iterative process of synthesis and screening led to cyclized analog 21 (IDO1 HeLa IC50 = 3.6 nM) which maintained the high potency of 3 while addressing issues of lipophilicity, cytochrome P450 (CYP) inhibition, hERG (human potassium ion channel Kv11.1) inhibition, Pregnane X Receptor (PXR) transactivation, and oxidative metabolic stability. An x-ray crystal structure of a biaryl alkyl ether 11 bound to IDO1
从二烷基苯胺吲哚胺 2,3-双加氧酶 1 (IDO1) 抑制剂先导物3 (IDO1 HeLa IC 50 = 7.0 nM) 开始,合成和筛选的迭代过程导致环化类似物21 (IDO1 HeLa IC 50 = 3.6 nM),维持3的高效力,同时解决亲脂性、细胞色素 P450 (CYP) 抑制、hERG(人钾离子通道 Kv11.1)抑制、孕烷 X 受体 (PXR)反式激活和氧化代谢稳定性等问题。获得了与 IDO1 结合的联芳基烷基醚11的 X 射线晶体结构。与我们之前的结果一致,化合物11显示与酶的apo形式结合。
