Abstract

Zwiebelane A (cis-2,3-dimethyl-5,6-dithiabicyclo[2.1.1]hexane 5-oxide), a natural product of onion bulbs (Allium cepa L.), is found to enhance the potential fungicidal activity of polymyxin B (PMB). As is the case with allicin, an allyl sulfur compound from garlic, zwiebelane A amplifies the disruptive effect of PMB on the vacuole of Saccharomyces cerevisiae, which has been found to represent a target for antifungal agents.
