标题:双(ami胺肟)的合成及其作为铀酰络合剂的性能评估
摘要:铀污染涉及高毒性和放射性,因此对人类健康和环境构成严重威胁.螯合是螯合铀的有效方法.众所周知,基于肟基的螯合剂能够有效地络合铀酰阳离子.为此,通过羟胺与相应的二腈反应合成了各种双(ami胺肟).在这些化合物中,A胺肟被各种长度的链隔开,有些长度包括杂环(吡啶或1,3,5-三嗪).通过等温滴定热量法(itc)测定它们的亲和常数和热力学参数,评估了这些双(ami胺肟)在水中复合铀酰阳离子的能力.还进行了dft计算,确定在铀酰阳离子和肟酸基团之间形成的配合物的最佳结构.在这项工作中也合成的四(ami胺肟)对铀显示出非常好的亲和力,并且一个分子能够螯合几个铀酰阳离子.这些结果对铀污染废水的修复具有重要意义,并为设计和合成新型a胺肟化合物开辟了一些前景.

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:Described are DNA sequencing systems and methods. Systems and methods for determining the nucleotide sequence of a polynucleotide may include determining the sequence of a polynucleotide with more than four types of bases by increasing the number of encoding states in sequencing by synthesis (SBS) systems. The systems and methods may expand the encoding space of current systems by discretizing the amplitude space in a channel into more than two states, and/or by adding additional channels.

摘要:The application relates to DNA sequencing systems and methods. Systems and methods for determining the nucleotide sequence of a polynucleotide may include introducing a fourth labelled nucleotide in a two-channel sequencing by synthesis system to create alternative X-Y scatterplot shapes where the x-axis represents the intensity of fluorescence at one wavelength (channel 1), and the y-axis represents intensity of fluorescence at another wavelength (channel 2 The alternative scatterplot shapes may allow for additional encoding space for empty well detection.
