  Development of Amidine-Based Sphingosine Kinase 1 Nanomolar Inhibitors and Reduction of Sphingosine 1-Phosphate in Human Leukemia Cells

  摘要：

  Sphingosine 1-phosphate (S1P) is a bioactive lipid that has been identified as an accelerant of cancer progression. The sphingosine kinases (SphKs) are the sole producers of S1P, and thus, SphK inhibitors may prove effective in cancer mitigation and chemosensitization. Of the two SphKs, SphK1 overexpression has been observed in a myriad of cancer cell lines and tissues and has been recognized as the presumptive target over that of the poorly characterized SphK2. Herein, we present the design and synthesis of amidine-based nanomolar SphK1 subtype-selective inhibitors. A homology model of SphK1, trained with this library of amidine inhibitors, was then used to predict the activity of additional, more potent, inhibitors. Lastly, select amidine inhibitors were validated in human leukemia U937 cells, where they significantly reduced endogenous S1P levels at nanomolar concentrations.

  通过 C3 炔丙基亲电试剂的意外二聚/聚合序列合成聚二炔

  摘要：

  在这里，我们描述了意外发现的炔丙基亲电试剂 (CPPE) 的铜催化缩聚反应，该反应将简单的 C3 结构单元转化为 C6 重复单元的聚二炔。该反应是通过由铜乙炔化物引发剂和富电子膦配体组成的简单系统实现的。炔烃聚合物（高达 33.8 kg/mol）以良好的收率和独特的区域选择性和高官能团相容性生产。产物的氢化提供了一种新的聚烯烃型骨架，而碱介导的异构化则产生了一种新型的二烯基缺电子共轭聚合物。机理研究揭示了一种新的 α-α 选择性 Cu 催化的 C3 单元二聚化途径，随后是原位有机铜介导的链增长。这些见解不仅提供了对 C3、C4 和 C6 单体的铜催化 CPPE 的重要理解，而且还显着改进了从更简单的起始材料合成聚二炔的过程，这些起始材料具有用于结合 α 端官能团的手柄.

  especially good activity. Conformational restriction of either the polar region or lipid tail produced compounds devoid of activity. A number of selected analogues were also evaluated in vivo as antagonists of LTD4-induced bronchoconstriction in the guinea pig. The data established these compounds as a novel class of leukotriene antagonists with potential utility for the treatment of asthma and other immediate

  A series of 1,3,5-triaryl-2-pyrazolines was synthesized by dissolving the corresponding 4-alkoxychalcones in glacial acetic acid containing a few drops of concentrated hydrochloric acid. This step was followed by the addition of (3,4-dimethylphenyl) hydrazaine hydrochloride. Finally the target compounds were precipitated by pouring the reaction mixture onto crushed ice. The structures of the synthesized compounds were established by physicochemical and spectroscopic methods. The 1,3,5-triaryl-2-pyrazolines bearing homologous alkoxy groups were found to possess fluorescence properties in the blue region of the visible spectrum when irradiated with ultraviolet radiation. The fluorescent behavior of these compounds was studied by UV-Vis and emission spectroscopy, performed at room temperature.
