Synthesis of an oxyamino-containing phenanthroline derivative for the efficient preparation of phenanthroline oligonucleotide oxime conjugates
摘要:
A phenanthroline derivative bearing an oxyamino linker was efficiently prepared from commercial 5-nitro-1,10-phenanthroline. The subsequent reaction with an oligonucleotide containing an aldehyde either at the 5' end or the 3' end afforded, in good yield, the phenanthroline-oligonucleotide conjugates through oxime bond formation.

A convenient method for the conjugation of ruthenium complex on oligonucleotides and peptides through chemoselective oxime linkage is reported. Novel Ru(II) complexes sustaining an aminooxy containing ligand were prepared and efficiently coupled with the oligonucleotides and peptides functionalized with the complementary reactive aldehyde group. The method described herein could be a useful tool for preparing a broad range of metal complex-oligonucleotide and peptide conjugates. (C) 2007 Elsevier Ltd. All rights reserved.
