  Effective Modulation of DNA Duplex Stability by Reversible Transition Metal Complex Formation in the Minor Groove

  摘要：

  Herein we describe the reversible changing of DNA duplex thermal stability by exploiting transition metal complexation phenomena. A terpyridine ligand was conjugated to the N2'-atoms of 2'-amino-2'-deoxyuridine and its locked counterpart 2'-amino-LNA, and these metal-complexing monomers were incorporated into oligodeoxyribonucleotides. Upon addition of varying amounts of transition metal ions, the thermal stability of DNA duplexes containing these terpyridine-functionalized units in different constitutions was affected to different degrees (Delta T-m values = -15.5 to +49.0 degrees C, relative to the unmodified duplex). The most pronounced effects were observed when two complexing monomers were positioned in opposite strands. Addition of 1 equiv of Ni2+ to such a system induced extraordinary duplex stabilization. Molecular modeling studies suggest, as an explanation for this phenomenon, formation of nickel-mediated interstrand linkages in the minor groove. Addition of an excess of metal ions resulted in largely decreased T-m values. Alternating addition of metal ions and EDTA demonstrated reversibility of metal ion-induced changes in hybridization strength, proving that the described approach provides an efficient method for duplex stability modulation.

  Different mono- and bis-terpyridines were synthesized utilizing nucleophilic substitution of 4′-chloro-2,2′:6′,2″-terpyridine. In the case of the mono-functionalized ligands, different functional groups opposite to the metal binding site could be introduced; with the bis-functionalized ligands building blocks for metal-containing polymers with a tailored alkyl-chain length were accessible.

  The solid phase synthesis of PNA oligomers with the internal dipeptide Gly-Phe is presented and the interaction with complementary DNA investigated. UV absorbance melting experiments with different but complementary DNA sequences show that stable PNA x DNA duplexes are only obtained when there is no DNA base opposite the dipeptide unit. Instead, the dipeptide spacer forms a loop-like structure within

  Herein we present the synthesis and thermal stability studies of modified oligonucleotides containing an unlocked nucleic acid (UNA) terpyridine monomer. Incorporation of this monomer into both strands of a DNA duplex allowed reversible thermal stability modulation upon addition or withdrawal of divalent metal ions. A likely explanation of this phenomenon is interstrand complexation between two terpyridine
