  Comparing micellar, hemolytic, and antibacterial properties of di- and tricarboxyl dendritic amphiphiles

  摘要：

  Homologous dicarboxyl dendritic amphiphiles-RCONHC(CH(3))(CH(2)CH(2)COOH)(2), 4(n); and ROCO-NHC(CH(3))(CH(2)CH(2)COOH)(2), 5(n), where R = n-C(n)H(2n+1) and n = 13-22 carbon atoms-were synthesized. Critical micelle concentrations (CMCs) in aqueous triethanolamine solutions and at pH 7.4 were measured along with hemolytic activity (effective concentrations, EC(10)) in phosphate-buffered saline (PBS). Log CMC showed a linear dependence on chain length (n); the longest chain in each series had the lowest CMC-in triethanolamine: 4(21), 180 mu M and 5(22), 74 mu M and at pH 7.4: 4(21), 78 mu M and 5(22), 33 mu M. These two series, 4(n) and 5(n), and three series of homologous tricarboxyl dendritic amphiphiles-RCONHC(CH(2)CH(2)COOH)(3), 1(n); ROCONHC(CH(2)CH(2)COOH)(3), 2(n); RNHCONHC(CH(2)CH(2)COOH)(3), 3(n), where R = n-C(n)H(2n+1) and n = 13-22 carbon atoms-were tested for growth inhibition of Staphylococcus aureus strain ATCC 6358 and methicillin-resistant S. aureus (MRSA) strain ATCC 43330 by microdilution in 0.1-strength brain heart infusion broth (BHIB). Amphiphiles 4(19), 4(21), 5(18), and 5(20) showed the strongest antibacterial activity (2.2-3.4 mu g/mL) against S. aureus (vancomycin, MIC = 0.25 mu g/mL). These four plus 1(21), 2(20), 2(22), and 3(20) exhibited the strongest antibacterial activity (1.7-6.8 mu g/mL) against MRSA (vancomycin, MIC = 0.25 mu g/mL). The MICs of these amphiphiles against six clinical MRSA were similar to those against the ATCC strain. In PBS, EC(10)s of the most active homologues ranged from 7 to 18 mu g/mL and 18 to 220 mu g/mL for di- and tricarboxyl dendritic amphiphiles, respectively. To assess the potential safety of using dendritic amphiphiles as drugs, measurements of micellar and hemolytic properties were conducted in the same medium (full-strength BHIB) that was used for antibacterial activity. The CMCs (9-36 mu g/mL, similar to 18-72 mu M) of ten amphiphiles were measured by microdilution (log 2 progression) with dye-covered beads. The EC10s were similar to those in PBS. The MICs of most amphiphiles (14-72 mu g/mL) and vancomycin (1.1-2.2 mu g/mL) against both S. aureus and MRSA increased significantly compared to the MICs measured in 0.1-strength BHIB. The one exception, 5(18), had an MIC against S. aureus of 1.1 mu g/mL compared to vancomycin (2.2 mu g/mL). With CMC (9-18 mu g/mL) and EC10 (16 mu g/mL) values higher than the MIC, 5(18) was discovered as a lead for further development. (C) 2011 Elsevier Ltd. All rights reserved.

  通过 Tetrabis(2,2':6',2''-terpyridine)ruthenium(II) 配合物的电活性金属大分子：无外部抗衡离子的结构异构体和中性物种的树枝状纳米网络

  摘要：

  通过四个双(2,2':6',2''-三联吡啶)钌(II)连接的树枝状网络的概念被用来创建“树枝状甲烷”型金属大分子。此外，设计、合成和表征了两种结构异构的金属树枝状聚合物（16 和 17）。这两种异构体在光谱上相似，并显示出非常相似的物理和化学性质；然而，这些分子的内部密度和空隙区域是通过循环伏安法来区分的。描述了内部和外部树枝状分支的体积对三联吡啶-钌配合物的影响。类似的合成策略允许制备两代不具有外部抗衡离子的中性金属大分子（33 和 36）。描述了这些内部电荷平衡的中性物种的好处，

  Peptides derived from phage display typically show significantly weaker binding than their respective high affinity phage, which can bind to protein surfaces in a multivalent fashion. Here we show that mimicking key aspects of the multivalent architecture of the phage on an AB(5) dendritic wedge can enhance the affinity of a phage-display derived collagen binding peptide 100-fold (K(d) = 550 nM), allowing
