Herein we describe the synthesis of a series of new potent tachykinin NK2 receptor antagonists by the modulation of the C‐ and N‐terminal moieties of ibodutant (MEN 15596, 1). The N‐terminal benzo[b]thiophene ring was replaced by different substituted naphthalenes and benzofurans, while further modifications were evaluated at the C‐terminal tetrahydropyran moiety. Most compounds demonstrated a high affinity
本文中,我们描述了一系列新的有效速激肽NK的合成2通过ibodutant的C-和N-末端部分的调制(MEN 15596,受体拮抗剂1)。N末端的苯并[ b ]噻吩环被不同的取代萘和苯并呋喃取代,同时在C末端的四氢吡喃部分评估了进一步的修饰。大多数化合物表现出对人NK 2受体的高亲和力和体外拮抗剂的高效力,表明可以在分子的两个末端引入广泛的取代基,而不会影响与NK 2受体的相互作用。对选定的化合物进行了体内测试,证实了其作为NK的活性2个拮抗剂。特别是,对豚鼠静脉内和静脉内给药后,化合物61b能够拮抗NK 2诱导的结肠收缩,其作用力和作用持续时间与参考化合物1(MEN 15596,ibodutant)完全相同。
