我们鉴定并探索了一种新型的沙粒病毒细胞进入抑制剂的杂环化学系列的结构-活性关系(SAR)。优化的先导化合物,包括二苯基取代的咪唑并[1,2-a]吡啶类、苯并咪唑类和苯并三唑类,对假型和感染性旧世界和新世界沙粒病毒表现出低至亚纳摩尔的效力,在人和大多数非人肝微粒体中具有有吸引力的代谢稳定性,以及缺乏hERG K +通道或hERG酶抑制。此外,几种先导化合物(例如,咪唑并[1,2-a]吡啶的简单高产率3步合成可以提供一种成本有效的广谱沙粒病毒治疗剂,其可以帮助最小化与在经济困难的地理环境中治疗新出现的病毒相关的成本过高的负担。
We identified and explored the structure–activity relationship (SAR) of a novel heterocyclic chemical series of arenavirus cell entry inhibitors. Optimized lead compounds, including diphenyl-substituted imidazo[1,2-a]pyridines, benzimidazoles, and benzotriazoles exhibited low to sub-nanomolar potency against both pseudotyped and infectious Old and New World arenaviruses, attractive metabolic stability in human and most nonhuman liver microsomes as well as a lack of hERG K + channel or CYP enzyme inhibition. Moreover, the straightforward synthesis of several lead compounds (e.g., the simple high yield 3-step synthesis of imidazo[1,2-a]pyridine 37) could provide a cost-effective broad-spectrum arenavirus therapeutic that may help to minimize the cost-prohibitive burdens associated with treatments for emerging viruses in economically challenged geographical settings.
