肽核酸(PNA)是一种合成的核酸模拟物,其中糖-磷酸骨架被肽骨架取代。与DNA相比,PNA以更高的亲和力和上级序列选择性与互补DNA和RNA杂交。PNA对核酸酶和蛋白酶具有抗性,并且对蛋白质具有低亲和力。这些性质使PNA成为生物和医学应用的有吸引力的试剂。为了改善PNA的反义和抗基因性质,人们在预组织的概念下探索了许多PNA骨架修饰。本文综述了在N-(2-氨乙基)甘氨酸骨架上带有取代基的手性PNA。介绍了手性聚萘酸的合成、性质和应用。
A peptide nucleic acid (PNA) is a synthetic nucleic acid mimic in which the sugar-phosphate backbone is replaced by a peptide backbone. PNAs hybridize to complementary DNA and RNA with higher affinity and superior sequence selectivity compared to DNA. PNAs are resistant to nucleases and proteases and have a low affinity for proteins. These properties make PNAs an attractive agent for biological and medical applications. To improve the antisense and antigene properties of PNAs, many backbone modifications of PNAs have been explored under the concept of preorganization. This review focuses on chiral PNAs bearing a substituent in the N-(2-aminoethyl)glycine backbone. Syntheses, properties, and applications of chiral PNAs are described.
