(57) [Summary] [Objective] The present invention has excellent affinity for specific organs, particularly cancer, has a fast elimination rate from normal tissues, can reduce phototoxicity, and transforms a metal of a metal complex. Therefore, porphyrin II depending on the application having phosphorescence fluorescence [for photochemical therapy (PDDT)], non-phosphorescence fluorescence [for fluorescence diagnosis (PDDT)] and phosphorescence-free fluorescence [for nuclear magnetic resonance diagnosis (MRI)] Synthesizing and searching for a polymer, PDDT and M The purpose is to provide a drug suitable for RI. [Structure] The present invention comprises a porphyrin dimer obtained through a bishydrazone (spacer) on a porphyrin carrying an aldehyde group or a ketone group and a metal complex thereof. |
