Abstract

Inhibition of indoleamine 2,3-dioxygenase (IDO1) is an attractive immunotherapeutic approach for the treatment of a variety of cancers. Dysregulation of this enzyme has also been implicated in other disorders including Alzheimer's disease and arthritis. Herein, we report the structure-based design of two related series of molecules: 1-substituted 5-indoleimidazoles and 1-substituted 5-phenylimidazoles. The latter (and more potent) series was accessed through an unexpected rearrangement of an imine intermediate during a Van Leusen imidazole synthesis reaction. Evidence for the binding modes for both inhibitor series is supported by computational and structure-activity relationship studies.

摘要

抑制吲哚胺2,3-双加氧酶(IDO1)是一种有吸引力的免疫治疗方法,可用于治疗多种癌症。该酶的失调也与包括阿尔茨海默病和关节炎在内的其他疾病有关。在此,我们报告了两个相关系列分子的基于结构的设计:1-取代的5-吲哚咪唑和1-取代的5-苯基咪唑。后一个(且更具活性)系列是通过Van Leusen咪唑合成反应中亚胺中间体的意外重排得到的。计算和构效关系研究支持了这两个抑制剂系列的结合模式的证据。
