    摘要:
    本工作的目的是设计功能化的脂膜,该脂膜可以在界面处与镧系元素离子选择性相互作用,并利用由这种分子识别过程诱导的膜之间的相互作用,以建立自组装囊泡或控制渗透性。膜上的镧系离子。合成带有β-二酮单元作为头部基团的两亲分子,并将其掺入磷脂囊泡中。Eu(III)离子与两亲性配体的结合可导致形成一个复合物,该复合物涉及同一囊泡膜(囊内复合物)或两个不同囊泡(囊泡间复合物)的配体。通过荧光分析,光散射和电子显微镜等辅助技术研究了Eu(III)离子对囊泡行为的影响。证明了囊内发光的Eu /β-二酮配体(1/2)配合物的形成。随着膜中配体浓度的增加,结合常数线性增加,揭示了配体在囊泡膜中分布的协同作用。可以利用该复合物的发光来监测在囊泡界面处的复合动力学,以及跨膜的离子传输。通过封装2,6-二吡啶甲酸(DPA)作为竞争配体,形成发光的Eu / DPA复合物,可以追踪离子在膜上的传输动力学。这些功能性囊泡被

    Anion-Selective Cholesterol Decorated Macrocyclic Transmembrane Ion Carriers
    摘要:
    Anion transporters play a vital role in cellular processes and their dysregulation leads to a range of diseases such as cystic fibrosis, Bartters syndrome and epilepsy. Synthetic chloride transporters are known to induce apoptosis in cancer cell lines. Herein, we report triamide macrocycles that are easily synthesized and externally functionalized by pendant membrane-permeable groups. Among a variety of chains appended onto the macrocycle scaffold, cholesterol is found to be the best with an EC50 value of 0.44 mu M. The macrocycle is highly anion-selective and transports ions via an OH-/X- antiport mechanism. The macrocycle is an interesting scaffold for ion-transport as it is able to discriminate between various anions and shows a preference for SCN- and Cl-. Such anion-selective transporters are highly attractive model systems to study ion-transport mechanisms and could potentially be of high therapeutic value.
