Abstract

Here we designed and synthesized 58 deferasirox derivatives with the aim of discovering novel Antifungal agents. Most compounds exhibited moderate to excellent in vitro Antifungal activities against Cryptococcus neoformans H99 with MIC values ranging from 0.25 μg/mL to 16 μg/mL, including ten compounds with MIC values less than 1 μg/mL that were further screened against an additional six pathogenic fungi. This class of compounds showed high potency against Candida glabrata with MIC values ranging from <0.125 μg/mL to 1 μg/mL. We identified that compound 54 has high potency against 14 strains of Candida glabrata spp. and Cryptococcus spp. with MIC values ranging from <0.125 μg/mL to 1 μg/mL. In addition, compound 54 significantly reduced the CFU in a mouse model of disseminated Infection with Cryptococcus neoformans H99 at a dose of 10 mg/kg, which is comparable to FLC. Further investigations on compound 54 are currently in progress.
