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
吲哚胺2,3-二加氧酶1(IDO1)在肿瘤免疫逃逸中起着至关重要的作用,并已成为癌症免疫疗法的有希望的靶标。在这项研究中,设计,合成和评估一系列新的2,5-二甲基呋喃-3-羧酸衍生物对IDO1的抑制活性,并研究了它们的结构-活性关系。其中,化合物19a表现出优异的IDO1抑制活性(HeLa细胞IC50 = 4.0 nM,THP-1细胞IC50 = 4.6 nM)。进一步的分子对接研究表明,化合物19a通过羧酸部分与血红素铁形成了配位键。这些结果表明化合物19a是潜在的IDO1抑制剂,需要进一步研究。
