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
