  Design, synthesis and In vitro evaluation of potent, novel, small molecule inhibitors of plasminogen activator inhibitor-1

  摘要：

  We have synthesized and evaluated a series of tetramic acid-based and hydroxvquinolinone-based inhibitors of plasminogen activator inhibitor-1 (PAI-1). These studies resulted in the identification of several compounds which showed excellent potency against PAI-1. The design, synthesis and SAR of these compounds are described.

  发现具有柔性接头的地苯氧基衍生物作为 β-淀粉样蛋白斑的配体。

  摘要：

  具有 π 共轭系统的高度刚性和平面支架已被广泛认为是 β-淀粉样蛋白 (Aβ) 结合配体必不可少的。在这项研究中，合成并评估了具有不同类型的更灵活的接头作为 Aβ 配体的二苯氧基化合物库。它们中的大多数对 Aβ 1-42聚集体显示出良好的亲和力 ( K i < 100 nM) ，一些配体甚至显示出K i值小于 10nM。构效关系分析表明，接头或取代基的修饰具有很大的灵活性，这挑战了长期以来认为刚性和平面结构专用于 Aβ 结合的观点。三种配体被碘125标记，它们在体外和体内表现出良好的特性，进一步支持这种柔性支架在Aβ成像剂的开发中具有潜力和前景。

• Bifunctional reactivity of the nitrophenoxyl group in intramolecular photoreactions

  The photochemical behavior of a homologous series of compounds, p-O2NC6H4O(CH2)(n)NHPh (n = 2-10, 12, and 16) in acetonitrile is reported. The lower (n = 2-6) homologues undergo an apparently nucleophilic type rearrangement to give omega-((p-nitrophenyl)amino)alkanol, while the higher homologues (n greater-than-or-equal-to 8) undergo an intramolecular photoredox reaction accompanied by C-N bond cleavage to give omega-(p-nitrosophenoxy)alkanal and aniline. The n = 7 homologue is situated at the switching point of these two reaction pathways, exhibiting neither type of photoreactions. Photoinduced intramolecular electron transfer to generate a radical ion pair is observed for all homologues, and the quantum yield decreases with increasing chain length. This species is the intermediate in the photorearrangement, for which the effect of base-catalysis is discussed in connection with the reaction mechanism. Comparison of the quantum yield for the electron transfer in 1 with that in 1-(anilinomethyl)-4-((p-nitrophenoxy)methyl)cyclohexane reveals the dominance of through-bond electron-transfer mechanism in the higher (n greater-than-or-equal-to 6) homologues. The reaction quantum yield vs chain length profile is discussed in terms of the relative quantum yield of the radical ion pair, the chain conformation, and the photoredox reaction mechanism.
• Liquid Crystalline Properties of 6-(4-Cyanobiphenyl-4’-yloxy)hexyl 4’-[ω-(<i>p</i>-Nitrophenyloxy)alkoxy]-4-biphenylcarboxylates

  A new series of liquid crystalline compounds, which contained two biphenyl and one p-nitrophenyl groups linked by two flexible spacers, were prepared. The flexible spacer between two biphenyl groups is fixed and consists of nine (odd number) atoms. The compounds showed nematic phase, although some of them exhibited nematic and smectic phases upon cooling. The isotropic-nematic transitional properties depended on the length and parity of the flexible spacers between the biphenyl and p-nitrophenyl groups. Such odd-even effect was in consistency with the feature of liquid crystal trimers. The liquid crystalline properties were compared with those of the related compounds.

  Many G protein-coupled receptors (GPCRs), including the adenosine A(1) receptor (A(1)AR), have been shown to be allosterically modulated by small molecule ligands. So far, in the absence of structural information, the exact location of the allosteric site on the A(1)AR is not known. We synthesized a series of bivalent ligands (4) with an increasing linker length between the orthosteric and allosteric pharmacophores and used these as tools to search for the allosteric site on the A(1)AR. The compounds were tested in both equilibrium radioligand displacement and functional assays in the absence and presence of a reference allosteric enhancer, (2-amino-4,5-dimethy1-3-thienyl)-[3-(trifluoromethyl)phenyl]methanone, PD81,723 (1). Bivalent ligand N-6-[2-amino-3-(3,4-dichlorobenzoyl)-4,5,6,7-tetrahydrothieno[2,3-c]-pyridin-6-yl-9-nonyloxy-4-phenyl]-adenosine 4h (LUF6258) with a 9 carbon atom spacer did not show significant changes in affinity or potency in the presence of 1, indicating that this ligand bridged both sites on the receptor. Furthermore, 4h displayed an increase in efficacy, but not potency, compared to the parent, monovalent agonist 2. From molecular modeling studies, we speculate that the allosteric site of the A(1)AR is located in the proximity of the orthosteric site, possibly within the boundaries of the second extracellular loop of the receptor.

  analysis revealed that modification on the linkers or substituents tolerated great flexibility, which challenged the long-held belief that rigid and planar structures are exclusively favored for Aβ binding. Three ligands were labeled by iodine-125, and they exhibited good properties in vitro and in vivo, which further supported that this flexible scaffold was potential and promising for the development
