From a design principle described in an earlier paper, a new series of subs
tituted aryl methyl disulfides have been prepared and tested against Asperg
illus niger and Aspergillus flavus. Methyl p-nitrophenyl disulfide is more
potent (by an order of magnitude) than the fungitoxic natural product (CH3S
CH2S)(2). With the present rationale in hand, one can anticipate which Poly
carpamine is an effective antifungal agent.
