Hairpin Mimics with Phenanthroline- and Bipyridine-Derived Linkers
摘要:
The synthesis and structural stabilities of modified oligonucleotide hairpins containing phenanthroline- and bipyridine-modified loops is reported. Phenanthroline (phen) and bipyridine (bipy) building blocks were synthesized, incorporated into DNA-oligonucleotides, and analyzed by thermal denaturation experiments. The so modified oligomers were found to form stable hairpin structures. Tm values were not affected by divalent transition metals.

Simple, non-nucleosidic phenanthroline- and phenanthrene derivatives have been synthesised and incorporated into oligodeoxynucleotides. Complementary strands containing the modified building blocks in opposite positions form stable hybrids. Thermal denaturation experiments show that the double strands containing the phenanthroline derivatives are more stable than the ones with the corresponding phenanthrenes
