Abstract

Pseudo-complementary oligonucleotide analogues and mimics provide novel opportunities for targeting duplex structures in RNA and DNA. Previously, a pseudo-complementary A-T base pair has been introduced. Towards sequence unrestricted targeting, a pseudo-complementary G-C base pair consisting of the unnatural nucleobases n6-methoxy-2,6-diaminopurine (previously described in a DNA context) and N4-benzoylcytosine is now presented for design of pseudo-complementary PNA oligomers (pcPNAs).

一种新型伪互补PNA G-C碱基对。
伪互补寡核苷酸类似物和模拟物为靶向RNA和DNA的双工结构提供了新的机会。在此之前,我们已经介绍了伪互补的a - t碱基对。为了实现序列不受限制的靶向,伪互补G-C碱基对由非天然核碱基n6-甲氧基-2,6-二氨基嘌呤(以前在DNA环境中描述过)和n4 -苯甲酰胞嘧啶组成,现在提出了伪互补PNA寡聚物(pcPNAs)的设计。
