The resistance of pathogenic fungi and failure of drug therapy increased dramatically. Numerous studies have reported the individual or synergistic antifungal potency of natural and synthesized flavonoids, especially against drug-resistant fungi. This brief review summarizes the structure and individual or synergistic antifungal activity of natural and synthesized flavonoids (literatures mainly cover the past 10 years 2009-2019), with a special focus on the antifungal spectra, structure-activity relationship and mechanisms of actions. These may contribute to a better understanding of flavonoids as multi-target agents in the treatment of mycoses and provide some ideas on the development of novel flavonoids-based antifungals.
Keywords: Antifungal agents; Chalcones; Flavonoids; Mechanism of action; Structure-activity relationship; Synergy.
