In this letter, we reported the design and synthesis of three potent, selective, and orally bioavailable 11β-HSD1 inhibitors labeled with 14C: AMG 456 (1), AM-6949 (2), and AM-7715 (3). We evaluated the covalent protein binding of the labeled inhibitors in human liver microsomes in vitro and assessed their potential bioactivation risk in humans. We then studied the in vitro mechanism of 2 in human
在这封信中,我们报道了标记为14 C的三种有效,选择性和口服生物利用的11β-HSD1抑制剂的设计和合成:AMG 456(1),AM-6949(2)和AM-7715(3)。我们评估了人类肝微粒体中标记的抑制剂的共价蛋白结合,并评估了其在人体中潜在的生物激活风险。然后,我们研究了人类肝细胞中2的体外机制以及反应性中间体的形成。我们的研究结果表明1和3具有较低的人类代谢生物激活潜力,而2具有较高的风险。
