Abstract
ABSTRACT The synthesis of 2,2′-bipyridinyl-2′-deoxyuridine metal-chelator nucleosides (Bipy-dU) with either ethynyl or ethylenyl linkers was now been accomplished. These new nucleosides will permit the construction of a number of corresponding metallo-DNA conjugates where many types of metals can be complexed to the 2,2′-bipyridinyl chelator group and the resulting metallo-dU conjugates incorporated into DNA oligonucleotides. Additionally this paper also reports the synthesis of a di-N-alkylated bipyridinediiumyl-2′-deoxyuridine nucleoside (Bipy2+-dU) with an ethylenyl linker. The Bipy2+-dU nucleoside was found to decompose under basic conditions precluding its use in standard automated DNA-synthesis by the phosphoramidite method. No such restrictions apply to the two Bipy-dU nucleosides reported here for use as metal chelators.
