- PDDT Photodynamic Diagnosis and Therapy
- This is a kind of porphyrin compound, such as intravenous injection. It is administered according to the method described above, selectively accumulated and retained in the cancer tissue, and then irradiates with laser light to selectively diagnose only the cancer tissue and destroy it.
- This PDDT has two properties of the porphyrin compound's photosensitizing effect: the longer the porphyrin compound is retained in the cancerous tissue compared to normal cells. This is the therapy used.
- the present inventors have also conducted a search for a more effective porphyrin compound in consideration of various properties possessed by the porphyrin compound, such as affinity for cancer, fluorescence, cell killing, and the like.
- a more effective porphyrin compound in consideration of various properties possessed by the porphyrin compound, such as affinity for cancer, fluorescence, cell killing, and the like.
- porphyrin compounds have been proposed that are useful as photophysicochemical fluorescence diagnostics and therapeutics for cancer, contrast agents for magnetic resonance imaging, and neutron capture therapies.
- the porphyrin compounds proposed so far are not intended to positively exert the DDS effect, and therefore have a problem that they cannot be said to be sufficient to effectively exert the DDS effect. is there.

- the porphyrin compound itself be imparted with high functionality, that is, a cancer affinity as a carrier, a fluorescence property, a cell killing property, etc., after the active substance and the porphyrin compound are covalently bonded.
- radiation therapy is one of the cancer treatment methods, and it is a well-established method of treating cancer together with surgery and cancer chemotherapy.
- this irradiation treatment also has various problems.
- hypoxic cells contain around 20% of hypoxic cells, and these hypoxic cells are 2-3 times more resistant to radiation than normoxic cells. Therefore, the presence of hypoxic cells in the tumor hinders the improvement in the results of radiation therapy, and is a major cause of tumor recurrence.
- drugs have been developed to selectively enhance the radiosensitivity of hypoxic cells.
- ditroazole derivatives having high electron affinity, especially nitroimidazoles are excellent because they have high sensitizing activity to hypoxic cultured cells, have a high metabolic rate, and are stable in vivo. It is considered to be a radiosensitizer, and various nitroimidazole-based drugs such as misonidazole have been developed so far.
- misonidazole one of the representative compounds of hypoxic cell sensitizers, showed about twice the effect of no addition in animal transplantation tumor experiments, due to strong neurotoxicity, administration of an effective amount It has been reported that its sensitizing effect was not observed when applied to humans [Cancer and Chemotherapy, Vol. 8, 1659 (1981)
- this drug had no selective accumulation in cancer cells. Therefore, the present inventors synthesized a porphyrin compound carrying an amino group and obtained a porphyrin metal complex obtained by binding a ditroimidazole-based drug to the compound in order to obtain selective accumulation of such a drug in cancer cells. It has been proposed that this compound is useful as a contrast agent for MRI, or as a sensitizer for PDDT and for radiotherapy (Japanese Patent Application Laid-Open No. 8-67682). However, in producing these porphyrin metal complexes, there was a problem in the synthesis of the porphyrin compound that carries the nitroimidazole-based drug, and practical use was difficult.
- the compound has a functional amino group that can be covalently bound to a nitroimidazole drug introduced into the side chain of the porphyrin
- the distance between the porphyrin skeleton and the amino group is short, and thus the porphyrin nucleus is Under the influence of 7T electrons, the reactivity of the amino group itself was poor.
- the reduction of phototoxicity specific to porphyrin derivatives has not been sufficient. Therefore, the present inventors have proposed that the porphyrin compound has cancer affinity, fluorescence, We studied to obtain a novel vorphyrin complex that could effectively exhibit high functionality such as cell killing properties and that could be applied to DDS therapy and excluding phototoxicity.
