is a benzimidazole, imidazopyridine, benzofuran, benzothiophene, pyrimidine or benzene ring. When the [HetAr/Ar] unit is a 5,6-bicyclic heterocycle, it is oriented such that the 5-membered ring portion is connected to the [linker] unit and the 6-membered ring portion is connected to the [Am] unit. Among the 34 compounds in this series, compounds with benzofuran as the [HetAr/Ar] unit showed the highest
在此,我们描述了一种新型不对称三芳基双脒化合物系列[Am]-[吲哚]-[连接基]-[HetAr/Ar]-[Am]的合成和抗菌评价,其中[Am]是脒或氨基[连接体]为苯环、噻吩环或吡啶环,[HetAr/Ar]为苯并咪唑、咪唑并吡啶、苯并呋喃、苯并噻吩、嘧啶或苯环。[HetAr/Ar]单元为5,6-二环杂环时,其取向为5元环部分与[连接基]单元连接,6元环部分与[Am]连接。单元。在该系列的 34 种化合物中,以苯并呋喃为 [HetAr/Ar] 单元的化合物显示出最高的效力。在三芳基核心中引入氟原子或甲基会产生更有效的类似物。双脒对细菌更具活性,而单脒对哺乳动物细胞更活性(如低 CC 50值所示)。重要的是,我们发现化合物P12a (MBX 1887) 具有相对较窄的抗菌谱和非常高的 CC 50值。化合物P12a已扩大规模,目前正在接受进一步的治疗应用评估。
