The invention provides reagents and fluorescent metal complexes derived therefrom, for labelling target biological materials. The reagents are compounds having the following general formula: in which X1 and X2 are the same or different and are selected from hydrogen and the group: Q and Q′ (if present) are the same or different and are selected from —N═CHR7— and —N═N—;Y1, Y2 (and Y3 if present) are independently selected from the group consisting of —OH, —NH2, —SH and —COOR8 where R8 is selected from H and C1-C4 alkyl; Z1, Z2 and Z3 independently represent the atoms necessary to complete one ring, two fused ring, or three fused ring aromatic or heteroaromatic systems; at least one of groups R1 to R4 (and R5, R6 and R7 if present) is the group -E-F where E is a spacer group and F is a target bonding group; and any remaining groups R1 to R4 (and R5, R6 and R7 if present) are independently selected from the group consisting of: hydrogen, halogen, amide, hydroxyl, cyano, nitro, optionally substituted amino, sulphydryl, sulphonate, sulphate, phosphonate, phosphate, quaternary ammonium, carboxyl, carbonyl, C1-C6 alkoxy, acrylate, vinyl, styryl, aryl, heteroaryl, C1-C6 alkyl, and aralkyl groups.
该发明提供了试剂和由此衍生的荧光金属配合物,用于标记目标生物材料。该试剂是具有以下一般式的化合物:其中X1和X2相同或不同,选择自氢和群体:Q和Q'(如果存在)相同或不同,选择自—N═CHR7—和—N═N—;Y1、Y2(和Y3,如果存在)独立选择自—OH、—NH2、—SH和—COOR8的群体,其中R8选择自H和C1-C4烷基;Z1、Z2和Z3独立表示完成一个环、两个融合环或三个融合环的芳香或杂环系统所必需的原子;R1到R4中的至少一个群体(如果存在R5、R6和R7)是-E-F群体,其中E是一个间隔群体,F是一个目标结合群体;剩余的任何群体R1到R4(如果存在R5、R6和R7)是独立选择自氢、卤素、酰胺、羟基、氰基、硝基、可选择取代的氨基、巯基、磺酸盐、硫酸盐、膦酸盐、磷酸盐、季铵盐、羧基、羰基、C1-C6烷氧基、丙烯酸酯、乙烯基、苯乙烯基、芳基、杂芳基、C1-C6烷基和芳基烷基群体的群体。
