glycine-based PNA (pet-PNA) backbone, with 4-amino or 4-guanidino-functionalized pyrrolidine ring, confers constrained conformational flexibility on aegPNA. The oligomers bind to the target DNA and RNA sequences with increased sequence specificity and antiparallel versus parallel orientation selectivity. The easy post-synthetic guanidination gives very good access to the positively charged PNA oligomers
基于N-(吡咯烷-2-乙基)甘氨酸的PNA(pet-PNA)主链4-氨基 或者 4-胍基功能化 吡咯烷环赋予aegPNA受限的构象灵活性。寡聚物以增加的序列特异性和反平行对平行取向选择性结合到靶DNA和RNA序列。易于合成后的胍基化非常容易获得带正电荷的PNA低聚物。
