  Synthesis of 4(5)-phenylimidazole-based analogues of sphingosine-1-phosphate and FTY720: Discovery of potent S1P1 receptor agonists

  摘要：

  The novel immunosuppressant FTY720 has been demonstrated to elicit immunomodulating effects via interaction with the G-protein coupled receptor S1P(1). FTY720 induced agonism at the S1P(3) receptor, however, has been shown to result in mild bradycardia, a minor side-effect of initial FTY720 therapy. This report describes the synthesis of several potent 4(5)-phenylimidazole-based SIP, receptor agonists that are accompanied by poor agonist activity at S1P(3). For instance, compound 20 displayed an EC50 = 4.7 +/- 1.3 nM at the S1P(1), receptor and EC50 = 780 +/- 1.3 nM at the SIP3 receptor using a [gamma-S-35]GTP-binding assay as compared to phospho-FTY720 (S1P(1): EC50 = 1.3 +/- 1.3 nM, S1P(3): EC50 = 2.0 +/- 2.4 nM).
