A series of exiguamine A analogues were designed and synthesized via 15 steps. Their inhibitory activities against IDO1 were tested and the structure-activity relationships were studied. Most compounds exhibited potent IDO1 inhibitory activities with IC50 values at the level of 10−7–10−8 M. Compound 21f was the most potent IDO1 inhibitor with an IC50 value of 65.3 nM, which was comparable with the
通过 15 个步骤设计和合成了一系列 exiguamine A 类似物。测试了它们对 IDO1 的抑制活性,并研究了构效关系。大多数化合物表现出有效的 IDO1 抑制活性,IC 50值为 10 -7 –10 -8 M。化合物21f是最有效的 IDO1 抑制剂,IC 50值为 65.3 nM,与阳性对照药物 epacadostat 相当(IC 50 = 46 nM)。此外,化合物21f对 IDO1 显示出比色氨酸 2,3-双加氧酶 (TDO) 更高的选择性,并且在其有效浓度下没有细胞毒性,这使其有理由进一步优化和评估。
