of 5‐phenylsulfanyl‐ and 5‐benzyl‐substituted tetrahydro‐2‐benzazepines was synthesized and pharmacologically evaluated. Key steps of the synthesis were the Heck reaction, the Stetter reaction, a reductive cyclization, and the introduction of diverse N substituents at the end of the synthesis. High σ1 affinity was achieved for 2‐benzazepines with linear or branched alk(en)yl residues containing at least
根据通过连接C6-C1和C3- N构件生成2-苯并ze庚因骨架的新策略,合成了一组5-苯硫基和5-苄基取代的四氢-2-苯并ze庚因,并进行了药理学评估。合成的关键步骤是Heck反应,Stetter反应,还原环化以及在合成结束时引入各种N取代基。高σ 1个亲和性2-苯并吖庚因与直链或含有至少一个支链的烷(烯)基的残基来实现Ñ丁基子结构。丁基和4-氟苄基取代的衍生物(±)-5-苄基-2-丁基-2-3,4,5-四氢-1 H -2-苯并H庚因(19 b)和(±)-5-苄基-2-(4-氟苄基)-2,3,4,5-四氢-1 H -2-苯并ze庚因(19 m)对50多个其他相关目标具有高选择性,包括σ 2亚型和各种结合位点ñ甲基d天冬氨酸(NMDA)受体。在欧文(Irwin)屏幕中,19 b和19 m显示出干净的轮廓,而没有引起明显的副作用。化合物19b的和19米没有透露显著镇痛和认知增强活动。化合物19
