order to take advantage of both immunotherapeutic and epigenetic antitumor agents, the first generation of dual indoleamine 2,3-dioxygenase 1 (IDO1) and histone deacetylase (HDAC) inhibitors were designed. The highly active dual inhibitor 10 showed excellent and balanced activity against both IDO1 (IC50 = 69.0 nM) and HDAC1 (IC50 = 66.5 nM), whose dual targeting mechanisms were validated in cancer cells
为了同时利用免疫治疗和表观遗传抗肿瘤药,设计了第一代双吲哚胺2,3-二加氧酶1(IDO1)和组蛋白脱乙酰基酶(HDAC)抑制剂。高活性双重抑制剂10对IDO1(IC50 = 69.0 nM)和HDAC1(IC50 = 66.5 nM)均显示出优异且平衡的活性,其双重靶向机制已在癌细胞中得到验证。化合物10作为口服活性抗肿瘤药具有良好的药代动力学特征,并显着降低了血浆中的鸟尿素水平。特别地,它在鼠LLC肿瘤模型中显示出优异的体内抗肿瘤功效,且毒性低。这项概念验证研究为癌症治疗提供了一种新颖的策略。
