[Problem] To provide the following: a novel fluorescent probe for detecting a compound, such as glutathione, that contains a —SH group; a detection method using said fluorescent probe; and a detection kit containing said probe.
[Solution] A fluorescent probe for detecting a compound containing an —SH group, wherein the fluorescent probe comprises a compound represented by formula (I) or a salt thereof (In the formula, X represents Si(Ra)(Rb), Ge(Ra)(Rb), Sn(Ra)(Rb), C(Ra)(Rb), or O (wherein Ra and Rb each independently represent a hydrogen atom or alkyl group); R1 represents a hydrogen atom, or 1-4 identical or different substituents independently selected from the group consisting of a cyano group, alkyl group, carboxyl group, ester group, alkoxy group, amide group, and azide group, each of which may be optionally substituted; R2 represents a hydrogen atom, halogen atom, hydroxyl group, cyano group, or an alkyl group, alkynyl group, alkoxy group, aryl, or heteroaryl, each of which may be optionally substituted; R3 and R4 each independently represent a hydrogen atom or 1-3 identical or different substituents independently selected from the group consisting of a hydroxyl group, halogen atom, or an alkyl group, sulfo group, carboxyl group, ester group, amide group and azide group, each of which may be optionally substituted; R5, R6, R7 and R8 each independently represent a hydrogen atom or alkyl group, wherein, R5 or R6, respectively together with R3, may form a ring structure including the nitrogen atoms bonded thereto, or R7 or R8, respectively together with R4, may form a ring structure including the nitrogen atoms bonded thereto).
[问题]提供以下内容:一种用于检测含有-SH基团的化合物(如
谷胱甘肽)的新型荧光探针;一种使用所述荧光探针的检测方法;以及一种含有所述探针的检测试剂盒。
[解]一种用于检测含有-SH基团的化合物的荧光探针,其中所述荧光探针包括由式(I)代表的化合物或其盐 (式中,X代表Si(Ra)(Rb)、Ge(Ra)(Rb)、Sn(Ra)(Rb)、C(Ra)(Rb)或O(其中Ra和Rb各自独立地代表氢原子或烷基);R1 代表氢原子,或 1-4 个相同或不同的取代基,这些取代基独立地选自
氰基、烷基、羧基、酯基、烷氧基、酰胺基和
