Our aim was to determine whether a single transplatin monofunctional adduct, either trans-[Pt(NH3)2(dC)Cl]+ or trans-[Pt(NH3)2(dG)Cl]+ within a homopyrimidine oligonucleotide, could further react and form an interstrand cross-link once the platinated oligonucleotide was bound to the complementary duplex. The single monofunctional adduct was located at(More)
Antisense oligonucleotides (ONs) are designed to hybridize target mRNA in a sequence-specific manner and inhibit gene expression by preventing translation, either by activation of RNase H or steric blockage of the ribosome complex. Second-generation ONs, which possess greater binding affinity for target RNA relative to the isosequential phosphodiester (PO)(More)
In the context of developing an approach to irreversibly and specifically link oligonucleotides to RNA, the purpose of this work was to determine the factors interfering with the rate of the rearrangement of the transplatin 1,3-intrastrand crosslinks into interstrand crosslinks, rearrangement triggered by the formation of a double helix between platinated(More)
