The invention provides a reagent which can detect amyloid in vitro and in vivo with high sensitivity using a compound which has affinity with amyloid.
The reagent for detecting amyloid deposited in a biological tissue comprises the compound represented by the following formula (1) or a salt thereof:
wherein A
1
, A
2
, A
3
and A
4
independently represent a carbon or nitrogen,
R
2
is a group selected from the group consisting of a hydrogen, hydroxyl group, carboxyl group, sulfuric acid group, amino group, nitro group, cyano group, non-radioactive halogen substituent, alkyl substituent with 1 to 4 carbon atoms and alkoxy substituent with 1 to 4 carbon atoms, and
R
2
is a radioactive halogen substituent,
provided that at least one of A
1
, A
2
, A
3
and A
4
represents a carbon, and R
1
binds to a carbon represented by A
1
, A
2
, A
3
or A
4
.
本发明提供了一种试剂,可使用与淀粉样物具有亲和性的化合物,在体内外高灵敏度地检测淀粉样物。用于检测生物组织中沉积的淀粉样物的试剂包括下式(1)所表示的化合物或其盐:其中,A1、A2、A3和A4独立地表示碳或氮,R2是从氢、羟基、羧基、硫酸基、氨基、硝基、氰基、非放射性卤素取代基、具有1至4个碳原子的烷基取代基和具有1至4个碳原子的烷氧基取代基组成的群中选择的一种基团,且R2是放射性卤素取代基,但至少A1、A2、A3和A4中的一个表示碳,并且R1结合到由A1、A2、A3或A4表示的碳。
