A highly efficient and perfectly reversible ionicgate that can be activated by pH or UV light is demonstrated. Switching between the OFF state and the ON state is mainly dependent on the surface charge transition brought about by a malachitegreen derivative attached to the interior surface of an ion track‐etched conical nanochannel, which makes it suitable for confined spaces.

site. Herein, we describe the design, synthesis, and biological evaluation of a focused library of novel steroid-derived analogues targeting the bimetallic catalytic site, representing an entirely unique class of ATX inhibitors of type V designation, which demonstrate significant pathway-relevant biochemical and phenotypic biological effects. The current compounds modulated LPA-mediated ATX allostery
Autotaxin (ATX) 促进溶血磷脂酰胆碱水解为溶血磷脂酸 (LPA),这是一种生物活性磷脂,可促进多种组织类型中的多种细胞作用。LPA表达异常可导致癌症和纤维化等疾病的进展。以前,我们发现了一种有效的 ATX 类固醇衍生的混合(部分正构和变构)抑制剂,它不会与催化位点形成相互作用。在这里,我们描述了针对双金属催化位点的新型类固醇衍生类似物的集中库的设计、合成和生物学评估,代表了一类完全独特的 V 型 ATX 抑制剂,证明了与通路相关的显着生化和表型生物学效应。1内化,与观察到的下游信号级联和趋化性诱导的减少一致。这些新型 V 型 ATX 抑制剂代表了一种有前途的工具来灭活 ATX-LPA 信号轴。
Photo‐Powered Collapse of Supramolecular Polymers Based on an Overcrowded Alkene Switch
A supramolecularpolymer was constructed from a light-driven overcrowdedalkeneswitch modified with two alkylated gallic acid amide pendants (MSP-1). Upon UV irradiation, stable MSP-1 isomerized into unstable MSP-2, which induced the effective collapse of well-defined cross-linked supramolecularpolymers, and the reassembly can be realized by aging at low temperature.
