    Abstract: Oligonucleotide analogs (I) and their physiologically tolerable salts. Oligonucleotide analogs and their physiologically tolerable salts of formula (I) are new. R = H, a substituent or -P(=W)ZZ'; R = H, OH, 1-18C alkoxy, halo, azido or amino; B = nucleotide base residue; A = oxy or methylene; d, e, f = 0-50; i = 1-10; r = 0 or 1; W = oxo, selenoxo or thioxo; V = oxy, sulfandiyl or imino; Y = oxy, sulfandiyl, imino or methylene; Y' = oxy, sulfandiyl, imino, (CH2)m or V(CH2)m; m = 1-18; X = OH or SH; U, R , R = substituents; p = 1-100; q = 0-18; R = H or functional group; Sp = a (3',5'-) spacer group of formula (i); g, g' = 0 or 1; h = 0-10; G = 1-12C alkylene (optionally substituted), (6-14C)aryldi-(1-8C)alkylene, 6-18C arylene, (CH2CH2V) alpha CH2CH2, (CH2V) alpha CH2, -(G-Y-P(=W)(U)-Y'-) beta or a group of formula (ii); alpha = 1-11; beta = 1-6; Z, Z' = OH, (seleno)thio or a substituent; provided that r is 0 when V is Y' and is 1 if i is greater than 1. Positions of R and the adjacent phosphoryl residue can be reversed; each nucleoside had D- or L-configuration and each B has alpha or beta configuration. Independent claims are also included for: (1) a method for producing (I); (2) the phosphitylation reagent of formula DMTr-X'-G'-Y''-P(U')(NR R ); and (3) a pharmaceutical composition containing at least one compound (I) and optionally auxiliary, carrier and/or other active agents. R , R = 1-12C alkyl or together form a 5-6 membered ring; DMTr = dimethoxytrityl; X', Y'' = oxy or sulfandiyl; U' = 1-4C alkyl or protected OH; G' = (CH2CH2O) alpha CH2CH2 or CH2CH(OR')CH2; and R' = 1-18C alkyl, 6-14C aryl or 6-14C aryl(1-8C) alkyl.

    Abstract: The invention relates to compounds of the formula I in which R is H, alkyl, acyl, aryl or a phosphate residue; R is H, OH, alkoxy, NH2 or halogen; B is a base customary in nucleotide chemistry; a is O or CH2; n is an integer from 1 to 100; W is O, S or Se; V is O, S or NH; Y is O, S, NH or CH2; Y' is O, S, NH or alkylene; X is OH or SH; U is OH, SH, SeH, alkyl, aryl or amine, and Z is OH, SH, SeH, an optionally substituted radical from the series comprising alkyl, aryl, heteroaryl, alkoxy or amino or a group which favours intracellular uptake or as labelling of a DNA probe or which on hybridisation interacts with the target nucleic acid, where if Z is OH, SH, CH3 or OC2H5, at least one of the groups X, Y, Y', V, W is not equal to OH or O, or R is not equal to H; process for their preparation and their use as inhibitors of gene expression, as probes for detecting nucleic acids and as aids in molecular biology.
