Efficient chromatography-free synthesis of the oxy-analogue of fingolimod
摘要:
Fingolimod (FTY720) and its analogue derivatives are not only promising therapeutics in sphingolipid signaling but also valuable tools for understanding the roles of sphingolipids in (patho)physiological conditions. A practical method for the synthesis of the ether analogue of FTY720 is described. Our final synthetic approach allows high yield and efficient synthesis of O-FTY in only four steps without chromatographic purifications. (C) 2010 Elsevier Ltd. All rights reserved.

Novel compounds with dual S1P receptor agonist and histamine H3 receptor antagonist activities act protective in a mouse model of multiple sclerosis
3-piperidinopropyloxy moiety resembles a structural motif of pitolisant, a drug with histamine H3R antagonistic/inverse agonist activity approved for the treatment of narcolepsy. Both novel compounds exerted H3R affinities, and in addition, ST-1505 was characterised as a dual S1P1+3 agonist, whereas ST-1478 was a dual S1P1+5 agonist. Both multitargeting compounds were also active in mice and reduced the lymphocyte
鞘氨醇 1-磷酸 (S1P) 受体 1 (S1P 1 ) 已成为治疗多发性硬化症 (MS) 的治疗靶点。芬戈莫德 (FTY720) 是第一个被批准用于 MS 口服治疗的S1P 1功能性拮抗剂。以前,我们开发了 FTY720 的新型蝴蝶衍生物,其作用类似于 FTY720,可减轻实验性自身免疫性脑脊髓炎 (EAE) 小鼠模型中的疾病症状。 在这项研究中,我们合成了恶唑并恶唑化合物的哌啶衍生物,表示为 ST-1505,及其开环类似物 ST-1478,并表征了它们的体外和体内功能。值得注意的是,3-哌啶基丙氧基部分类似于 pitolisant 的结构基序,一种具有组胺 H 3 R 拮抗/反向激动剂活性的药物,已被批准用于治疗发作性睡病。两种新型化合物均表现出 H 3 R 亲和力,此外,ST-1505 被表征为双重 S1P 1+3激动剂,而 ST-1478 是双重 S1P 1+5激动剂。这两种多靶点化合物在小鼠中也有活性,并减少了
