  Potent and Selective Agonists of Sphingosine 1-Phosphate 1 (S1P₁): Discovery and SAR of a Novel Isoxazole Based Series

  摘要：

  Sphingosine 1-phosphate (S1P) is the endogenous ligand for the sphingosine 1-phosphate receptors (S1P(1-5)) and evokes a variety of cellular responses through their stimulation. The interaction of S1P with the S1P receptors plays a fundamental physiological role in a number of processes including vascular development and stabilization, lymphocyte migration, and proliferation. Agonism of S1P(1), in particular, has been shown to play a significant role in lymphocyte trafficking from the thymus and secondary lymphoid organs, resulting in immunosuppression. This article will detail the discovery and SAR of a potent and selective series of isoxazole based full agonists of S1P(1). Isoxazole 6d demonstrated impressive efficacy when administered orally in a rat model of arthritis and in a mouse experimental autoimmune encephalomyelitis (EAE) model of multiple sclerosis.

• A New Synthetic Method of Alkyl Carbonocyanidate<i>N</i>-Oxides
  作者：Tomio Shimizu、Yoshiyuki Hayashi、Kazuhiro Teramura

  日期：1985.9

  A thermal decomposition of dimethyl nitromalonate to bis(carbomethoxy)furoxan was observed at about 170 °C. In the presence of dipolarophiles, an intermediate, methyl carbonocyanidate N-oxide MeOCOC≡N→O, could be trapped as cycloadducts in good yields by the 1,3-dipolar cycloaddition. Treatment of dimethyl nitromalonate in mesitylene at the refluxing temperature resulted in a formation of methyl 2-(hydroxyimino)-2-(2,4,6-trimethylphenyl)acetate.

  在约170°C下，观察到了二甲基硝基丙二酸酯的热分解反应，生成了双(羧甲酯)呋喃唑烷。在存在偶极亲电试剂的情况下，可以通过1,3-偶极环加成反应以良好产率捕获作为环加合物的中间体，即甲基碳二腈N-氧化物MeOCOC≡N→O。将二甲基硝基丙二酸酯在均三甲苯中回流处理，导致了甲基2-(羟基亚氨基)-2-(2,4,6-三甲基苯基)乙酸酯的形成。
