thieno[3,2-b]pyridinyl urea derivatives as novel and potent urotensin-II receptor antagonists are described. An activity optimization study, probing the effects of substituents on thieno[3,2-b]pyridinyl core and benzyl group of the piperidinyl moiety, led to the identification of p-fluorobenzyl substituted thieno[3,2-b]pyridinyl urea 6n as a highly potent UT antagonist with an IC50 value of 13 nM.
描述了噻吩并[3,2- b ]吡啶基脲衍生物作为新型和有效的尿紧张素-II受体拮抗剂的制备方法和SAR曲线。进行活性优化研究,探索取代基对噻吩并[3,2- b ]吡啶基核心和哌啶基部分的苄基的影响,从而鉴定出对-氟苄基取代的噻吩并[3,2- b ]吡啶基尿素6n为一种高效的UT拮抗剂,IC 50值为13 nM。尽管6n表现出良好的代谢稳定性和低的hERG结合活性,但其口服生物利用度却不可接受。
