摘要:一种新型荧光传感器1,通过引入二氯荧光素基团作为荧光报告单元和两个氮杂冠醚大环作为结合位点进行功能化设计,合成和表征.研究发现,传感器1在dmso-H2O(1:1,V/v)中能选择性地识别cu2+,表现为显著的荧光淬灭,这归因于1与cu2+之间的1:2络合物形成,而其他离子如k+,Na+,Mg2+,Zn2+,Ba2+,Co2+,Ca2+,Fe2+,Fe3+,Pb2+,Ni2+和ag+则导致无或极小的荧光变化.此外,传感器1对cu2+表现出快速,稳定且线性的响应,浓度范围从5 x 10-7至1 x 10-5 Mol L-1,检测限低至8.7 x 10-8 Mol L-1.进一步地,传感器1被应用于实际水样中cu2+的测定,结果令人满意.

摘要:A method for a synthesis of a polymer containing multiple epoxy groups includes steps of: under protection of nitrogen or argon, with a photosensitive free radical initiator under an ultraviolet light irradiation, initiating a mixture of a dithiol compound and alkynyl glycidyl ether or other alkynyl-containing compounds to proceed a thiol-yne polymerization, so as to obtain the polymer. The number of the epoxy groups is able to be adjusted through changing a type of a dithiol monomer, a mixing ratio of the dithiol monomer, and a mixing ratio between the alkynyl glycidyl ether and other alkynyl compounds. The present invention has advantages of: fast reaction, convenient process, easy post-processing, a large number of the epoxy groups, and adjustable and controllable content. The obtained polymer has a wide potential application in fields of coating, adhesive, ink, encapsulating material, resin for composite material, additive, high performance material, function material, and so on.

摘要:The 2-(4-tolylsulfonyl)ethoxymethyl (TEM) as a new 2'-OH protecting group is reported for the RNA synthesis on the solid support using the phosphoramidite chemistry. The usefulness of the 2'-0-TEM group is exemplified by the synthesis of 12 different oligo-RNAs of various sizes (14-38nt long). The stepwise coupling yield varied from 97 - 99 % with an optimized coupling time of 120s. Synthesis of all four pure phosphoramidite building blocks are also described. Two new reliable parameters, δc2' - δc3s and δn2' - δH3' have been suggested for the characterization of isomeric 2'-0-TEM and 3'-0-TEM as well as other isomeric mono 273 '-protected ribonucleoside derivatives. The most striking feature of this strategy is that the crude RNA prepared using our 2'-0-TEM strategy is sufficiently pure (>90 %) for molecular biology research without any additional purification step, thereby making oligo-RNAs easily available at a relatively low cost, saving both time and lab resources.

权利人:FRANKLIN AND MARSHALL COLLEGE
摘要:This invention relates to a process for the phase-controlled synthesis of ternary and quaternary mixed-metal sulfide nanoparticles by reacting soft metal ions with hard metal ions in a high-boiling organic solvent in the presence of a complexing and activating ligands to control the reactivity of the metal ions. Ternary and quaternary mixed metal sulfides nanoparticles of copper, sulfur, and iron, aluminum, tin, and silicon are preferred. This invention also relates to the phase controlled preparation of polymorphs of bornite nanoparticles and the phase controlled preparation of stabilized α- and γ-chalconite nanoparticles.

摘要:This invention relates to novel multibinding compounds (agents) that are antibacterial agents. The multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands in their monovalent (i.e., unlinked) state have the ability to bind to a an enzyme involved in cell wall biosynthesis and metabolism, a precursor used in the synthesis of the bacterial cell wall and/or the bacterial cell surface thereby interfere with the synthesis and/or metabolism of the cell wall. In particular the multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands hasn a ligand domain capable of binding to penicillin binding proteins, a transpeptidase enzyme, a substrate of a transpeptidase enzyme, a beta-lactamase enzyme, pencillinase enzyme, cephalosporinase enzyme, a transglycoslase enzyme, or a transglycosylase enzyme substrate; Preferably, the ligands are selected from the beta lactam or glycopeptide class of antibacterial agents.
