  摘要：

  通过使用CO 2气球（1个大气压），在温和的条件下，制备了一系列具有季鎓中心和氢键键合给体基团的双功能相转移催化剂，用于将CO 2与市售环氧化物固定。在2.5摩尔％的非手性双官能相转移催化剂的存在下，以良好至优异的产率（高达95％）获得环状碳酸酯。另外，通过用1mol％的具有低对映选择性的手性双官能相转移催化剂对外消旋环氧化物进行动力学拆分，获得了光学碳酸盐和环氧化物。这些催化剂具有简单的合成路线，良好的模块性和高效率。

  Thiazole orange – Spermine conjugate: A potent human telomerase inhibitor comparable to BRACO-19

  摘要：

  In this report, we synthesized a series of TO conjugates containing different amino side chains and investigated their binding to telomeric G-quadruplex DNA (G4) using several biophysical methods including fluorometric titration and thermal denaturation monitored by fluorescence and circular dichroism. The composition of side chains strongly affects the binding of these molecules to G-quadruplex DNA. Incorporation of amino side chains increases the binding affinity of TO toward G4 but has a minimal effect on its selectivity for G4 over duplex DNA. The plausible binding modes are a synergistic effect of end-stacking and groove interactions as indicated by docking studies. Inhibition of human telomerase activity by TO derivatives was determined in vitro by the TRAP assay. Several derivatives can selectively inhibit the activity of telomerase over DNA polymerase at low concentrations. More significantly, TO-spermine conjugate (16) exhibits a remarkable effect on telomerase inhibition in the submicromolar range, which is comparable to the inhibition effect of a well-known G4 ligand, BRACO-19. Our results here provide guidance of utilizing TO derivatives as a viable scaffold to design novel G4 ligands, G4 probes, and potent telomerase inhibitors. (C) 2019 Elsevier Masson SAS.

  A C-terminus modification to a binding pocket-modified vancomycin introduces a quaternary ammonium salt that provides a binding pocket-modified vancomycin analog with a second mechanism of action that is independent of D-Ala-D-Ala/D-Ala-D-Lac binding. The modification disrupts cell wall integrity and induces cell wall permeability complementary to the glycopeptide inhibition of cell wall synthesis, and provides synergistic improvements in antimicrobial potency (200-fold) against vancomycin-resistant bacteria. Combining the C- terminus and binding pocket modifications with an orthogonal (4-chlorobiphenyl ) methyl addition to the vancomycin disaccharide provides even more potent antimicrobial agents whose activity can be attributed to three independent and synergistic mechanisms of action, only one of which requires D-Ala-D-Ala/D-Ala- D-Lac binding. The resulting modified vancomycins display little propensity for acquired resistance through serial exposure of vancomycin-resistant Enterococci and their durability against such challenges as well as their antimicrobial potency follow predicable trends. Methods of treatment with and compositions containing the modified vancomycins are disclosed.
