Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid metabolite that regulates a multitude of physiological processes such as lymphocyte trafficking, cardiac function, vascular development, and inflammation. Because of the ability of S1P1 receptor agonists to suppress lymphocyte egress, they have great potential as therapeutic agents in a variety of autoimmune diseases. In this article, the discovery
鞘氨醇-1-磷酸酯(S1P)是一种具有生物活性的鞘脂代谢产物,可调节多种生理过程,例如淋巴细胞运输,心脏功能,血管发育和炎症。由于S1P 1受体激动剂具有抑制淋巴细胞流出的能力,因此它们在多种自身免疫性疾病中具有作为治疗剂的巨大潜力。在本文中,描述了利用包含末端羧酸的乙醇胺支架发现选择性,直接作用的S1P 1激动剂的发现。强大的S1P 1激动剂,例如化合物18a和19a,其选择性比S1P 3高1000倍以上被描述。这些化合物分别在单剂1和0.3 mpk的剂量后24小时内有效减少了大鼠的血淋巴细胞计数。讨论了这两种化合物的药效特性。在两种疾病的临床前模型中进一步研究了化合物19a,它们在大鼠佐剂性关节炎模型(AA)和小鼠实验性自身免疫性脑脊髓炎模型(EAE)中均显示出良好的疗效。
