Hydroxylamines directly react with nucleobases in genomic DNA, and the damaged nucleobases induce genetic mutations by forming non-canonical base pairs with natural bases. In contrast, some nucleoside analogues containing hydroxylamine and its related derivatives are known to possess antiviral and anticancer activities by mimicking natural nucleosides. In addition, oligonucleotides with phosphate backbones modified with hydroxylamines show nuclease resistance required for oligonucleotide therapeutics.
This chapter provides the fundamental functions and the applications of hydroxylamine, oxime and hydroxamic acid groups on nucleic acids, consisting of four contents (1. Reactions of hydroxylamine and O-methylhydroxylamine with nucleobases, 2. Nucleoside and nucleotide analogues consisting of hydroxylamine, oxime and hydroxamic acid groups, 3. A series of oligonucleotides modified at backbone and sugar moieties with these functional groups, and 4. Application for the detection and quantification of DNA lesions by aminooxy probes). Novel nucleic acids will be developed by understanding potential functions of hydroxylamine and its related derivatives.
