Could Flavonoids Compete with Synthetic Azoles in Diminishing Candida albicans Infections? A Comparative Review Based on In Vitro Studies.

ABSTRACT

Flavonoids are polyphenolic compounds with already confirmed various health benefits. This review will shed light on flavonoids as potential antifungals in Candida albicans infections. C. albicans is an opportunistic pathogen able to cause serious health issues due to numerous virulence factors amplifying its pathogenicity. One of the most important virulence factors is Candida ability to form biofilms which are highly resistant to the treatment of antifungal drugs; making diminishing of this pathogen even more challenging. This review will focus on current knowledge on individual flavonoid compounds having the potential to deal with C. albicans in vitro, with special turn on antibiofilm potential and insight into the mode of action, where available. Majority of the commercial drugs for the treatment of candidiasis belong to azole class, so the activity of flavonoids will be compared with the activity of newly synthetized azole compounds, as well as with azole drugs that are already on the market as official therapeutics. This literature review will provide pros and cons for pushing future research towards exploring novel synthetic azoles or further examination of a wide pallet of natural flavonoids.
