  Analogs of platelet activating factor. 7. Bis-aryl amide and bis-aryl urea receptor antagonists of PAF

  摘要：

  A series of bis-aryl amide (13-57 and 66-81) and bis-aryl urea (58 and 85) antagonists of platelet-activating factor (PAF) was prepared that contain, separating the two aromatic rings, linear amide linkages of the form -(CH2)nCONH- (n = 0-2), -OCH2CONH-, and -(CH2)nNHCO- (n = 0-1), branched amide linkages of the form -(CH2)nN(COR)- (n = 1-3, R = CH3 or n-C3H7), and -N(COCH3)CH2-, and urea linkages of the form -NHCONH- and -CH2N(CONHCH3)-. These compounds were examined for their ability to inhibit PAF-induced platelet aggregation of rabbit platelets. These in vitro data were compared to similar data obtained for a number of known PAF antagonists. The compounds were evaluated in vivo, in the mouse, for their ability to prevent death induced by a lethal challenge of PAF. The relationships between the biological activity and the nature, lipophilicity, and position of substituents of the aromatic rings were studied. Best activity was observed for compounds having linkages of the type -CH2CONH-, -CH2N(COR)-, and -CH2NHCO-. Many of these compounds inhibit PAF-induced platelet aggregation with IC50's under 1 muM.

  摘要：

  摘要 在本文中，我们希望报告基于查尔酮酯的同源系列化合物的液晶性质，这些化合物在正烷氧基中具有脂肪族链长（n = 1 至 10、12、14、16、18）。本系列由十三种化合物组成，其中 comp.C1 和 C2 显示非液晶性质，而 comp.C3 至 C7 显示 SmC 相，comp.C8 至 C18 仅显示向列相。目前合成的化合物的纹理图案是纹状和螺纹型。所有这些化合物都通过元素分析、FT-IR 和 1H NMR 进行了很好的表征。本合成化合物的相变温度通过光学偏光显微镜(POM)、差示扫描量热法(DSC)测定。详细的 XRD 研究证实了在高级同系物中存在向列相，在低级同系物中存在 SmC 相。结果表明，以酯为连接单元的查耳酮有利于分子中的棒状液晶行为。为了获得更多见解，进行了基于 DFT 的 HOMO、LUMO 研究，这些研究支持此类介晶中的分子内电荷转移相互作用。与相应的标准药物相比，基于查耳酮酯的化合物

  Novel polycatenar liquid crystals containing two 1,3,4-thiadiazole rings interconnected by an azobenzene central linkage have been synthesized and investigated by polarizing microscopy, DSC, X-ray scattering, SEM, UV-vis spectroscopy and photoluminescence measurements. These compounds can self-assemble into SmC, Colhex/p6mm and CubI/Pmn liquid crystalline phases in the bulk states and form multistimuli

  通过偏光显微镜，DSC，X射线散射，SEM，UV-vis光谱和光致发光测量，合成并研究了新颖的包含两个通过偶氮苯中心键相互连接的1,3,4-噻二唑环的聚对二甲苯液晶。这些化合物可以在本体状态下自组装为SmC，Col hex / p 6 mm和Cub I / Pm n液晶相，并在有机溶剂中形成多刺激响应性有机凝胶。它们在溶液，液晶态和凝胶态下具有可逆的光响应特性。它们还显示出溶液中斯托克斯位移大的荧光发射以及对Cu 2+的结合选择性在CH 3 CN–CH 2 Cl 2溶液中的一系列阳离子中。
• Discotic metallomesogens: mesophase crossover of columnar rectangular to hexagonal arrangements in bis(hydrazinato)nickel(II) complexes

