I googled a bit, and found the following citation that says that fluconazole also impairs vacuolar acidification, like that drug in the Johns Hopkins study that you found, Sans Sucre.
Wondering what that Johns Hopkins study drug might be, I ran across the following citation -- it says something about synergy between azoles and amiodarone against candida, and amiodarone is a drug used to treat arrhythmia. I wonder if the mystery drug in the Johns Hopkins study is amiodarone.
Maybe someday they'll come up with a version of it that doesn't mess with healthy hearts, and only messes with the nasty candida! Sure hope so.
