  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.
