Indoleamine 2,3-dioxygenase 1 (IDO1) plays a vital role in tumor immune escape and has emerged as a promising target for cancer immunotherapy. In this study, a novel series of 2,5-dimethylfuran-3-carboxylic acid derivatives were designed, synthesized and evaluated for inhibitory activities against IDO1, and their structure-activity relationship was investigated. Among these, compound 19a exhibited excellent IDO1 inhibitory activity (HeLa cellular IC = 4.0 nM, THP-1 cellular IC = 4.6 nM). Further molecular docking studies revealed that the compound 19a formed a coordinate bond with the heme iron through the carboxylic acid moiety. These results indicate that compound 19a is a potential IDO1 inhibitor for further investigation.
吲哚胺 2,3-双加氧酶 1（IDO1）在肿瘤免疫逃逸中发挥着重要作用，已成为癌症免疫治疗的一个有前途的靶点。在这项研究中，设计、合成了一系列新型的 2,5-二甲基呋喃-3-羧酸衍生物，并对其抑制 IDO1 的活性进行了评价，探讨了它们的构效关系。其中，化合物 19a 表现出优异的 IDO1 抑制活性（HeLa 细胞 IC=4.0nM，THP-1 细胞 IC=4.6nM）。进一步的分子对接研究表明，该化合物通过羧酸部分与亚铁血红素形成配位键。这些结果表明，化合物 19a 是一种潜在的 IDO1 抑制剂，值得进一步研究。
