    • A method for the preparation of an antisense oligonucleotide or derivative thereof comprising the steps of: selecting a target nucleic acid, if necessary elucidating its sequence; generating the antisense oligonucleotide with the proviso that: the oligonucleotide comprises at least 8 residues; the oligonucleotide comprises at maximum twelve elements, which are capable of forming three hydrogen bonds each to cytosine bases; the oligonucleotide does not contain four or more consecutive elements, capable of forming three hydrogen bonds each with four consecutive cytosine bases (CCCC) within the target molecule or alternatively four or more consecutive elements of GGGG; the oligonucleotide does also not contain 2 or more series of three consecutive elements, capable of forming three hydrogen bonds each with three consecutive cytosine bases (CCC) within the target molecule, or alternatively 2 or more series of three consecutive elements of GGG; and the ratio between residues forming two hydrogen bonds per residue (2H-bond-R) with the target molecule and those residues forming three hydrogen bonds per residue (3H-bond-R) with the target molecule, is ruled by the following specifications: 3H-bond-R/3H-bond-R+2H-bond-R≧0.29; and synthesizing the oligonucleotide thus generated in a per se known manner.
    • 一种制备反义寡核苷酸或其衍生物的方法,包括以下步骤:如果需要,选择靶核酸阐明其序列; 产生反义寡核苷酸,条件是:寡核苷酸包含至少8个残基; 该寡核苷酸包含最多12个元件,其能够形成各自与胞嘧啶碱基的三个氢键; 寡核苷酸不含有四个或更多个连续的元件,能够在目标分子内形成三个氢键,每个具有四个连续的胞嘧啶碱基(CCCC),或者四个或更多个连续的GGGG元件; 寡核苷酸还不含有两个或更多个三个连续元件的系列,能够在目标分子内形成三个连接的胞嘧啶碱基(CCC)的三个氢键,或者另外两个或更多个三个连续的GGG元件系列; 并且与目标分子形成每个残基(2H-键-R)的两个氢键与每个残基形成三个氢键(3H-键-R)的残基与靶分子之间的比例由下列规格表示: 3H键-R / 3H键-R + 2H-键-R = 0.29; 并以本身已知的方式合成由此产生的寡核苷酸。
