  Zwitterionic Oligonucleotides: A Study on Binding Properties of 2′-O-Aminohexyl Modifications

  摘要：

  2'-O-Aminohexyl side chains provide excellent conditions for zwitterionic interstrand and intrastrand interactions of oligonucleolides. 2'-O-Aminoalkylatedphosphoramidites of adenosine and uridine were synthesized and incorporated in increasing number into homo adenosine and homo uridine/thymidine dodecamers, respectively. CD spectra of these dodecamers with complementary sense DNA exhibited a B-DNA type structure. While duplex stability values of all tested oligonucleotides were lower than those Of the native oligonucleotides, they were significantly higher than those of 2'-O-heptyl modified oligonucleotides. The destabilization amounted to 0.9, 1.5, and 2.7 degrees C per modification for 2'-O-aminohexyl adenosine, 2'-O-aminohexyl uridine, and 2'-O-heptyl adenosine substitutions. These findings are pointing to a duplex stabilizing effect of the interaction of side chain amino groups with backbone phosphoric acid.
