Various new nucleosides bearing one or two lipophilic groups at the 2′-position have been synthesized. The lipophilic substituents were attached to a 2′-hydroxy, 2′-amino, or 2′-thio function. These lipophilic nucleosides anchor in large unilamellar POPC vesicles serving as phospholipid membrane models. The insertion of these molecules into the membranes was investigated by NMR techniques. For comparison
已经合成了各种在 2' 位带有一个或两个亲脂基团的新核苷。亲脂性取代基连接到 2'-羟基、2'-氨基或 2'-硫代官能团。这些亲脂性核苷锚定在用作磷脂膜模型的大型单层 POPC 囊泡中。通过核磁共振技术研究了这些分子插入到膜中的情况。为了进行比较,还研究了在 2'-、3'-或 5'-位置具有两个或三个亲脂基团的核苷。(© Wiley-VCH Verlag GmbH & Co. KGaA,69451 Weinheim,德国,2008 年)
