Title:
COMPOUND FOR PHOTOOXYGENATION CATALYST AND MEDICINAL COMPOSITION CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2023/100942
Kind Code:
A1
Abstract:
[Problem] To develop an artificial catalyst capable of inhibiting aggregation of pathogenic amyloids (tau amyloids) formed by the aggregation of tau proteins, and to provide a prophylactic and therapeutic medicine for amyloid-related diseases using the same. [Solution] It is found that a compound having a structure, wherein an electron acceptor moiety containing a specific thiazole ring is linked to an electron donor moiety by intramolecular conjugation, is useful as a novel biocatalyst capable of selectively oxygenating tau amyloids upon the irradiation with light and preventing the aggregation thereof. It is also found that the aforesaid compound has excellent blood-brain barrier penetration properties and enables the oxygenation of tau amyloids in the brain upon the irradiation with light from the outside of the body.
