therapeutic target for the treatment of cancer, chronic viral infections and neurological disorders characterized by pathological immune stimulation. Herein, a series of known metal-chelating ubiquinone derivatives were designed, synthesized and evaluated for the IDO1 inhibiting activities. The docking studies showed that the compounds 11, 16, 18 and coenzyme-Q1 exhibited different binding modes to IDO1 protein
吲哚胺 2,3-双加氧酶 1 (IDO1) 是治疗癌症、慢性病毒感染和以病理免疫刺激为特征的神经系统疾病的有吸引力的治疗靶点。在此,设计、合成和评估了一系列已知的金属螯合泛醌衍生物的 IDO1 抑制活性。对接研究表明,化合物11、16、18和辅酶-Q1对IDO1蛋白表现出不同的结合模式。在这些化合物中,活性最强的化合物是 16d,在酶促测定中的 IC50 为 0.13 μM。结果表明,溴原子 (3-Br) 和 Cys129 之间可能存在的卤素键相互作用显着增强了对 IDO1 的抑制活性。
