Abstract
ABSTRACTAn urgent need exists for new antifungal compounds to treat fungal infections in immunocompromised patients. The aim of the current study was to investigate the potency of a novel antifungal compound, MYC-053, against the emerging yeast and yeast-like pathogens Candida glabrata, Candida auris, Cryptococcus neoformans, and Pneumocystis spp. MYC-053 was equally effective against the susceptible control strains, clinical isolates, and resistant strains, with the minimum inhibitory concentrations (MIC) of 0.125–4.0 μg/mL. Notably, unlike other antifungal compounds, MYC-053 was effective against Pneumocystis isolates. MYC-053 was highly effective against preformed 48-h-old yeast biofilms, with the minimal biofilm eradication concentrations equal to 1–4 times MIC. The compound was not cytotoxic against L2 and A549 cell lines at concentrations over 100 μg/ml. Further, it possessed no apparent hemolytic activity up to 1000 μg/ml (the highest concentration tested). Overall, these data indicated that MYC-053 has a broad therapeutic window and may be developed into a promising antifungal agent for the treatment and prevention of invasive fungal infections caused by yeasts and yeast-like fungi in neutropenic patients.
