  Versatile Site-Specific Conjugation of Small Molecules to siRNA Using Click Chemistry

  摘要：

  We have previously demonstrated that conjugation of small molecule ligands to small interfering RNAs (siRNAs) and anti-microRNAs results in functional siRNAs and antagomirs in vivo. Here we report on the development of an efficient chemical strategy to make oligoribonucleotide-ligand conjugates using the copper-catalyzed azide-alkyne cycloaddition (CuAAC) or click reaction. Three click reaction approaches were evaluated for their feasibility and suitability for high-throughput synthesis: the CuAAC reaction at the monomer level prior to oligonucleotide synthesis, the solution-phase postsynthetic "click conjugation", and the "click conjugation" on an immobilized and cornpletely protected alkyne-oligonucleotide scaffold. Nucleosides bearing 5'-alkyne moieties were used for conjugation to the 5'-end of the oligonucleotide. Previously described 2'- and 3'-O-propargylated nucleosides were prepared to introduce the alkyne moiety to the 3' and 5' termini and to the internal positions of the scaffold. Azido-functionalized ligands bearing lipophilic long chain alkyls, cholesterol, oligoamine, and carbohydrate were utilized to study the effect of physicochemical characteristics of the incoming azide on click conjugation to the alkyne-oligonucleotide scaffold in solution and on immobilized solid support. We found that microwave-assisted click conjugation of azido-functionalized ligands to a fully protected solid-support bound alkyne-oligonucleotide prior to deprotection was the most efficient "click conjugation" strategy for site-specific, high-throughput oligonucleotide conjugate synthesis tested. The siRNA conjugates synthesized using this approach effectively silenced expression of a luciferase gene in a stably transformed HeLa cell line.
