GRAPHICAL ABSTRACT ABSTRACT Crown ethers possessing an external chain are called lariatethers. Huisgen cycloaddition is the 1,3-dipolar cycloaddition occurs between a suitable azide and terminal alkyne to give a stable 1,2,3-triazole system. It is the most common reaction of the so called philosophy of “click chemistry,” introduced by Nobel prize laureate Sharpless.

significantly enhances the thermal stability of HIVTARRNA and interacts stoichiometrically with HIVTARRNA with a low nanomolar affinity. 5 displayed enhanced binding compared to its individual building blocks including the neomycin dimer azide and benzimidazole alkyne. In essence, a high affinity multivalent ligand was designed and synthesized to targetHIVTARRNA.
通过高亲和力结合小分子识别RNA对于扩大现有的RNA识别方法以及开发新型RNA结合药物至关重要。新型新霉素二聚体苯并咪唑共轭物5(DPA 83)的合成是通过将新霉素二聚体与苯并咪唑炔烃偶联,并使用点击化学方法靶向HIV TAR RNA上的多个结合位点。配体5显着增强了HIV TAR RNA的热稳定性,并与化学计量学上相互作用的HIV TAR RNA具有较低的纳摩尔摩尔亲和力。与包括新霉素二聚体叠氮化物和苯并咪唑炔烃在内的各个组成部分相比,图5所示的结合增强。本质上,设计并合成了靶向HIV TAR RNA的高亲和力多价配体。
Reverse micelle-based water-soluble nanoparticles for simultaneous bioimaging and drug delivery
ACW-NPs was confirmed by both the Förster resonance energy transfer (FRET) between 5-((2-aminoethyl)amino)naphthalene-1-sulfonic acid (1,5-EDANS) and benzoic acid, 4-[2-[4-(dimethylamino)phenyl]diazenyl] (DABCYL) and satisfactory colloidal stability in 10% fetal bovine serum. Importantly, featured by the gentle synthetic strategy, confined water pool, and carboxylic acid-functionalized surface, the new
The controlled secondary self‐assembly of amphiphilic molecules in solution is theoretically and practically significant in amphiphilic molecular applications. An amphiphilic β‐cyclodextrin (β‐CD) dimer, namely LA‐(CD)2, has been synthesized, wherein one lithocholic acid (LA) unit is hydrophobic and two β‐CD units are hydrophilic. In an aqueous solution at room temperature, LA‐(CD)2 self‐assembles
在两亲性分子应用中,两亲分子在溶液中的受控次级自组装在理论上和实践上都很重要。已经合成了两亲性的β-环糊精(β-CD)二聚体,即LA-(CD)2,其中一个锂盐酸(LA)单元是疏水的,而两个β-CD单元是亲水的。在室温下,LA‐(CD)2在水溶液中会自组装成球形胶束,而无需超声处理。初级胶束在超声作用下解离,然后形成具有分支结构的自组装体。在高温下,支链聚集体还原为初级胶束。超声驱动的二次自组装通过透射电子显微镜,动态光散射,1证实。1 H NMR光谱学和Cu 2+反应实验。此外,二维NOESY NMR和UV / Vis光谱结果表明,初级胶束的形成是由亲水-疏水相互作用驱动的,而主体-客体的相互作用则促进了次级组装的形成。此外,超声波在室温下可有效破坏主要的亲水-疏水平衡,同时增强LA和β-CD部分之间的宿主-客体相互作用。
