    • The invention discloses lipophilic oligonucleotide analogs that are capable of efficient passive diffusion across cell membranes. These oligonucleotides contain at least two nucleotide residues and have an octanol:water partition coefficient of about -0.3 to + 2.5 and a solubility in water of at least 0.001 νg/mL. Invention embodiments which include lipophilic oligonucleotide analogs having either at least 60 % of the internucleotide linkages are lipophilic, or at least 60 % of the bases contain lipophilic substitutions, or at least 60 % of the sugars contain lipophilic substitutions, or a combination of these sums to 60 %. These oligonucleotides may be conjugated to a label and used to visualize cells or subcellular compartments.
    • 本发明公开了能够跨细胞膜有效地被动扩散的亲脂寡核苷酸类似物。 这些寡核苷酸含有至少两个核苷酸残基并具有约-0.3至+2.5的辛醇:水分配系数和至少0.001ng / mL的在水中的溶解度。 包括具有至少60%核苷酸间连接的亲脂性寡核苷酸类似物的发明实施方式是亲脂性的,或至少60%的碱包含亲脂性取代,或至少60%的糖包含亲脂性取代,或这些和的组合 到60%。 这些寡核苷酸可以与标记偶联并用于使细胞或亚细胞区室可视化。
