The inhibition of the mammalian soluble epoxide hydrolase (sEH) is a promising new therapy in the treatment of hypertension, inflammation, and other disorders. However, the problems of limited water solubility, high melting point, and low metabolic stability complicated the development of 1,3-disubstituted urea-based sEH inhibitors. The current study explored the introduction of the substituted piperazino
哺乳动物可溶性环氧化物水解酶 (sEH) 的抑制作用是治疗高血压、炎症和其他疾病的一种很有前景的新疗法。然而,有限的水溶性、高熔点和低代谢稳定性的问题使基于 1,3-二取代脲的 sEH 抑制剂的开发变得复杂。目前的研究探索了引入取代的哌嗪基团作为三级药效团,与先前报道的基于 1-金刚烷脲的抑制剂相比,这导致药代动力学参数的显着改善,同时保持高效力。SAR 研究表明,间位或对位取代的苯基间隔基和N 4-乙酰基或磺酰基取代的哌嗪是实现高效力和良好物理性能的最佳结构。1-(4-(4-(4-acetylpiperazin-1-yl)butoxy)phenyl)-3-adamantan-1-yl urea ( 29c ) 在小鼠体内表现出优异的体内药代动力学特性:T 1/2 =14 h ,C max = 84 nM,AUC = 40 200 nM·min,和 IC 50 = 7.0 nM 对人 sEH
