  A conceptually new class of cationic amphiphiles, Sunfish amphiphiles, designed for the delivery of genes into cells is introduced. Sunfish amphiphiles have two hydrophobic tails, connected at the 4- and the N-position to the cationic pyridinium headgroup. Two extreme morphologies visualised by backfolding and combining of both tails at one site (matching situation) or unfolding of the tails at distinct

  引入了一种概念上新的阳离子两亲物，Sunfish 两亲物，其设计用于将基因传递到细胞中。翻车鱼两亲分子有两个疏水尾部，在 4 位和 N 位连接到阳离子吡啶鎓头基团。通过在一个位点（匹配情况）或在生物膜的不同相互作用位点展开尾部的回折和组合来可视化的两种极端形态将导致形态行为的显着差异。基本原理允许通过使用 Sunfish/辅助脂质/DNA 复合物 (lipoplex) 的这种形态学改变来控制释放。通常出色的转染效率可能与这些形态变化有关。此外，太阳鱼两亲物具有低毒性，导致内化后细胞存活率高。详细讨论了基本原理、设计、合成和体外转染潜力。此外，还研究了太阳鱼两亲物的一些理化特性。(C) Wiley-VCH Verlag GmbH & Co.
