A polymer composition is disclosed composed of morpholino subunit structures linked together by uncharged, phosphorus-containing chiral linkages, one to three atoms in length. These chiral linkages join the morpholino nitrogen of one subunit to the 5' exocyclic carbon of an adjacent subunit. Each subunit contains a purine or pyrimidine base-pairing moiety effective to bind by hydrogen bonding to a specific base or base-pair in a target polynucleotide.
本发明公开了一种聚合物组合物,它由吗啉亚基结构组成,这些结构通过长度为一至三个原子的不带电的含
磷手性连接物连接在一起。这些手性连接将一个亚基的吗啉基氮与相邻亚基的 5'外环碳连接起来。每个亚基都含有一个
嘌呤或
嘧啶碱基配对分子,可通过氢键与目标多核苷酸中的特定碱基或碱基对结合。
