It is intended to provide: a compound useful as an amyloid oxidation catalyst which is applicable in vivo and is applicable not only to Aβ peptides but to other amyloids; and a prophylactic or therapeutic drug for an amyloid-related disease, comprising the same. The present invention provides a benzothiazole compound represented by the following formula (1) wherein X represents a halogen atom; R
1
represents an optionally substituted hydrocarbon group; R
2
represents a hydrogen atom or an optionally substituted hydrocarbon group; R
3
and R
4
are the same or different and each represent a hydrogen atom, an optionally substituted hydrocarbon group, an alkoxy group, a halogen atom, an amino group, a nitro group, or a cyano group; R
2
and R
4
optionally together form an alkylene group; and R
5
represents an anion.
本发明提供以下公式(1)所表示的苯并噻唑化合物,其中X代表卤素原子;R1代表可选择取代的碳氢基团;R2代表氢原子或可选择取代的碳氢基团;R3和R4相同或不同,各自代表氢原子、可选择取代的碳氢基团、烷氧基、卤素原子、氨基、硝基或氰基;R2和R4可选择共同形成烷基基团;R5代表阴离子。旨在提供:一种作为淀粉样蛋白氧化催化剂的化合物,可在体内应用,不仅适用于Aβ肽,还适用于其他淀粉样蛋白;以及包括相同化合物的淀粉样蛋白相关疾病的预防或治疗药物。
