The search for selective opioid ligands with desired pharmacological potency and improved safety profile has always been an area of interest. Our previous effort yielded a potent opioid modulator, NAN, a 6α-N-7′-indolyl-substituted naltrexamine derivative, which exhibited promising pharmacological activities both in vitro and in vivo. However, significant human ether-a-go-go-related gene (hERG) liability
寻找具有所需药理效力和改善安全性的选择性阿片类配体一直是人们感兴趣的领域。我们之前的努力产生了一种有效的阿片类调节剂 NAN,一种 6α- N -7'-吲哚基取代的纳曲胺衍生物,在体外和体内均表现出有前景的药理活性。然而,人类以太相关基因(hERG)的重大责任限制了其进一步发展。因此,对NAN进行了系统的结构修饰,以减轻hERG毒性,同时保留药理特性,从而发现了2'-甲基吲哚基衍生化合物21。与 NAN 相比,化合物21表现出整体改善的药理学特征。后续 hERG 通道抑制评估显示,与 NAN 相比,化合物21的效力降低了七倍。此外,一些基本的类药特性评估表明合理的 ADME 概况为21。总的来说,化合物21似乎是一种有前途的阿片类调节剂,可进一步开发为阿片类药物使用障碍治疗的新型治疗剂。
