Replacement of the negatively charged phosphodiester linkages of RNA with positively charged guanidinium linkages provides the polycationic ribonucleic guanidine (RNG). RNG is designed to bind strongly to target DNA/RNA through the specific interactions of nucleobases and the attractive electrostatic interactions of backbones, thus RNG is a putative antisense/antigene agent. Preparation of uridine
用带正电的胍盐键代替RNA的带负电的磷酸二酯键,可提供聚阳离子核糖核酸胍(RNG)。RNG被设计为通过核碱基的特异性相互作用和主链的有吸引力的静电相互作用与目标DNA / RNA牢固结合,因此RNG是推定的反义/抗原试剂。报道了用于RNG合成的尿苷和腺嘌呤结构单元的制备以及低聚RNG的逐步合成。已合成了五聚体同型尿嘧啶基,腺苷酸和五聚体混合碱基序列。该方法还应用于方便的RNG固相合成。
