α–β Chimeric oligo-DNA bearing intercalator-conjugated nucleobase inside the linker sequence remarkably improves thermal stability of an alternate-stranded triple helix
摘要:
Novel alpha-beta chimeric oligodeoxynucleotides bearing an intercalator-conjugated nucleobase located at the internal 4-nt linker region were synthesized, and their triplex-stabilizing property was examined. The triple helical DNA formed between the modified chimera DNA and double-stranded DNA exhibited remarkable thermal stability; however, the position of the intercalator-conjugated nucleobase had little influence on the stability. Among the examined, modified chimera DNA bearing the two intercalator-conjugated nucleobases at adjacent positions exhibited the highest stability. (C) 2004 Elsevier Ltd. All rights reserved.
