fungal infections (IFIs), effective and safe antifungal agents are rather limited. Starting from antifungal lead compound haloperidol that was identified by drug repurposing, a series of novel benzocyclane derivatives were designed, synthesized, and assayed. Several compounds showed improved antifungal potency and broader antifungal spectra. Particularly, compound B10 showed good inhibitory activities against
尽管侵入性真菌感染(IFI)的发病率和死亡率很高,但是有效和安全的抗真菌剂仍然受到限制。从通过药物再利用确定的抗真菌先导化合物氟哌啶醇开始,设计,合成和分析了一系列新型苯并环烷衍生物。几种化合物显示出提高的抗真菌效力和更宽的抗真菌谱。特别地,化合物B10显示出对多种真菌病原体的良好抑制活性,并且被证明是对药物抗性重要的几种毒力因子的抑制剂。在体内隐球菌病和念珠菌病模型中,化合物B10可以有效减轻新型隐球菌的脑真菌负担,并与氟康唑协同治疗耐药性白色念珠菌感染。初步的抗真菌机制研究表明,与氟康唑联合使用时,化合物B10恢复了细胞膜损伤并下调了ERG11和MDR1基因的过表达。总之,氟哌啶醇衍生物B10是开发新一代抗真菌剂的有前途的先导化合物。
