In addition to their C8-NH-arylamine-dG counterparts, C8-N-acetylarylamine adducts of 2′-deoxyguanosine (2′-dG) play an important role in the possible induction of chemical carcinogenesis. A new synthetic pathway of this adduct type using different aromatic amines has been developed following most probably an electrophilic amination reaction. These adducts can be converted into the corresponding phosphoramidites for incorporation into oligonucleotides.
除了 C8-NH-arylamine-dG 对应物外,2′-脱氧
鸟苷(2′-dG)的 C8-N-acetylarylamine 加合物在可能诱发
化学致癌方面也发挥着重要作用。利用不同的芳香胺,很可能是通过亲电胺化反应,开发出了这种加合物类型的新合成途径。这些加合物可转化为相应的
磷酰胺,用于掺入寡核苷酸中。
