3-Substituted 5-Nitroindole derivatives and labeled oligonucleotide probes containing them

摘要

The current invention restates substituted nitroindole nucleosides as both terminal as well as internal building blocks of labeled oligonucleotide probes for the detection, analysis and quantitation of nucleic acids. The substituent comprises a linker and a detectable group or a linker and a reactive group for post synthesis coupling. These modified nucleosides grant access to a wide application area. These new substituted nitroindole nucleosides can be used as labeling reagents for the facile preparation of e.g. optimized hybridization probes, simple probes, Taqmanprobes or molecular beacon probes.
