  Synthesis and biological activity of a series of diaryl-substituted .alpha.-cyano-.beta.-hydroxypropenamides, a new class of anthelmintic agents

  摘要：

  A series of alpha-cyano-beta-hydroxypropenamides was prepared and tested for anthelmintic activity. Alpha-cyano-beta-hydroxy hydroxy-N-[4-(trifluoromethyl)phenyl]-3-[4-(trifluoromethyl)phenyl]propenamide (1) showed good activity against the nematode Nematospirodes dubius in a mixed parasite infection in mice; several of the analogues were also effective against the cestode Hymenolepis nana. In sheep trials, 1 caused 100% reduction of the hematophagous nematode Haemonchus contortus after a single dose of 20 mg/kg but did not show satisfactory control of Trichostrongylus colubriformis or Ostertagia circumcincta. Against the liver fluke Fasciola hepatica, 1 suppressed egg production but only temporarily, suggesting that the adult flukes were not eliminated. Mechanism of action studies on 1 using Ascaris mitochondria showed it to be an uncoupler of oxidative phosphorylation.

  Ion selectivity is a defining feature of a given ion channel and is considered immutable. Here we show that ion selectivity of the lysosomal ion channel TPC2, which is hotly debated (Calcraft et al., 2009; Guo et al., 2017; Jha et al., 2014; Ruas et al., 2015; Wang et al., 2012), depends on the activating ligand. A high-throughput screen identified two structurally distinct TPC2 agonists. One of these evoked robust Ca2+-signals and non-selective cation currents, the other weaker Ca2+-signals and Na+-selective currents. These properties were mirrored by the Ca2+-mobilizing messenger, NAADP and the phosphoinositide, PI(3,5)P2, respectively. Agonist action was differentially inhibited by mutation of a single TPC2 residue and coupled to opposing changes in lysosomal pH and exocytosis. Our findings resolve conflicting reports on the permeability and gating properties of TPC2 and they establish a new paradigm whereby a single ion channel mediates distinct, functionally-relevant ionic signatures on demand.

  离子选择性是特定离子通道的决定性特征，被认为是不可改变的。在这里，我们证明了溶酶体离子通道 TPC2 的离子选择性取决于激活配体，这一点引起了激烈的争论（Calcraft 等人，2009 年；Guo 等人，2017 年；Jha 等人，2014 年；Ruas 等人，2015 年；Wang 等人，2012 年）。高通量筛选发现了两种结构不同的 TPC2 激动剂。其中一种能唤起强烈的 Ca2+ 信号和非选择性阳离子电流，另一种则能唤起较弱的 Ca2+ 信号和 Na+ 选择性电流。这些特性分别由 Ca2+ 迁移信使 NAADP 和磷酸肌醇 PI(3,5)P2 反映出来。单个 TPC2 残基的突变会不同程度地抑制激动剂的作用，并与溶酶体 pH 值和外泌作用的对立变化相耦合。我们的发现解决了有关 TPC2 通透性和门控特性的相互矛盾的报道，并建立了一种新的范式，即单一离子通道可根据需要介导不同的、功能相关的离子特征。
• α-Dimethylaminomethylenation-induced Houben–Hoesch-type cyclization of cyanoacetanilides: a practical synthesis of 3-formyl-4-hydroxyquinolin-2(1H)-ones

  The tandem reaction of cyanoacetanilides with triflic anhydride in DMF proceeded at room temperature to afford 3-formyl-4-hydroxyquinolin-2(1H)-ones in good to high yields. A detailed mechanistic study revealed that the tandem reaction proceeded via alpha-dimethylaminomethylenation, which promoted the subsequent Houben-Hoesch-type cyclization. Both alpha-functionalization and the cyclization steps were optimized, and a multi-gram scale synthesis of 3-formyl-4-hydroxyquinolin-2(1H)-one was achieved. (C) 2011 Elsevier Ltd.

  A concise method has been developed for the synthesis of caroverine and its derivatives. The quinoxalinone scaffold of these compounds was constructed via the tandem nitrosation/aerobic oxidative C N bond formation reaction of N-(2-chloroethyl)-2-cyano-N-phenylacetamide, followed by sequential Grignard, Finkelstein and nucleophilic substitutions reactions to give several different derivatives. Herein, we describe the development of this strategy in terms of the optimization of each step as well as the effect of different additives on the individual reactions. (C) 2014 Elsevier Ltd.

  An efficient method for constructing quinoxalinone-N-oxides from cyanoacetanilides has been developed. This transformation can be achieved using inexpensive reagents and molecular oxygen under mild conditions, thus offering a practical pathway to quinoxalinone-containing pharmaceuticals such as ataquimast and opaviraline.
