We pursued a structure-guided approach toward the development of improved dihydroorotate dehydrogenase (DHODH) inhibitors with the goal of forming new interactions between DHODH and the brequinar class of inhibitors. Two potential residues, T63 and Y356, suitable for novel H-bonding interactions, were identified in the brequinar-binding pocket. Analogues were designed to maintain the essential pharmacophore
我们追求一种结构导向的方法来开发改进的二氢乳清酸脱氢酶 (DHODH) 抑制剂,目标是在 DHODH 和 brequinar 类抑制剂之间形成新的相互作用。在 brequinar 结合口袋中鉴定了两个潜在的残基,T63 和 Y356,适用于新的 H 键相互作用。类似物旨在维持基本的药效团并通过战略性定位的氢键接受基团形成新的静电相互作用。这一努力导致发现了有效的基于喹啉的类似物41 (DHODH IC 50 = 9.71 ± 1.4 nM) 和43 (DHODH IC 50 = 26.2 ± 1.8 nM)。43之间的共晶结构DHODH 描述了一种新的水介导的与 T63 的氢键相互作用。额外的优化导致 1,7-萘啶46 (DHODH IC 50 = 28.3 ± 3.3 nM) 与 Y356 形成新的氢键。重要的是,化合物41具有显着的口服生物利用度 ( F = 56%) 和消除t 1/2