  Three series ofN-(3,4-dialkoxybenzylidene)-N′-(3′,4′,5′-trialkoxybenzoyl)hydrazine and their nickel(ii) complexes, bis[N-(3,4-dialkoxybenzylidene)-N′-(3′,4′,5′-trialkoxybenzoyl)hydrazinato]nickel(ii), were prepared and characterized. The mesomorphic properties of these disc-like compounds were also studied in terms of liquid crystallinity. The orange nickel(ii) complexes with ten soft alkoxy side chains exhibited columnar disordered mesophases, which were characterized based on DSC analysis and optical polarized microscopy. Nickel complexes with shorter side chains (n=5–8) displayed a monotropic columnar rectangular disordered (Colrd) phase; however, complexes with longer side chains showed monotropic (n=10) and enantiotropic (n=12, 14) columnar hexagonal disordered (Colhd) phases. Similar nickel complexes (n=14) with eight side chains exhibited a columnar hexagonal phase, whereas complexes (n=14) with six side chains formed crystalline phases. The structures of these columnar disordered phases were confirmed by X-ray powder diffraction. XRD data indicated that mesophase crossover from columnar rectangular (Colr) to hexagonal arrangements (Colh) was observed with increasing side chain lengths.

  合成了三种系列的N-(3,4-二烷氧基亚苄基)-N′-(3′,4′,5′-三烷氧基苯甲酰)酰肼及其镍(II)配合物,[N-(3,4-二烷氧基亚苄基)-N′-(3′,4′,5′-三烷氧基苯甲酰)酰氨基]合镍(II),并对化合物进行了表征。我们还研究了这些类圆盘状化合物的液晶特性。具有十个柔软烷氧基侧链的橙色镍(II)配合物表现出柱状无序液晶相,这一特性通过DSC分析和光学偏振显微镜得到了表征。含有较短侧链(n=5–8)的镍配合物呈现出单变型柱状矩形无序(Colrd)相;然而,具有更长侧链的配合物呈现出单变型(n=10)和同变型(n=12, 14)柱状六方无序(Colhd)相。类似镍配合物(n=14)具有8个侧链时出现柱状六方相,而6个侧链时则形成晶态相。这些柱状无序相的结构通过X射线粉末衍射得到了确认。XRD数据显示,随着侧链长度的增加,液晶相从柱状矩形(Colr)转变为六方排列(Colh)。

  Several new enaminoketone mesogens were synthesized and coordinated to various metal salts to yield a variety of novel rodlike metal-containing liquid crystals. The mesophases were characterized by polarized optical microscopy (POM), differential scanning calorimetry (DSC) and small-angle X-ray scattering (SAXS). Whereas the free ligands display SmA and nematic mesophases, the NiII and PdII complexes give rise to SmC and nematic phases, and the paramagnetic CuII mesogens to a narrow temperature-range nematic mesophase only. The magnetic behaviour of the latter was studied by means of EPR and magnetic susceptibility (SQUID) measurements.

  assess in solution the presence of the complexes and their tetrameric composition. All the complexes display mesogenic ability, and their mesomorphic organization has been studied by X-ray diffraction and CD spectroscopy. Results allow us to propose a helical columnar model for the mesophase originated from a propeller-like conformation of the supramolecular complexes.

  此处介绍的研究结果展示了使用液晶和介晶状态中涉及的相互作用来构建复杂分子组织的新示例。我们采用了一种设计策略，其中氢键允许三聚氰胺的 pi 堆积趋势和 V 形分子的横向相互作用能力相结合，这已通过向列、近晶或柱状中间相得到广泛证明。这种组合解决了具有固有螺旋组织的柱状排列的形成。在这项工作中，具有类似于香蕉液晶结构的非介晶和介晶 V 型酸以 3 比 1 的比例与 2,4,6-三氨基-1,3,5-三嗪衍生物络合， 分别。由此获得了氢键超分子，其在溶液中的形成和稳定性已通过红外和核磁共振技术得到证实。DOSY 实验使我们能够在溶液中评估复合物的存在及其四聚体组成。所有配合物都显示出介晶能力，并通过 X 射线衍射和 CD 光谱研究了它们的介晶组织。结果使我们能够为源自超分子复合物的螺旋桨状构象的中间相提出螺旋柱状模型。并通过 X 射线衍射和 CD 光谱研究了它们的介晶组织。结果使我们能够为源自超

  The merger of ionic liquid and liquid crystal fields, obtained by using the imidazolium ring as a common element, has allowed us to tailor a new set of materials which associate specific functionalities. These functionalities are consequences of the original properties of the component, ionic liquids, liquid crystals and their association in a single compound. The study of this interesting association led us to elaborate environment-flexible cationic architectures from which mesomorphic properties emerge. Moreover, we have also explored the influence of different anions on the mesomorphic properties.
