  Antimicrobial Activity of Peptidomimetics against Multidrug-Resistant Escherichia coli: A Comparative Study of Different Backbones

  摘要：

  Novel remedies in the battle against multidrug-resistant bacterial strains are urgently needed, and one obvious approach involves antimicrobial peptides and mimics hereof. The impact of alpha- and beta-peptoid as well as beta(3)-amino acid modifications on the activity profile against beta-lactamase-producing Escherichia coli was assessed by testing an array comprising different types of cationic peptidomimetics obtained by a general monomer-based solid-phase synthesis protocol. Most of the peptidomimetics possessed high to moderate activity toward multidrug-resistant E. coli as opposed to the corresponding inactive peptides. Nevertheless, differences in hemolytic activities indicate that a careful choice of backbone design constitutes a significant parameter in the search for effective cationic antimicrobial peptidomimetics targeting specific bacteria.

  肽/类肽杂合寡聚物：疏水性和相对侧链长度对抗菌活性和细胞选择性的影响

  摘要：

  先前对肽/拟肽杂交体的优化研究通常包括比较显示不同寡聚体长度和不同侧链的结构相关类似物。目前的工作涉及系统构建的一系列 16 个密切相关的 12 聚体低聚物，具有交替的阳离子/疏水设计，代表了广泛的疏水性和相对侧链长度的差异。目的是探索和合理化显示三个结构特征变化的低聚物亚类内的结构 - 活性关系：（i）阳离子侧链长度，（ii）疏水侧链长度，以及（iii）残基类型具有灵活的拟肽性质。阳离子残基侧链长度的增加导致疏水性降低，直到侧链变得比芳香族/疏水性侧链更长，此时疏水性略有增加。抗菌活性评估表明，具有最低疏水性的类似物对大肠杆菌的活性降低，而具有最短阳离子侧链的低聚物对铜绿假单胞菌最有效。因此，与铜绿假单胞菌的膜破坏相互作用似乎是由低聚物的疏水表面（由保护阳离子侧链的芳族基团组成）促进的。具有短阳离子侧链的肽模拟物表现出增加的溶血特性以及降低 HepG2（肝母细胞瘤 G2 细胞系）细胞活力。

  A particularly interesting class of oligomeric peptidomimetics is formed by the peptoids, which consist of N-substituted glycine residues. A solid-phase synthesis method for peptoids is presented in which these residues are introduced using their Fmoc derivatives. This "monomer" method allowed the monitored synthesis of relatively large quantities of pure peptoids as well as the translation of, in principle, any peptide into the corresponding peptoid. The required Fmoc-substituted glycines were accessible by convenient synthesis, and a number of monomers including those containing side chains with functional groups have been synthesized. The use of Fmoc monomers also allowed implementation of a solid-phase synthesis protocol on a commercial peptide synthesizer. The method was exemplified by the solid-phase syntheses of the (retro)peptoids of Leu-enkephalin and substance P. Mass spectrometric studies of (retro)peptoids were essential for their characterization, and the presence of the B- and Y "- type ions allows sequence analysis. Substance P (retro)-peptoids were biologically active. HPLC analysis showed an increased hydrophobicity, and pepsin treatment resulted in greatly reduced degradation compared with the corresponding peptide.

  We report the molecular design and synthesis of EG00229,2, the first small molecule ligand for the VEGF-A receptor neuropilin 1 (NRP1) and the structural characterization of NRP1-ligand complexes by NMR spectroscopy and X-ray crystallography. Mutagenesis Studies localized VEGF-A binding in the NRP1 b1 domain and it peptide Fragment of VEGF-A was shown to bind at the same site by NMR, providing the basis for small molecule design. Compound 2 demonstrated inhibition of VEGF-A binding to NRP1 and attenuated VEGFR2 phosphorylation in endothelial cells. Inhibition of migration of endothelial cells was also observed. The viability of A549 lung carcinoma cells wits reduced by 2, and it increased the potency of the cytotoxic agents paclitaxel and 5-fluorouracil when given in combination. These studies provide the basis for design of specific small molecule inhibitors of ligand binding to NRP1.
