3-dioxygenase 1 (IDO1) is closely related to the over expression of many cancers, and is therefore a promising target for tumor immunotherapy. To search for novel IDO1-targeting therapeutic agents, 22 icotinib-linked 1,2,3-triazole derivatives were prepared and evaluated for their inhibitory activity against IDO1. The structures of the prepared compounds were confirmed with1H NMR, 13C NMR and HR MS. IDO1 inhibitory
近年来,肿瘤免疫疗法被认为是癌症治疗的重点。吲哚胺2,3-二加氧酶1(IDO1)与许多癌症的过度表达密切相关,因此是肿瘤免疫疗法的有希望的靶标。为了寻找靶向IDO1的新型治疗剂,制备了22种与icotinib连接的1,2,3-三唑衍生物,并评估了其对IDO1的抑制活性。通过1 H NMR,13 C NMR和HR MS确认了制备的化合物的结构。IDO1抑制活性测定结果表明,其中10种化合物对IDO1表现出显着的抑制活性,其中a17最有效,IC 50值为0.37μM。通过分子模拟研究了所制备化合物与IDO1的结合模型。当前的研究表明,icotinib-1,2,3-三唑衍生物可以用作潜在抑制剂,通过与血红素铁形成配位键而优先结合IDO1的亚铁形式。
