(57) [Summary] [Object] The present invention aims to reduce phototoxicity by being fast in excretion rate from normal tissue, having high single component property, stability, water solubility, and excellent affinity for specific organs, particularly cancer. In addition, it is possible to synthesize and search for a porphyrin derivative capable of using a titanium sapphire laser (wavelength of 670 nm or more and 600 nm or less), and to provide a photosensitizer suitable for photophysicochemical diagnostic treatment (PDT). To aim. [Structure] The present invention comprises an alkoxyporphyrin amino acid derivative and a metal complex thereof, and a porphyrin derivative obtained by adding or condensing to an aldehyde group-supporting chlorin which is synthetically derivatized from blood-derived protoporphyrin. |
