Effect of Acridine with Various Linker Arms Attached to C5 Position of 2′-Deoxyuridine on the Stability of DNA/DNA and DNA/RNA Duplexes
摘要:
Acridine-modified oligodeoxyribonucleotides (ODNs) at the CS-position of a 2'-deoxyuridine via different lengths of linker arms were synthesized. Reaction of 5-(N-aminoalkyl)carbamoylmethyl-2'-deoxyuridines with 9-phenoxyacridine gave the acridine-modified 2'-deoxyuridines which were incorporated into ODNs. The duplexes containing the acridine-modified strands and their complementary DNA or RNA were thermally more stable than that containing the unmodified strand. Thermal stability of the duplexes of the modified ODNs varied depending on the length of the linker arms.
