linker, has been used to prepare a novel chiral peptide nucleic acid (cPNA) with (2R,4R) stereochemistry using solid phase methodology. The homothymine decamer cPNA binds to complementary polyadenylic acid to form a 2:1 hybrid with high affinity and specificity according to UV and CD studies, whereas no binding to the corresponding polydeoxyadenylic acid was observed.
D-脯氨酸的合成子在4位被胸腺嘧啶取代,在N处被柔性的氨乙基接头取代,已被用于通过固相方法制备具有(2R,4R)立体化学的新型手性肽核酸(cPNA)。根据UV和CD研究,高胸腺嘧啶十聚体cPNA与互补的聚腺苷酸结合形成具有高亲和力和特异性的2:1杂合体,而未观察到与相应的聚脱氧腺苷酸的结合。
