Abstract
o-Bromobenzoic acid was found to promote copper-dependent reactive oxygen species formation from molecular oxygen, resulting in DNA base modification and backbone cleavage. The oligonucleotide conjugate bearing 5-(4'-aminopropyl-sulfomoyl)-2-bromobenzoic acid as a reactive group was synthesized and DNA cleavage activity of this oligonucleotide conjugate was tested on a model deoxyoligonucleotide.
