Honokiol, magnolol and its monoacetyl derivative show strong anti-fungal effect on <i>Fusarium</i> isolates of clinical relevance
The antifungal activity of magnolol and honokiol, two naturally occurring hydroxylated biphenyls, and of their synthetic derivatives was evaluated on a collection of representative isolates of <i>Fusarium oxysporum</i>, <i>F. solani</i> and <i>F. verticillioides</i&g...

| description |
The antifungal activity of magnolol and honokiol, two naturally occurring hydroxylated biphenyls, and of their synthetic derivatives was evaluated on a collection of representative isolates of <i>Fusarium oxysporum</i>, <i>F. solani</i> and <i>F. verticillioides</i> of clinical and ecological concern. The tested compounds were proposed as a ‘natural’ alternative to conventional fungicides, even though a larger range of concentrations (5–400 μg/ml) was applied. The activity of magnolol and honokiol was compared with that of terbinafine (0.1–10 μg/ml), and fluconazole (1–50 μg/ml), two fungicides widely used in treating fungal infections on humans. Magnolol showed similar fungicidal activity compared to fluconazole, whereas honokiol was more effective in inhibiting mycelium growth compared to this fungicide on all tested clinical <i>Fusarium</i> spp. isolates. Compared to terbinafine, honokiol showed similar antifungal activity when tested on clinical <i>F. solani</i> isolates, whereas magnolol was less effective at all selected concentrations (5–400 μg/ml). The different position of the phenol-OH group, as well as its protection, explain different <i>in vitro</i> activities between magnolol, honokiol, and their derivatives. Furthermore, magnolol showed mycelium dry weight reduction at a concentration of 0.5 mM when tested on a set of agricultural isolates of <i>Fusaria</i>, leading to complete inhibition of some of them. Magnolol and honokiol are proposed as efficient and safe candidates for treating clinically relevant <i>Fusaria</i>. |
