A short stereoselective synthesis of a series of chiral 7-aryl-2,5-diketopiperazines oxytocin antagonists is described. Varying the functionality and substitution pattern of substituents in the 7-aryl ring and varying the chirality of this exocyclic ring have produced potent oxytocin antagonists (pK(i) > 8.5). SAR and pharmacokinetic profiling of this series of (3R,6R,7R)-2,5-diketopiperazines together
描述了一系列手性7-芳基-2,5-二酮哌嗪催产素拮抗剂的短立体选择性合成。改变7-芳基环中取代基的官能度和取代方式并改变该环外环的手性可产生有效的催产素拮抗剂(pK(i)> 8.5)。(3R,6R,7R)-2,5-二酮哌嗪系列的SAR和药代动力学分析以及在7-芳基环中引入邻位F基团以改善大鼠pK的结果在2',4'-二氟苯基二酮哌嗪衍生物37,一种针对人催产素受体的强效催产素拮抗剂(pK(i)= 8.9),相对于所有三种加压素受体V1a,V2和V1b具有> 1000倍的选择性。
