  摘要：

  合成了一系列基于2,3-二甲基-3-（4-磺丁基）-3 H-吲哚-5-磺酸的单反应性水溶性茚二羰花青染料。这些染料除了在偶氮烯端基中还包含（最多3个）磺基烷基外，还包含两个芳族磺基。研究了磺丁基的数量和位置对溶液中游离染料以及与抗体（IgG）结合后染料的光谱性质和光稳定性的影响。这些染料的最大吸收在649和653 nm之间，摩尔吸收率在240,000和256,000 M -1  cm -1之间，最大发射波长在668至672 nm之间，游离形式的荧光量子产率在28％至32％之间，与IgG结合时可达到43％。这些染料与磺基基团的数量无关，在水中浓度高达5×10 -5  M时没有聚集。发现磺基烷基基团的数量与IgG共轭染料的荧光量子产率和光稳定性直接相关。

  Disclosed are cyanine dyes that are useful for labelling and detecting biological and other materials. The dyes are of formula (I): in which at least one of groups R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 R 11 , R 12 , R 13 and R 14 is -L-M or -L-P, where L is a linking group, M is a target bonding group and P is a conjugated component, and at least one of groups R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 and R 10 comprises fluorine. The use of cyanine dyes substituted by fluorine and having additional substitution with three or more sulphonic acid groups for labelling biological target molecules results in a labelled product in which there is reduced dye-dye aggregation and improved photostability, compared with cyanine dyes having no such substitutions. The dyes of the present invention are particularly useful in assays involving fluorescence detection where continual or repeated excitation is a requirement, for example in kinetic studies, or in microarray analyses where microarray slides may need to be reanalysed over a period of days.

  揭示了一种对于标记和检测生物和其他材料有用的青霉素染料。该染料的化学式为（I）：其中R1、R2、R3、R4、R5、R6、R7、R8、R9、R10、R11、R12、R13和R14中的至少一个是-L-M或-L-P，其中L是连接基团，M是目标键合基团，P是共轭组分，并且R3、R4、R5、R6、R7、R8、R9和R10中的至少一个包含氟。通过用氟取代并具有三个或更多磺酸基团的青霉素染料标记生物靶分子，得到的标记产品中减少了染料-染料聚集并提高了光稳定性，与没有这种取代的青霉素染料相比。本发明的染料在涉及荧光检测的分析中特别有用，其中需要连续或重复激发，例如在动力学研究中，或在微阵列分析中，微阵列玻片可能需要在数天内重新分析。

  Disclosed are reactive polyfluoro benzoxazole polymethine dyes that are useful for labelling and detecting biological and other materials. The dyes are of formula (I): in which X is selected from the group consisting of —O—, —S— and at least one of groups R 1 and R 2 is the group -L-R x or -L-R p , where L is a linking group, R x is a group suitable for covalent attachment of the dye to a component and R p is a component; and at least one of groups R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 and R 10 comprises fluorine. The use of polymethine dyes substituted by fluorine and having additional substitution by sulphonic acid groups, for labelling biological target molecules results in a labelled product in which there is reduced dye-dye aggregation and improved photostability, compared with cyanine dyes having no such substitutions.
