标题:硫醇-二硫化物交换的结构-反应性关系
摘要:平衡常数由 36 个二硫醇和三硫醇与衍生自 2-巯基乙醇或二硫苏糖醇的二硫化物之间的硫醇-二硫化物交换确定.反应在甲醇-D/水性缓冲液 (Ph 7) 或甲醇中进行,在 25oc 下,使用 NMR 光谱跟踪反应.这些数据用于根据还原电位对二硫醇进行排序并推断其结构氧化时由它们形成的二硫化物.二硫醇的还原能力与氧化时形成的含二硫化物环的大小之间存在普遍的相关性:形成六元环的二硫醇还原性最强(k = 103-105 M 相对于氧化的 2-巯基乙醇);五元和七元环的还原性降低约 1 个数量级.类似于 1 的化合物,2-乙二硫醇在相对稀释的溶液 (-1 Mm) 中形成环状双(二硫化物)二聚体,但在较高浓度下聚合.其他类别的二硫醇在氧化时形成聚合物.

标题 :Synthesis of conducting polymers: polybutadienes from disubstituted butynes
发明人：THYAGARAJAN BUDALUR S

摘要:A two-step method is disclosed for chemically synthesizing substituted butadiene polymers from 1,4-disubstituted butynes. The first step in the synthesis of the butadiene polymer is the polymerization of 1,4-disubstituted butyne monomers. The substituted butyne polymer which results is then isomerized to the corresponding substituted butadiene polymer by subjecting the butyne to a weak organic base such as triethylamine. The isomerization reaction can be performed under very mild conditions and proceeds at ambient temperature.

摘要:Novel imidazolium [1,2a] pyridine (ImPr) based protic ionic liquids with thiolate/disulfide and different carboxylate anions have been synthesized and characterized by NMR, IR and Mass spectroscopy. Thermogravimetry analysis (TGA) has been done to investigate the thermal behavior of these protic ionic liquids. Their decomposition temperatures are determined in the range of 126-175°C except [ImPr][HSO4] which is most stable with decomposition temperature of 326°C. Differential Scanning Calorimetry (DSC) has been used to analyze phase behavior of these protic Ionic liquid. Glass transition temperature has been observed for all the synthesized PILs. Ionic conductivity of [Impr] [Pim] is measured at 25 °C, 58.6 µS/cm, which is a relatively good conductivity in comparison with imidazolium-based ionic liquids. All ionic liquids were synthesized using an environmentally friendly solvent free method.

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.

摘要:The subject invention pertains to the synthesis and characterization of V2O5/CdE NW/QD heterostructures. The V2O5/CdE heterostructures are versatile new materials constructs for light harvesting, charge separation, and the photocatalytic production of solar fuels; polymorphism of V2O5 and compositional alloying of both components provides for a substantial design space for tuning of interfacial energy offsets. Also provided are a new class of type-II heterostructures composed of cadmium chalcogenide QDs (CdE where E=S, Se, or Te) and α-V2O5 nanowires (NWs). The synthesis and characterization of V2O5/CdE NW/QD heterostructures, prepared via successive ionic layer adsorption and reaction (SILAR) and linker-assisted assembly (LAA), the characterization of their photoinduced charge-transfer reactivity using transient absorption spectroscopy, and their performance in the photocatalytic reduction of protons to hydrogen are also disclosed.
