  摘要：

  为了系统地探索和更好地理解二芳基甲烷骨架在设计强效尿酸转运蛋白 1 (URAT1) 抑制剂时的构效关系 (SAR)，设计并合成了 33 种化合物（1a-1x 和 1ha-1hi），并测定了它们的体外 URAT1 抑制活性 (IC50)。三轮系统的 SAR 探索导致发现了一种高效的新型 URAT1 抑制剂，1h，其效力分别比母体 lesinurad 和苯溴马隆强 200 倍和 8 倍（IC50 = 0.035 μM 对人 URAT1 1 小时 vs lesinurad 和苯溴马隆分别为 7.18 μM 和 0.28 μM）。化合物 1h 是迄今为止我们实验室发现的最有效的 URAT1 抑制剂，也可与目前正在临床试验中开发的最有效的抑制剂相媲美。
