초록
Chemical modification of siRNA is achieved in a high-throughput manner (96-well plate format) by copper catalyzed azide-alkyne cycloadditions. This transformation can be performed in one synthetic operation at up to four positions with complete specificity, good yield, and acceptable purity. As demonstrated here, this approach extends the current synthetic options for oligonucleotide modifications and simultaneously facilitates the systematic, rapid biological evaluation of modified siRNA.
