New constrained PNA monomers containing a substituted thiazolidine or a thiazane ring were synthesized and incorporated in the center of a 9-mer homothymine PNA. The PNA/DNA hybrids stability was studied by UV-melting experiments which showed that the presence of the modified unit destabilizes the PNA/DNA triplexes.
合成了含有取代的噻唑烷或噻嗪环的新的受约束的PNA单体,并将其掺入9聚体高胸腺嘧啶PNA的中心。通过紫外熔融实验研究了PNA / DNA杂合体的稳定性,该实验表明修饰单元的存在使PNA / DNA三链体不稳定。
