Indoleamine 2,3-dioxygenase 1 (IDO1) is regarded as a promising target for cancer immunotherapy. Many naphthoquinone derivatives have been reported as IDO1 inhibitors so far. Herein, two series of naphthoquinone derivatives, naphthoindolizine and indolizinoquinoline-5,12-dione derivatives, were synthesized and evaluated for their IDO1 inhibitory activity. Most of the target compounds showed significant
吲哚胺 2,3-双加氧酶 1 (IDO1) 被认为是癌症免疫治疗的一个有希望的靶点。迄今为止,许多萘醌衍生物已被报道为 IDO1 抑制剂。在此,合成了两个系列的萘醌衍生物,naphthoindolizine 和 indolizinoquinoline-5,12-dione 衍生物,并评估了它们的 IDO1 抑制活性。与色氨酸 2,3-双加氧酶 (TDO) 相比,大多数目标化合物对 IDO1 显示出显着的抑制效力和高选择性。还总结了构效关系。最有效的化合物5c(IC 50 23 nM,IDO1 酶)和5b'(IC 50 372 nM,HeLa 细胞)被鉴定为有前景的先导化合物。
