  新型不对称三芳基双脒化合物的合成及抗菌评价

  摘要：

  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。

• Synthesis and antifungal evaluation of head-to-head and head-to-tail bisamidine compounds

  Herein, we describe the antifungal evaluation of 43 bisamidine compounds, of which 26 are new, having the scaffold [Am]-[HetAr]-[linker]-[HetAr]-[Am], in which [Am] is a cyclic or acyclic amidine group, [linker] is a benzene, pyridine, pyrimidine, pyrazine ring, or an aliphatic chain of two to four carbon, and [HetAr] is a 5,6-bicyclic heterocycle such as indole, benzimidazole, imidazopyridine, benzofuran, or benzothiophene. In the head-to-head series the two [HetAr] units are oriented such that the 5-membered rings are connected through the linker, and in the head-to-tail series, one of the [HetAr] systems is connected through the 6-membered ring; additionally, in some of the head-to-tail compounds, the [linker] is omitted. Many of these compounds exhibited significant antifungal activity against Candida albicans, Candida krusei, Candida glabrata, Candida parapsilosis, and Cryptococcus neoformans (MIC <= 4 mu g/ml). The most potent compounds, for example, P10, P19 and P34, are comparable in antifungal activities to amphotericin B (MIC 0.125 mu g/ml). They exhibited rapid fungicidal activity (>3 log(10) decrease in cfu/ml in 4 h) at concentrations equivalent to 4x the MIC in time kill experiments. The bisamidines strongly inhibited DNA, RNA and cell wall biosynthesis in C. albicans in macromolecular synthesis assays. However, the half-maximal inhibitory concentration for DNA synthesis was approximately 30-fold lower than those for RNA and cell wall biosynthesis. Fluorescence microscopy of intact cells of C. albicans treated with a bisamidine exhibited enhanced fluorescence in the presence of DNA, demonstrating that the bisamidine was localized to the nucleus. The results of this study show that bisamidines are potent antifungal agents with rapid fungicidal activity, which is likely to be the result of their DNA-binding activity. Although it was difficult to obtain a broad-spectrum antifungal compound with low cytotoxicity, some of the compounds (e.g., P9, P14 and P43) exhibited favorable CC50 values against HeLa cells and maintained considerable antifungal activity.

  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
