A cyanine dye having the formula
1
wherein R
1
-R
8
are each independently selected from a group consisting of hydrogen, C
1
-C
6
alkyl group, and C
0
-C
4
alkyl group having a hydrophilic substituent thereon. R
11
and R
12
are chosen to include a free or protected thiol, amine or hydroxyl substituent capable of reacting with a target molecule through a nucleophilic displacement mechanism. The dye is useful in labeling a variety of target molecules. Processes are described for synthesizing suitable heterocyclic and indole derivatives as precursors for the aforementioned cyanine dyes.
一种靛烯染料,其化学式为1,其中R1-R8各自独立选择自氢、C1-C6烷基和具有亲水性取代基的C0-C4烷基。R11和R12被选择为包括具有自由或保护的巯基、氨基或羟基取代基,能够通过亲核置换机制与目标分子反应。该染料可用于标记各种目标分子。还描述了合成适合的杂环和吲哚衍生物作为上述靛烯染料的前体的过程。
