A “click” ion channel platform has been established by employing a clickable guanosine azide or alkyne with covalent spacers. The resulting guanosine derivatives modulated the traffic of ions across the phospholipid bilayer, exhibiting a variation in conductance spanning three orders of magnitude (pS to nS).

通过使用带有共价间隔基的可点击的鸟苷叠氮化物或炔烃,已经建立了“点击”离子通道平台。所得的鸟苷衍生物调节了跨磷脂双层的离子流量,表现出跨三个数量级(pS至nS)的电导变化。丹磺酰基荧光团与膜结合荧光团尼罗红的Förster共振能量转移研究表明,丹磺酰基荧光团深深地嵌入在磷脂双层中。互补的胞嘧啶可以抑制磷脂双层中超分子鸟苷通道的传导。
