A new method for the formation of covalently linked DNA conjugates is
described. The method involves installation of a 5´-hydroxylamine
nucleophile onto synthetic DNA and condensation with a suitable electrophilic
carbonyl compound to form an oxime linkage. Various protection strategies for
the hydroxylamine group and their merits are discussed and the formation of an
oligonucleotide–peptide conjugate is described.
描述了一种形成共价连接的DNA共轭物的新方法。该方法涉及将5´-羟胺亲核试剂安装到合成DNA上,并与合适的亲电羰基化合物缩合形成肟键。讨论了羟胺基团的各种保护策略及其优点,并描述了寡核苷酸-肽共轭物的形成。
