lic acid 13n (ceralifimod, ONO-4641), a sphingosine-1-phosphate (S1P) receptor agonist selective for S1P1 and S1P5, is described. While it has been revealed that the modulation of the S1P1 receptor is an effective way to treat autoimmune diseases such as relapsing–remitting multiple sclerosis (RRMS), it was also reported that activation of the S1P3 receptor is implicated in some undesirable effects
1-(6-[(2-甲氧基-4-丙基苄基)氧基] -1-甲基-3,4-二氢萘-2-基}甲基)氮杂环丁烷-3-羧酸13n(ceralifimod,ONO- (4641),描述了对S1P 1和S1P 5具有选择性的鞘氨醇-1-磷酸(S1P)受体激动剂。尽管已经发现调节S1P 1受体是治疗自身免疫性疾病(例如复发-缓解型多发性硬化症(RRMS))的有效方法,但也有报道称S1P 3受体的激活与某些不良作用有关。我们对命中化合物6进行了结构-活性关系(SAR)研究在亲水性头部区域具有氨基酸部分。在通过诱导构象约束力鉴定具有二氢萘中心核的先导化合物之后,亲脂性尾部区域的优化导致发现13n作为临床候选物,其对S1P 1的选择性比S1P 3高> 30 000倍,并且在小鼠外周淋巴细胞降低(PLL)测试(口服给药24小时后,ED 50 = 0.029 mg / kg)。
