ABSTRACT
Herein, we report the design, synthesis and evaluation of a novel series of diselenide and selenide derivatives as potent antifungal agents by exploiting the hydrophobic cleft of CYP51. Among all synthesized compounds, the most potent compound B01 with low cytotoxic and hemolysis effect exhibited excellent activity against C.alb., C.gla., C.par. and C.kru., as well as selected fluconazole-resistant strains. Moreover, compound B01 could reduce the biofilm formation of the FCZ-resistant C.alb. Subsequently, metabolic stability assays using liver microsomes demonstrated that compound B01 showed good profiles of metabolic stability. With superior pharmacological profile, compound B01 was advanced into in vivo bioactivity evaluation. In a murine model of systemic C.alb. infection, compound B01 significantly reduced fungal load of kidneys. Furthermore, compound B01 revealed relatively low acute toxicity and subacute toxicity in mice. In addition, docking study performed into C.alb. CYP51, showed the binding mode between C.alb. CYP51 and compound B01. Collectively, diselenides compound B01 can be further developed for the potential treatment of invasive fungal infections.
