  可循环利用的粘土负载的Cu（II）催化串联一锅合成1-芳基-1,2,3-三唑

  摘要：

  蒙脱土KSF粘土负载的CuO纳米颗粒可有效催化芳基硼酸的一锅芳香叠氮，然后在室温下进行区域选择性叠氮化物-炔烃1,3-偶极环加成（CuAAC）反应，生成相应的1-芳基-1,2,3-三唑衍生物在不使用任何添加剂的情况下，收率极高。CuAAC机理的研究表明，叠氮化钠在一锅法中用作叠氮化试剂，可将Cu（II）还原为点击活性Cu（I）。另一种Cu（II）源CuSO 4与NaN 3结合对该单锅CuAAC方案的催化效率进一步支持了我们的机理。这是关于使用Cu（II）/ NaN 3的第一份报告CuAAC方案的催化系统。粘土-铜（II）催化剂无配体，无浸出，易于从廉价的市售前体合成，可回收且对环境友好，对于经济合成1,4-二取代1,2,3-将非常有用。三唑。

  1,4-Dihydroxyanthraquinone–copper(II) supported on a superparamagnetic Fe3O4@SiO2 catalyst was employed for the N-arylation of nitrogen heterocycles and alkylamines with aryl halides to afford the corresponding coupled products in good to excellent yields without using external ligands or additives as promoters. Also, we have reported this recyclable catalytic system for efficient synthesis of 1-aryl-1

  The design, synthesis, and evaluation of the potency of new isoform-selective inhibitors of sphingosine kinases I and 2 (SK1 and SK2), the enzyme that catalyzes the phosphorylation of D-erythro-sphingosine to produce the key signaling lipid, sphingosine 1-phosphate, are described. Recently, we reported that 1-(4-octylphenethyl)piperidin-4-ol (RB-005) is a selective inhibitor of SK1. Here we report the synthesis of 43 new analogues of RB-005, in which the lipophilic tail, polar headgroup, and linker region were modified to extend the structure-activity relationship profile for this lead compound, which we explain using modeling studies with the recently published crystal structure of SKI. We provide a basis for the key residues targeted by our profiled series and provide further evidence for the ability to discriminate between the two isoforms using pharmacological intervention.

  Macrophage migration inhibitory factor (MIF) is a versatile protein that plays a role in inflammation, autoimmune diseases and cancers. Development of novel inhibitors will enable further exploration of MIF as a drug target. In this study, we investigated structure-activity relationships of MIF inhibitors using a MIF tautomerase activity assay to measure binding. Importantly, we notified that transition metals such as copper (II) and zinc (II) interfere with the MIF tautomerase activity under the assay conditions applied. EDTA was added to the assay buffer to avoid interference of residual heavy metals with tautomerase activity measurements. Using these assay conditions the structure-activity relationships for MIF binding of a series of triazole-phenols was explored. The most potent inhibitors in this series provided activities in the low micromolar range. Enzyme kinetic analysis indicates competitive binding that proved reversible. Binding to the enzyme was confirmed using a microscale thermophoresis (MST) assay. Molecular modelling was used to rationalize the observed structure-activity relationships. The most potent inhibitor 2d inhibited proliferation of A549 cells in a clonogenic assay. In addition, 2d attenuated MIF induced ERK phosphorylation in A549 cells. Altogether, this study provides insights in the structure-activity relationships for MIF binding of triazole-phenols and further validates this class of compounds as MIF binding agents in cell-based studies.

  Sphingosine 1-phosphate (S1P) is involved in hyper-proliferative diseases, such as cancer and vascular remodeling in pulmonary arterial hypertension. Inhibitors of sphingosine kinase 1 and 2 (SK1 and SK2), which catalyze the synthesis of S1P, may be useful anti- proliferative agents. We have synthesized a series of sphingosine-based inhibitors of SK and SK2. Also provided in this invention are compounds that activate SK1 which can be used in diseases such as fibrosis, where intracellular S1P is anti-fibrotic.
