    • The invention relates to compounds of the formula I ##STR1## where R.sup.1 is H, alkyl, acyl, aryl, or a phosphate residue; R.sup.2 is H, OH, alkoxy, NH.sub.2, or halogen; B is a base customary in nucleotide chemistry; a is O or CH.sub.2 ; n is an integer from 1 to 100; W=O, S or Se; V=O, S, or NH; Y=O, S, NH, or CH.sub.2 ; Y'=O, S, NH, or alkylene; X=OH or SH; U=OH, SH, SeH, alkyl, alkoxy, aryl, aryloxy, or amine, and Z=OH, SH, SeH, an optionally substituted radical from the group comprising alkyl, aryl, heteroaryl, alkoxy, or amino, or a group which favors intracellular uptake or serves as the label of a DNA probe or attacks the target nucleic acid during hybridization, where if Z=OH, SH, CH.sub.3, or OC.sub.2 H.sub.5, at least one of the groups X, Y, Y', V, or W is not OH or O or R.sup.1 is not H; a process for their preparation and their use as inhibitors of gene expression, as probes for detecting nucleic acids and as aids in molecular biology.
    • 本发明涉及式Ⅰ化合物,其中R1是H,烷基,酰基,芳基或磷酸酯残基; R2是H,OH,烷氧基,NH2或卤素; B是核苷酸化学中常规的基础; a是O或CH2; n为1〜100的整数, W = O,S或Se; V = O,S或NH; Y = O,S,NH或CH 2; Y'= O,S,NH或亚烷基; X = OH或SH; U = OH,SH,SeH,烷基,烷氧基,芳基,芳氧基或胺,Z = OH,SH,SeH,任选取代的基团,其包含烷基,芳基,杂芳基,烷氧基或氨基, 其有利于细胞内吸收或用作DNA探针的标记或在杂交期间攻击靶核酸,其中如果Z = OH,SH,CH 3或OC 2 H 5,X,Y,Y',V, 或W不是OH或O或R 1不是H; 其制备方法及其作为基因表达抑制剂的用途,作为检测核酸的探针和分子生物学的辅助工具。
