The invention provides a reagent for detecting amyloid deposited in a biological tissue which can detect amyloid in vitro and in vivo with high sensitivity using a compound which has affinity with amyloid and is suppressed in toxicity such as mutagencity. The reagent for detecting amyloid deposited in a biological tissue comprises a compound represented by the following formula (1) or a salt thereof:
wherein A1, A2, A3 and A4 independently represent carbon or nitrogen; R1 is a radioactive halogen substituent; R2 is a group selected from the group consisting of hydrogen, hydroxyl group, methoxy group, carboxyl group, amino group, N-methylamino group, N,N-dimethylamino group and cyano group; and m is an integer of 0 to 2, provided that at least one of A1, A2, and A4 represents a carbon, and R1 binds to a carbon represented by A1, A2, A3 and A4.
本发明提供了一种用于检测沉积在生物组织中的淀粉样蛋白的试剂,该试剂可使用一种与淀粉样蛋白具有亲和力的化合物,在体外和体内高灵敏度地检测淀粉样蛋白,并抑制其毒性(如突变性)。用于检测生物组织中沉积的淀粉样蛋白的试剂包括下式(1)所代表的化合物或其盐:
其中 A1、A2、A3 和 A4 独立地代表碳或氮;R1 是放射性卤素取代基;R2 是选自由氢、羟基、甲氧基、羧基、氨基、N-甲基氨基、N,N-二甲基氨基和氰基组成的组;m 是 0 至 2 的整数,条件是 A1、A2 和 A4 中至少有一个代表碳,且 R1 与 A1、A2、A3 和 A4 所代表的碳结合。
