  A Europium Complex That Selectively Stains Nucleoli of Cells

  摘要：

  A europium complex selectively staining the nucleolus of NIH 3T3, HeLa, and HDF cells is reported. This complex possesses not only the advantage of the long lifetime of europium emission (0.3 ms), but also a chromophore that allows excitation at a relatively long wavelength (lambda(max) = 384 nm) and gives rise to an acceptable quantum yield (9%). The complex can be used both in live cell and fixed cell imaging, giving an average intracellular concentration on the order of 0.5 mu M. Strong binding to serum albumin has been demonstrated by examination of the analogous gadolinium complex, studying relaxivity changes with increasing protein concentration. The intracellular speciation of the complex has been examined by circularly polarized emission spectroscopy and is consistent with the presence of more than one europium species, possibly protein bound.

High overall emission quantum yields in aqueous media are attenuated in the presence of protein or certain oxy anions due to displacement of the N,N′‐chelated sensitiser. Nevertheless, these complexes are

  Imidazolium salts can be classed as surfactants, detergents, ionic liquids, reagents, catalysts or solvents. A study of the toxicity and ecotoxicity of these salts yields valuable information for their use as pharmaceuticals as well as impact on the environment. Our approach to screen a series of chiral imidazolium salts for toxicity to bacteria and fungi, including clinical pathogen strains, has led to the identification of a ‘hit’ MRSA selective antimicrobial compound. Preliminary structure–activity-relationship (SAR) information (required position of L-phenylalanine and L-valine group) is also elucidated within this first generation of compounds. Conversely, most of the imidazolium salts were nontoxic (IC95 > 2 mM) to the 12 fungi strains and 8 bacteria strains screened, and we propose that they are suitable candidates for ‘green chemistry’ applications. Ecotoxicity studies (Biodegradation ISO 14593 ‘CO2 Headspace Test’) of two bromide ionic liquids containing L-phenylalanine residues indicate that these ionic liquids passed the test (>60% in 28 days) and classed as readily biodegradable.

  咪唑盐可分类为表面活性剂、洗涤剂、离子液体、试剂、催化剂或溶剂。对这些盐的毒性和生态毒性的研究，为其作为药物的使用以及对环境的影响提供了宝贵的信息。我们对一系列手性咪唑盐对细菌和真菌的毒性进行了筛选，包括临床病原菌株，从而鉴定出一种针对MRSA的选择性抗菌化合物。初步的结构-活性关系（SAR）信息（L-苯丙氨酸和L-缬氨酸集团所需的定位）也在这一代化合物中得以阐明。相反，大多数咪唑盐对筛选的12种真菌株和8种细菌株无毒（IC95 > 2 mM），我们提出它们是适合“绿色化学”应用的候选物质。生态毒性研究（ISO 14593生物降解“CO2顶空测试”）表明，含有L-苯丙氨酸残基的两种溴离子液体通过了测试（28天内>60%），被归类为易于生物降解。

The glycine derivative is a good gelator of chloroform, the alanine derivative gels ethanol and toluene, and the phenylalanine derivative gels benzene and toluene. The tryptophan derivative does not gel any of the solvents tested, most probably due to its more bulky structure, but forms microspheres by evaporation-induced

  已经用甘氨酸，L-丙氨酸，L-苯丙氨酸和L-色氨酸乙酯侧链制备了四个新颖的​​氨基酸官能化的亚苯基。甘氨酸衍生物是氯仿的良好胶凝剂，丙氨酸衍生物使乙醇和甲苯胶凝，苯丙氨酸衍生物使苯和甲苯胶凝。色氨酸衍生物不会胶凝任何测试的溶剂，这很可能是由于其更大的结构，而是通过蒸发诱导的自组装形成微球。使用红外，紫外吸收和荧光光谱，浓度和温度相关的NMR，以及在干燥的干凝胶和湿有机凝胶上进行X射线散射实验，研究了π胶凝剂的自组装特性。后面的实验表明，氯仿中的甘氨酸凝胶包括柱状聚集体，整体呈无序的柱状斜中间相。这些化合物之所以引起人们的关注是因为三苯撑液晶具有众所周知的空穴传输特性：这些化合物的1-D柱状组件可以在有机电子设备中找到应用。

  我们首次报告了对合成（由绿色化学指标支持），聚集性质，细菌/真菌毒性以及一系列24 L-苯丙氨酸衍生的表面活性离子液体（SAILs）的生物降解作用的初步数据的综合研究。各种阳离子头基包括吡啶鎓，咪唑鎓和胆鎓基团，能够全面分析烷基酯链的作用（从C 2到C 16）关于新型SAILs的合成，毒性，生物降解性和表面活性剂性能的研究。对SAIL的评估表明，各种特性严格取决于侧链长度，包括它们的细菌和真菌毒性（从低毒性到高毒性）以及聚集特性。L的加法将亲脂性侧链连接至阳离子头基的-苯基丙氨酸部分导致苯基基团基本上有助于自组装性能。与其他表面活性剂相比，苯环的分散相互作用和侧链疏水性之间的相互作用使我们能够对新型SAIL（从而鉴定出显着的SAIL）进行排名。这项研究中报道的SAILs的CMC值比具有相同侧链长度的常规表面活性剂报告的CMC值显着降低（最多10倍）。吸附和胶束化是影响所研究的SAILs毒性
