Adamantanyl benzamide 1 was identified as a potent P2X7R antagonist but failed to progress further due to poor metabolic stability. We describe the synthesis and SAR of a series of bioisosteres of benzamide 1 to explore improvements in the pharmacological properties of this lead. Initial efforts investigated a series of heteroaromatic bioisosteres, which demonstrated improved physicochemical properties
精金刚烷苯甲酰胺1被确定为有效的P2X 7 R拮抗剂,但由于代谢稳定性差而未能进一步发展。我们描述了一系列苯甲酰胺1的生物等排体的合成和SAR,以探索这种铅的药理特性的改善。最初的努力研究了一系列杂芳族生物等排体,它们显示出改善的理化性质,但减少了P2X 7 R拮抗作用。在金刚烷桥头上安装了生物立体异构的氟是很好的耐受性,并导致了一系列具有改善的理化性质和代谢稳定性的生物立体异构体。三氟苯甲酰胺34证明了最佳的物理化学参数,优异的代谢稳定性(比苯甲酰胺铅1的长十倍)和改善的物理动力学特性,并被证明在存在几种已知的P2X 7 R多态性时有效。
