occasioned the need for new antifungal agents. Herein, we report the synthesis of 27 new FLC derivatives along with their antifungal activity against a panel of 13 clinically relevant fungal strains. We also explore their toxicity against mammalian cells, their hemolytic activity, as well as their mechanism of action. Overall, many of our FLC derivatives exhibited broad-spectrum antifungal activity and all compounds

azole-resistant fungi. The fungistatic nature of FLC in combination with toxicity concerns have resulted in an increased demand for new azole antifungal agents. Herein, we report the synthesis and antifungal activity of novel alkylated piperazines and alkylated piperazine-azole hybrids, their time-kill studies, their hemolytic activity against murine erythrocytes, as well as their cytotoxicity against mammalian
Compounds and compositions having antifungal activity, and methods of using the antifungal compounds and compositions, are described for use in treating fungal infections.

Design, synthesis and biological activity of hybrid antifungals derived from fluconazole and mebendazole
5-benzoylbenzimidazole scaffold showed better antifungal activity against Candida spp. and Cryptococcus neoformans than related benzimidazole and benzothiazole derivatives. The better results were obtained with the 4-chloro derivative 4b displaying MICs <0.063–1 μg/mL. Although, removing benzoyl group from compound 4b had negative effect on the activity, optimization of phenethyl-triazole scaffold by desired
设计并合成了一系列带有 5-苯甲酰基苯并咪唑-2-基硫基侧链的新型三唑醇抗真菌剂,作为氟康唑(一种典型的三唑类抗真菌剂)和甲苯咪唑(一种具有抗真菌活性的驱虫剂)的混合物。通过合适的环氧乙烷和所需的 2-巯基苯并咪唑的反应合成标题化合物。尽管有可能形成不同的N取代或S取代的产物,但最终化合物的结构通过使用13指定为硫醚同系物C核磁共振光谱。主要先导化合物(A 系列)的 SAR 分析是通过将 5-苯甲酰基苯并咪唑-2-基硫基残基简化为苯并咪唑-2-基硫基(B 系列)或苯并噻唑-2-基硫基侧链(C 系列)进行的,并且苯乙基-三唑支架上卤素取代基的修饰。一般来说,含有 5-苯甲酰苯并咪唑支架的A 系列(化合物4a-e )对念珠菌属表现出更好的抗真菌活性。和新型隐球菌比相关的苯并咪唑和苯并噻唑衍生物。使用显示 MIC <0.063–1 μg/mL 的4-氯衍生物4b获得了更好的结果。虽然,从化合物4
