A series of thiosulfonates have been prepared and tested against Aspergillu
s niger and Aspergillus flavus. In general, the thiosulfonates are moderate
antifungal agents-more potent than corresponding inactive disulfides and l
ess potent than corresponding very active fungitoxic disulfides. A pair of
thiosulfonates show high selectivity, each killing only one kind of fungus.
