  Oligonucleotide derivatives in nucleic acid hybridization analysis. III. Synthesis and investigation of properties of oligonucleotides, bearing bifunctional non-nucleotide insertion

  摘要：

  Non-nucleotide phosporamidites were synthetized, having a branching backbone with different positions for functional groups. Phosphoramidite monomers obtained contain intercalator moiety, 6-chloro-2-methoxyacridine, and additional hydroxyl residue protected with dimethoxytrityl group or with the tert-butyldimethylsilyl group for post-synthetic modification. Oligothymidilates containing one or more modified units in different positions of the sequence were synthesized. The melting point and thermodynamic parameters of the formation of complementary duplexes formed by modified oligonucleotides were defined (change in enthalpy and entropy). The introduction of intercalating residue causes a significant stabilization of DNA duplexes. It is shown that the efficiency of the fluorescence of acridine residue in the oligonucleotide conjugate significantly changes upon hybridization with DNA.
