Abstract: Provided are a compound which is useful as an in vivo applicable, amyloid-oxygenating catalyst selective for amyloid and applicable not only to an Aβ peptide but also to other amyloids and a drug containing the compound for preventing and/or treating amyloid-related-diseases.Disclosed is a boron-dipyrrin complex represented by the following formula (1) wherein X1 and X2 are the same or different and each represent a halogenoalkyl group or a halogen atom; R1 represents a hydrogen atom, an alkyl group, or a group represented by formula (b); R2 and R6 are the same or different and each represent a hydrogen atom or a halogen atom; R3, R4, R5, and R7 are the same or different and each represent a hydrogen atom, a halogen atom, or an alkyl group; R8 represents a hydrogen atom or —(CH2)l—(Y)m—(CH2)n—Z wherein Y represents —CO—, —CONH—, or a triazole ring, Z represents a carboxyl group, a sulfonic acid group, or a —CO-peptide residue, l and n each represent an integer of 1 to 6, and m represents 0 or 1; R9 and R10 are the same or different and each represent a hydrogen atom, an alkyl group, an alkoxy group, a halogen atom, an amino group, a nitro group, or a cyano group; and R8 and R10 together optionally form an alkylene group.
