The synthesis and vascular 5-HT(1B)-like receptor activity of a novel series of substituted 2, N-benzylcarboxamido-5-(2-ethyl-1-dioxoimidazolidinyl)-N, N-dimethyltryptamine derivatives are described. Modifications to the 5-ethylene-linked heterocycle and to substituents on the 2-benzylamide side chain have been explored. Several compounds were identified which exhibited affinity at the vascular 5-HT(1B)-like
描述了一系列新的取代的2,N-苄基羧酰胺基-5-(2-乙基-1-二氧代咪唑啉基)-N,N-二甲基色胺衍生物的合成和血管5-HT(1B)-样受体活性。已经研究了对5-乙烯-连接的杂环和2-苄基酰胺侧链上的取代基的修饰。鉴定出几种化合物,它们在pK(B)> 7.0的血管5-HT(1B)样受体上表现出亲和力,选择性比alpha(1)-肾上腺素受体亲和力和5-HT(2A)受体亲和力高100倍,并且表现出良好的药代动力学特征。N-苄基-3- [2-(二甲基氨基)乙基] -5- [2-(4,4-二甲基-2,5-二氧-1-咪唑啉基)乙基] -1H-吲哚-2-羧酰胺(23)被认为是非常有力的 沉默(通过血管紧张素II无法揭露兔股动脉中的5-HT(1B)样受体介导的激动剂活性来判断)和具有血浆消除一半功能的竞争性血管5-HT(1B)样受体拮抗剂犬血浆中约4小时的寿命,并具有良好的口服生物利用度。讨论了该系列
