The synthesis, nAChR in vitro and in vivo pharmacological properties of 2′-fluoro-3′-(substituted thiophenyl)deschloroepibatidine analogues (5a–f, 6a–d, and 7a–c) are presented herein. All had subnanomolar affinity at α4β2*-nAChRs. Contrary to lead structure epibatidine, a potent nAChR agonist, all were potent α4β2- and α3β4-AChR antagonists in an in vitro functional assay. In vivo, the compounds were
本文介绍了2'-氟-3'-(取代的硫代苯基)去氯表艾巴替丁类似物(5a – f,6a – d和7a – c)的合成,nAChR的体内和体外药理特性。它们都对α4β2* -nAChRs具有亚纳摩尔亲和力。在体外功能测定中,与有效的nAChR激动剂前导结构Epibatidine相反,它们都是有效的α4β2-和α3β4-AChR拮抗剂。在体内,该化合物也是具有各种程度激动剂活性的nAChR拮抗剂。化合物5e,5f,6a,6c,6d和7c在甩尾,热板,体温过低或自发活动测试中没有激动剂作用,而5a – d,7a和7b在甩尾和热板测试中没有激动剂活性,但与伐尼克兰一样激动剂在低温和自发活动测试中。化合物6b在所有四个体内试验中均具有激动剂活性。在甩尾试验中,所有化合物均为烟碱诱导的抗伤害感受的拮抗剂,而在热板试验中,除5c,5d,5f和6b以外的所有化合物均为烟碱诱导的抗伤害感受的拮抗剂。具有K的化合物7c在结合试验中,i
