Oligonucleotides having the general formula, ##STR1## in which B denotes an arbitrary nucleobase, A equals 0 or CH.sub.2 ; X or Z equals O, S, NH or denotes CH.sub.2 whereby X and Z can be the same or different, V and W denote O, S, Se, NH.sub.2 or an alkyloxy residue, or OH or SH whereby V and W can be the same or different in a monomer unit and L is a H atom or a partner of a binding pair and C equals --O--R and R is an alkyl group with at least 1 C atom which may be modified if desired, or it denotes an alkenyl or alkynyl group with at least 2 C atoms which may be modified if desired, whereby the modification consists of a substitution by one or several halogen, cyano, carboxy, hydroxy, nitro or/and mercapto residues, and n is an arbitrary whole number, are stable antisense probes which bind specifically. Such oligonucleotides and polynucleotides may be used for the regulation of gene expression and as pharmaceutical agents. They are synthesized from the corresponding 2'-substituted monomers according to well-known methods, preferably on a solid phase.
具有一般式##STR1##的寡核苷酸,其中B表示任意核碱基,A等于0或CH.sub.2;X或Z等于O,S,NH或表示CH.sub.2,其中X和Z可以相同或不同,V和W表示O,S,Se,NH.sub.2或烷氧基,或OH或SH,其中V和W可以在单体单元中相同或不同,L是H原子或配对物的伴侣,C等于--O--R,R是至少具有1个C原子的烷基,如果需要,可以进行修饰,或者它表示至少具有2个C原子的烯烃或炔烃基团,如果需要,可以进行修饰,其中修饰包括用一个或多个卤素,氰基,羧基,羟基,硝基和/或巯基取代,n是任意整数,是稳定的特异性抗义探针。这些寡核苷酸和多核苷酸可用于调节基因表达和作为药物。它们是从相应的2'-取代单体按照众所周知的方法合成的,优选在固相上合成。
