  Self-Association of Protected Newkome-Type Second-Generation Dendrimers at Nanomolar Level Concentrations in Aqueous Solution

  摘要：

  Protected Newkome-type second-generation dendrimers (based on Lin's amine) were synthesized with a pyrene moiety attached to the core. The photophysical property in aqueous solution of the protected dendrimers shows self-association behavior in water. Pyrene excimer emission at 475 nm is observed in water even at very low concentrations of protected dendrimer (ca. 5 x 10(-8) M). This emission band is absent in other solvents even up to a concentration of 10(-5) M. The corresponding unprotected dendrimer does not show the pyrene excimer fluorescence. The amide of pyrene butyric acid with tert-butylamine shows the formation of excimer, albeit with very low intensity. Quenching studies on the dendrimer with hydrophilic quencher iodide anion (I-) reveal that there is significant quenching of fluorescence intensity in the case of N-tert-butyl-4-pyren-1-ylbutyramide as compared to that of the pyrene-attached second-generation protected dendrimer. This shows that the pyrene moiety in the case of the protected dendrimer is significantly shielded from the surrounding.

  Dendritic side chains have been used to modify the binding environment in anthracene‐based synthetic carbohydrate receptors. Control of length, charge, and branching enabled the positioning of side‐chain carboxylate groups in such a way that they assisted in binding substrates rather than blocking the cavity. Conformational degeneracy in the dendrimers resulted in effective preorganization despite

  树突侧链已被用来修饰基于蒽的合成碳水化合物受体的结合环境。长度、电荷和支化的控制使得侧链羧酸酯基团的定位能够帮助结合底物而不是阻塞空腔。尽管系统具有灵活性，但树枝状聚合物的构象简并性导致了有效的预组织。观察到与水中的葡萄糖铵离子的强结合，K a 值高达7000  M -1。尽管存在溶剂竞争且不存在静电相互作用，但对不带电底物（葡萄糖和N-乙酰氨基葡萄糖）的亲和力也得到增强。

  The present invention is directed to the bifunctional compounds and the use of such bifunctional compounds to lower plasma levels of extracellular target molecules by lysosomal degradation. Such bifunctional compounds have a cell surface receptor ligand covalently linked to a ligand that is capable of binding to an extracellular target molecule (such as a ligand for a growth factor, a cytokine, a chemokine, a hormone, a neurotransmitter, a capsid, a soluble receptor, an extracellular secreted protein, an antibody, a lipoprotein, an exosome, a virus, a cell, or a plasma membrane protein), where the cell surface receptor is associated with receptor mediated endocytosis, including asialoglycoprotein receptor (ASGPR) mediated lysosomal degradation and mannose-6-phosphate (M6PR) mediated lysosomal degradation. Pharmaceutical compositions comprising such bifunctional compounds and methods of treating a disease or disorder mediated by an extracellular molecule using such bifunctional compounds are also provided herein.

  Tri-nitrilotriacetic acid (NTA)-based fluorescent probes were developed and used to image His-tagged-labelled outer membrane protein C (His-OmpC) in live Escherichia coli. One of these probes was designed to light up upon binding, which provided the means to assess changes in the His-OmpC expression levels by taking a simple fluorescence spectrum.
