Some observations were made on the anti-trichophyton action of 2-naphthyl N-methyl-N-arylthiocarbamate (A). In vitro antifungal activity decreased slightly when the thiocarbamate was changed to carbamate, and a marked lowering in the in vitro effect was observed. The antifungal activity disappeared entirely when the thiocarbamate was changed to dithiocarbamate and thiolcarbamate. When the aryl group in A is a naphthyl, antifungal activity is present only when 1-naphthyl is present and other three combinations are entirely ineffective. When the aryl is a substituted phenyl, compounds having methyl, methoxyl, or halogens, those with the Hammet constant in the range of +0.23 to -0.27, have marked antitrichophyton activity in vivo, but those with nitro, formyl, carboxyl, sulfonamido hydroxyl, or dimethylamino group show marked decrease in the effect. The series of compounds having the A type will henceforth be designated as naphthiomates.
