Synthesis and alternate-stranded triple helix forming ability of novel anthraquinone modified alpha-beta chimeric DNA
Department of Chemistry, Gunma University, 1-5-1 Tenjincho, Kiryu, Gunma 376-8515, Japan
A series of novel
-ß chimeric oligonucleotides bearing an anthraquinone-conjugated non-nucleosidic backbone were synthesized as a triplex-forming oligonucleotide (TFO). UV-melting experiments revealed that the obtained modified chimera TFOs form remarkably stable alternate-stranded triplex almost regardless to the stereochemistry of the incorporated non-nucleosidic backbone unit.
