Indoleamine 2,3-dioxygenase 1 (IDO1) plays a vital role in the catabolism of tryptophan along with the kynurenine pathway which is involved in many human diseases including cancer, Alzheimer’s disease, etc. In this study, compound 1 bearing a 1-Indanone scaffold was identified as a novel IDO1 inhibitor by structure-based virtual screening, with moderate to good enzymatic and cellular inhibitory activities
吲哚胺2,3-双加氧酶1(IDO1)与色氨酸途径一起在色氨酸的分解代谢中起着至关重要的作用,该过程涉及许多人类疾病,包括癌症,阿尔茨海默氏病等。在这项研究中,化合物1带有1-茚满酮支架通过基于结构的虚拟筛选被鉴定为新型IDO1抑制剂,具有中等至良好的酶促和细胞抑制活性。此外,表面等离子体共振分析验证了化合物1和IDO1蛋白之间的直接相互作用。进一步探索了初步SAR,并通过实验和分子对接预测了与IDO1蛋白的结合方式。随后对这些活性化合物的ADME特性进行了计算机分析,结果显示出良好的药代动力学效率。我们认为,这项研究为高效IDO1抑制剂的未来发展做出了巨大贡献,促进了结构多样性。
