Anti-Candida property of a lignan glycoside derived from Styrax japonica S. et Z. via membrane-active mechanisms.

Styraxjaponoside C was investigated with respect to its antifungal activity and mechanisms of action. Devoid of hemolytic activity, Styraxjaponoside C demonstrated an antifungal effect against the human pathogenic yeast Candida albicans in an energy-independent manner. To characterize the mechanisms of the antifungal activity of Styraxjaponoside C, fluorescence analysis with membrane probe 1,6-diphenyl-1,3,5-hexatriene, and flow cytometric analysis on C. albicans were conducted. The results showed that Styraxjaponosdie C induced cytoplasmic membrane perturbation. The current study suggested that Styraxjaponoside C was active against C. albicans with membrane-active mechanisms.
