The preparation of novel tris(macrocycle)s that transport Na+ through phospholipid bilayers is reported. All of the reported structures have the following structural elements: sidechain-macrocycle-spacer-macro-cycle-spacer-macrocycle-sidechain. The overall extension of the channel system is defined by the lengths of the spacer chains. The flexible sidearms are thought to be aligned with the lipid axis
据报道,新型Tris(大环)可通过磷脂双层转运Na +。所有报告的结构均具有以下结构元素:侧链-大环-间隔子-大环-循环-大环-侧链。通道系统的整体延伸范围由间隔链的长度决定。柔性侧臂被认为与脂质轴对齐并且与间隔链相反。在一定程度上,间隔链有助于结构的组织以及将含阳离子的孔与周围的脂质链隔离,更多的疏水链有望增强阳离子的运输。C 12 H 25 (CH 2)12 (CH2)12 Ç 12 ħ 25,1,用(C 12 H ^ 25)2 N(CH 2)2 (CH 2)12 (CH 2)12 (CH 2) 2N(C 12 H ^ 25)2,图11,示出了的Na +转运,着实增强。
