classified as the critical priority groups among the pathogenic fungi, highlighting the urgent need for developing more effective antifungal therapies. On the basis of antifungal natural product sampangine, herein, a series of tricyclicoxime and oxime ether derivatives were designed. Among them, compound WZ-2 showed excellent inhibitory activity against C. neoformans (MIC80 = 0.016 μg/mL) and synergized
新型隐球菌( C. neoformans )和白色念珠菌( C. albicans )被列为致病真菌中的重点群体,凸显了开发更有效的抗真菌疗法的迫切需要。在抗真菌天然产物sampangine的基础上,设计了一系列三环肟和肟醚衍生物。其中,化合物WZ-2对新型念珠菌表现出优异的抑制活性(MIC 80 = 0.016 μg/mL),并与氟康唑协同治疗耐药白色念珠菌(FICI = 0.078)。有趣的是,化合物WZ-2有效抑制毒力因子(例如荚膜、生物膜和酵母菌向菌丝的形态转变),表明其具有克服耐药性的潜力。在隐球菌性脑膜炎小鼠模型中,化合物WZ-2 (5mg/kg)有效降低了大脑新型隐球菌H99的负担。此外,化合物WZ-2单独使用以及与氟康唑联用也显着降低了白色念珠菌耐药株(0304103)和敏感株(SC5314)的肾脏负担。
