  Total synthesis and structure–activity relationships of new echinocandin-like antifungal cyclolipohexapeptides

  摘要：

  A series of new echinocandin-like cyclolipohexapeptides were designed and total synthesized via solution phase [3 + 3]-segment coupling strategy with an attempt to improve antifungal activity. The designed compounds showed potent antifungal activities with broad spectrum. In particular, 11 compounds (i.e. 28a-e, 28g, 28i-j, 29a, 29c and 29e) showed better in vitro antifungal activities against Candida albicans or Aspergillus fumigatus than caspofungin. Moreover, the synthesized compounds provided new SAR information for the echinocandins. The findings in this work suggested that the "left" tripeptide segment of cyclolipohexapeptide scaffold might be a hydrophilic structural motif, whereas the "right" lipopeptide segment was preferred as a hydrophobic core. The amino acid component of the cyclolipohexapeptide scaffold could significantly affect the SAR of the side chains. (C) 2012 Elsevier Masson SAS. All rights reserved.

  The Synthesis and Property of Liquid Crystalline 4-Alkoxyl-4″-Cyano-p-Terphenyls

  摘要：

  The synthesis of some new 4-alkoxyl-4 "-cyano-p-terphenyls is described. The preliminary characterization by means of polarized optical microscopy, differential scanning calorimetry and X-ray diffraction shows that all these compounds are thermotropically liquid-crystalline and can form both the nematic and smectic mesophases.

• Synthesis and Mesomorphic Properties of Rigid-Core Ionic Liquid Crystals
  作者：Paul H. J. Kouwer、Timothy M. Swager

  DOI：10.1021/ja075651a

  日期：2007.11.1

  Ionic liquid crystals combine the unique solvent properties of ionic liquids with self-organization found for liquid crystals. We report a detailed analysis of the structure-property relationship of a series of new imidazolium-based liquid crystals with an extended aromatic core. Investigated parameters include length and nature of the tails, the length of the rigid core, the lateral substitution pattern, and the nature of the counterion. Depending on the molecular structure, two mesophases were observed: a bilayered SmA(2) phase and the more common monolayered SmA phase, both strongly interdigitated. Most materials show mesophases stable to high temperatures. For some cases, crystallization could be suppressed, and room-temperature liquid crystalline phases were obtained. The mesomorphic properties of several mixtures of ionic liquid crystals were investigated. Many mixtures showed full miscibility and ideal mixing behavior; however, in some instances we observed, surprisingly, complete demixing of the component SmA phases. The ionic liquid crystals and mixtures presented have potential applications, due to their low melting temperatures, wide temperature ranges, and stability with extra ion-doping.
