Effects of pentachloronitrobenzene and some of its known and possible metabolites on fungi

Fungicidal activities of pentachloronitrobenzene and derivatives were tested with Candida albicans, Aspergillus fumigatus, Trichophyton rubrum, Trichophyton mentagrophytes, and Microsporon canis. In relation to pentachloronitrobenzene, no increasing fungistatic activities were found with cysteine derivatives. Rising fungistatic activities were seen with pentachlorophenylmethylsulfone and, in some of the strains, with pentachloronitrosobenzene, pentachlorothiophenol, pentachlorophenol, pentachloroaniline, pentachlorophenylmethylsulfoxide, the isomeric tetrachloronitrobenzenes, tetrachlorothiophenols, tetrachlorophenols, and tetrachloroanilines.
