Pseudo‐Ligandless Click Chemistry for Oligonucleotide Conjugation

Oligonucleotide tagging for copper-free click conjugation.

Copper-free click chemistry between cyclooctynes and azide is a mild, fast and selective technology for conjugation of oligonucleotides. However, technology for site-specific introduction of the requisite probes by automated protocols is scarce, while the reported cyclooctynes are large and hydrophobic. In this work, it is demonstrated that the introduction of bicyclo[6.1.0]nonyne (BCN) into sy...

Fast, copper-free click chemistry: a convenient solid-phase approach to oligonucleotide conjugation.

Solid-phase oligonucleotide conjugation by nitrile oxide-alkyne click cycloaddition chemistry has been successfully demonstrated; the reaction, compatible with all nucleobases, requires no metal catalyst and proceeds under physiological conditions.

Peptide conjugation via CuAAC 'click' chemistry.

The copper (I)-catalyzed alkyne azide 1,3-dipolar cycloaddition (CuAAC) or 'click' reaction, is a highly versatile reaction that can be performed under a variety of reaction conditions including various solvents, a wide pH and temperature range, and using different copper sources, with or without additional ligands or reducing agents. This reaction is highly selective and can be performed in th...

Click Chemistry background information

Especially biomolecule labeling requires reaction procedures that can be performed under physiological conditions (neutral pH, aqueous solution, ambient temperature) with low reactant concentrations to ensure non-toxic, low background labeling at reasonable time scales while still preserving biological function. Among the plethora of possible reactions only a few generally fit the necessary rea...
