Indoleamine 2,3-dioxygenase 1 (IDO1) is an attractive target for anticancer therapy. Herein, we report a virtual screening study which led to the identification of compound 5 as a new IDO1 inhibitor. In order to improve the biological activity of the identified hit, arylthioindoles 6–30 were synthesized and tested. Among these, derivative 21 exhibited an IC50 value of 7 μM, being the most active compound
吲哚胺 2,3-双加氧酶 1 (IDO1) 是抗癌治疗的一个有吸引力的目标。在此,我们报告了一项虚拟筛选研究,该研究导致将化合物5鉴定为新的 IDO1 抑制剂。为了提高所识别命中的生物活性,arylthioindoles 6 - 30合成并测试。其中,衍生物21的IC 50值为7 μM,是该系列中活性最强的化合物。此外,化合物5和21诱导表达 IDO1 的癌细胞系 HTC116 和 HT29 的剂量依赖性生长抑制。为了使获得的结果合理化并提出新的化学修饰,进行了三维定量构效关系研究。
