  Stepwise “Click” Chemistry for the Template Independent Construction of a Broad Variety of Cross-Linked Oligonucleotides: Influence of Linker Length, Position, and Linking Number on DNA Duplex Stability

  摘要：

  Cross-linked DNA was constructed by a "stepwise click" reaction using a bis-azide. The reaction is performed in the absence of a template, and a monofunctionalized oligonucleotide bearing an azido-function is formed as intermediate. For this, an excess of the bis-azide has to be used compared to the alkynylated oligonucleotide. The cross-linking can be carried out with any alkynylated DNA having a terminal triple bond at any position of the oligonucleotide, independent of chain length or sequence with identical or nonidentical chains. Short and long linkers with terminal triple bonds were introduced in the 7-position of 8-aza-7-deaza-2'-deoxyguanosine, (1 or 2), and the outcome of the "stepwise" click and the "bis-click" reaction was compared. The cross linked DNAs form cross linked duplexes when hybridized with single stranded complementary oligonucleotides. The stability of these cross linked duplexes is as high as respective individual duplexes when they were ligated at terminal positions with linkers of sufficient length. The stability decreases when the linkers are incorporated at central positions. The highest duplex stability was reached when two complementary cross-linked oligonucleotides were hybridized.
