containing phthalocyanine compound and a photodynamic therapeutic agent.R5o-p-or6Aliphatic hydrocarbon group- P (= O) r7r8C (= O) R9- S (= O) 2r10 or - sir11r12r13;R7 and R8 are hOhAliphatic hydrocarbon groupAromatic hydrocarbon groupAlkoxyl or aryloxy groups;R9 is hAliphatic hydrocarbon groupAromatic hydrocarbon group;R10 is ohAliphatic hydrocarbon group or aromatic hydrocarbon group;R11-r13 are aliphatic hydrocarbon groups or aromatic hydrocarbon groups.)No selection
