Small-molecule morphogenesis modulators enhance the ability of 14-helical β-peptides to prevent Candida albicans biofilm formation.

In this study we investigated the use of compounds that target C. albicans polymorphism, such as 1-dodecanol, isoamyl alcohol and farnesol, to attempt to improve β-peptide efficacy for preventing C. albicans biofilms. Isoamyl alcohol, which prevents hyphal formation, reduced the minimum biofilm prevention concentrations (MBPCs) of β-peptides by up to 128-fold. Combinations of isoamyl alcohol and antifungal β-peptides resulted in less than 10% hemolysis at the antifungal MBPCs. Overall, our results suggest potential benefits of combination therapies comprised of morphogenesis modulators and antifungal AMP peptidomimetics for preventing C. albicans biofilm formation.
