description | Ions are transported across membrane mostly via carrier or channel mechanisms. Herein, a unique class of molecular‐machine‐inspired membrane transporters, termed molecular swings is reported that utilize a previously unexplored swing mechanism for promoting ion transport in a highly efficient manner. In particular, the molecular swing, which carries a 15‐crown‐5 unit as the ion‐binding and transporting unit, exhibits extremely high ion‐transport activities with EC50 values of 46 nm (a channel:lipid molar ratio of 1:4800 or 0.021 mol % relative to lipid) and 110 nm for K+ and Na+ ions, respectively. Remarkably, such ion transport activities remain high in a cholesterol‐rich environment, with EC50 values of 130 (0.045 mol % relative to lipid/cholesterol) and 326 nm for K+ and Na+ ions, respectively.
Ein molekulares Pendel „schwingt” Ionen effizient durch eine Lipidmembran mit EC50‐Werten von 46 nm (0.021 Mol‐% bezogen auf Lipid) und 110 nm für K+‐ bzw. Na+‐Ionen. K+‐Ionen werden 27 % schneller transportiert als durch Gramicidin A. Diese Strategie könnte zu verschiedenene Arten von Ionenkanälen mit potenziellen medizinischen Anwendungen führen. |
