A novel class of compounds, known as peptide nucleic acids, bind complementary DNA and RNA strands more strongly than the corresponding DNA or RNA strands, and exhibit increased sequence specificity and solubility. The peptide nucleic acids comprise ligands selected from a group consisting of naturally-occurring nucleobases and non-naturally-occurring nucleobases attached to a polyamide backbone, and contain alkylamine side chains.
一种新型化合物,被称为肽核酸,比相应的DNA或RNA链更强烈地结合互补的DNA和RNA链,并表现出增强的序列特异性和溶解性。肽核酸包括从一组中选择的
配体,该组包括天然存在的核碱基和连接到聚酰胺骨架的非天然存在的核碱基,并含有烷基胺侧链。
