  Efficient Synthesis of the Immunomodulating Compound KRP-203

  摘要：

  利用 XantPhos 和 Pd2(dba)3 介导的钯偶联反应作为关键步骤，实现了 KRP-203 (1) 的实用简洁合成。芳基溴 5 与 3-羟基苯硫酚（6）的偶联反应以化学选择性方式进行，生成苯酚 7，尽管 5 上存在一个氯取代基，6 上存在一个羟基。通过苄基化和去除保护基团，苯酚 7 可以高产率地转化为 KRP-203。

  Removal of Sphingosine 1-Phosphate Receptor-3 (S1P₃) Agonism is Essential, But Inadequate to Obtain Immunomodulating 2-Aminopropane-1,3-diol S1P₁ Agonists with Reduced Effect on Heart Rate

  摘要：

  A series of 2-substituted 2-aminopropane-1,3-diols having a biphenyl moiety and their phosphate esters were synthesized to obtain sphingosine 1-phosphate receptor-1 (S1P(1)) receptor agonists with potent immunomodulatory activity accompanied by little or no effect on heart rate. Many of the synthesized compounds sufficiently decreased the number of peripheral blood lymphocytes. Some of the phosphates had potent agonism at S1P(1) but no agonism at S1P(3), which had been reported to be a receptor responsible for heart rate reduction. Although high S1P(1)/S1P(3) selectivity was considered to be favorable to reduce the effect on heart rate, almost all the phosphates showed a remarkable heart rate lowering effect in vivo. The results suggest that other factors in addition to S1P(3) agonism should be responsible for the heart rate reduction caused by S1P(1) agonists. Only 2-amino-2-[2-[2'-fluoro-4'-(4-methylphenylthio)biphenyl-4-yl]ethyl]propane-1,3-diol (6d) was identified as a desired S1P(1) receptor agonist having both the immunomodulatory activity and an attenuated effect on heart rate by a unique screening flow using in vivo evaluating systems primarily.
