Eighteen racemic 8.O.4'-neolignans with six different substitution patterns in rings A and B, in their ketone and in their erythro and three alcoholic forms, were evaluated for antifungal activity by the agar dilution method. Only the alcohols exhibited a broad spectrum of activities against Microsporum canis, Microsporum gypseum, Tricophyton mentagrophytes, Tricophyton rubrum, and Epidermophyton floccosum. (+/-)-erythro-3,4-(methylenedioxy)-7-hydroxy-1'-allyl-3'5'-dimethoxy-8.O.4'-neolignan (11) was the most active compound in the series, and E. floccosum was the most susceptible species.
