  摘要：

  6H-Indolo[2,3-b]quinoxaline was studied as a covalently bound heteroaromatic intercalator. Six monomers were synthesized and incorporated into DNA oligonucleotides. Through a study of linker length dependence it was concluded that the linker between the oligo and the intercalator must consist of at least five C atoms in order to stabilize a DNA duplex. An intercalator with a 2 '-deoxy-D-riboside linker to the oligo could also stabilize a DNA/RNA duplex, while (S)-4-(6-methylindolo[2,3-b]quinoxalin-3-ylmethoxy)-butane-1,2-diol was able to stabilize both DNA/DNA, DNA/RNA and a DNA/LNA duplex. Mismatch studies revealed a huge sensitivity to the C-C mismatch at the 5'-site of the intercalator. (c) 2006 Elsevier Ltd. All rights reserved.
