Tri(ethylene glycol) derived, low molecular-weight dendrons with various amine end groups were synthesized and characterized for their properties of binding and self-assembling with RNA using the Candida ribozyme as a model RNA molecule. These dendritic compounds form stable complexes and well-defined nanoscale particles with RNA molecules via electrostatic interactions and self-assembly process, while leaving the other terminal of the tri(ethylene glycol) chain accessible for targeting. This suggests that dendrimers of this type hold great promise for specific RNA targeting and RNA delivery.
使用念珠菌核酶作为模型 RNA 分子,合成了三(乙二醇)衍生的具有各种胺端基的低分子量树枝状分子,并表征了它们与 RNA 结合和自组装的特性。这些树枝状化合物通过静电相互作用和自组装过程与 RNA 分子形成稳定的复合物和明确的纳米级颗粒,同时使三(乙二醇)链的另一个末端易于靶向。这表明这种类型的树枝状聚合物对于特异性 RNA 靶向和 RNA 递送具有广阔的前景。
