  Remarkable enhancement of binding affinity of Heterocycle-modified DNA to DNA and RNA. Synthesis, characterization and biophysical evaluation of N2-imidazolylpropylguanine and N2-imidazolylpropyl-2-aminoadenine modified oligonucleotides

  摘要：

  Oligonucleotides containing novel N-2-Imidazolylpropylguanine and N-2-Imidazolylpropyl-2-aminoadenine moieties were synthesized and studied for their hybridization and biophysical properties. Interestingly, these heterocycle modified oligonucleotides showed a remarkable enhancement of heteroduplex binding affinity when hybridized to complementary DNA.
