Herein we report the first exploration of a dual‐targeting drug design strategy to improve the efficacy of small‐molecule cancer immunotherapy. New hybrids of indoleamine 2,3‐dioxygenase 1 (IDO1) inhibitors and DNA alkylating nitrogen mustards that respectively target IDO1 and DNA were rationally designed. As the first‐in‐class examples of such molecules, they were found to exhibit significantly enhanced anticancer activity in vitro and in vivo with low toxicity. This proof‐of‐concept study has established a critical step toward the development of a novel and effective immunotherapy for the treatment of cancers.

通过双重靶向IDO1和DNA提高癌症免疫疗法的效力

在此，我们报告了首次探索双重靶向药物设计策略以提高小分子癌症免疫疗法的功效。合理设计了吲哚胺2，3-二加氧酶1（IDO1）抑制剂和分别将IDO1和DNA分别靶向氮芥的DNA烷基化杂种。作为此类分子的首例，它们在体外和体内均显示出显着增强的抗癌活性，且毒性低。这项概念验证研究为开发新型有效的免疫疗法治疗癌症迈出了关键的一步。
