Methods and compositions are provided for forming complexes between dsDNA and novel oligomers comprising fused six-membered rings. By appropriate choice of target sequences and oligomers, complexes comprising oligomer-DNA are obtained with high association constants. The formation of complexes can be used for identification of specific dsDNA sequences, for inhibiting gene transcription, and as a therapeutic for inhibiting proliferation of undesired cells or modulation of expression of specific genes.
提供了一种形成双链DNA与含有融合六元环的新寡聚物之间复合物的方法和组合物。通过选择适当的靶序列和寡聚物,可以获得具有高结合常数的含寡聚物-DNA的复合物。复合物的形成可用于特定双链DNA序列的识别,用于抑制
基因转录,并作为抑制不需要的细胞增殖或调节特定
基因表达的治疗方法。
