The invention provides a reagent for detecting amyloid 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 mutagenicity.
The reagent for detecting amyloid deposited in a biological tissue comprises the compound represented by the following formula (1) or a salt thereof:
wherein A1, A2, A3 and A4 independently represent a carbon or a nitrogen, and
R3 is a group represented by the following formula:
wherein R1 is a radioactive halogen substituent; m is an integer of 0 to 4; and n is an integer of 0 or 1, provided that at least one of A1, A3, A3 and A4 represents a carbon, and R5 binds to a carbon represented by A1, A2, A3 or A4.
该发明提供了一种用于检测生物组织中淀粉样物质的试剂,该试剂可以使用一种具有与淀粉样物质亲和力且毒性抑制的化合物在体内和体外高灵敏度地检测淀粉样物质。用于检测生物组织中沉积淀粉样物质的试剂包括以下式(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,R3是由以下式表示的基团:其中R1是放射性卤素取代基;m是0至4的整数;n是0或1的整数,但至少有一个A1、A2、A3和A4表示碳,且R5与A1、A2、A3或A4表示的碳结合。
