Variotin (Pecilocin), an antifungal antibiotic, is produced by Paecilomyces varioti Bainer var. antibioticus and was isolated by Takeuchi et al. (1959). It is used topically for the treatment of human dermatomycosis.

Eberconazole is an antifungal drug with broad antimicrobial spectrum of activity. The drug was developed and approved in Spain (Ebernet 1% cream) for the treatment of tinea. Eberconazole exerts fungicidal or fungistatic activity depending on concentration, being fungicidal at higher concentration and fungistatic at lower concentrations. Eberconazole prevents fungal growth by inhibiting ergosterol synthesis, an essential component of the fungal cytoplasmic membrane leading to structural and functional changes. It prevents the fungal ergosterol synthesis by inhibiting lanosterol 14alpha-demethylase enzyme that is responsible for the formation of 14 alpha-methylsterols (precursor of ergosterols).

Pyrrolnitrin is an antifungal antibiotic and is most active against dermatophytic fungi, especially the species of Trichophyton. Fist, physical and chemical properties of pyrrolnitrin was described by Arima et al. It is synthesized from tryptophan, and the synthesis is probably initiated by a chloroperoxidase enzyme system acting on tryptophan. The present report deals with the mechanism of action of pyrrolnitrin. Pseudomonas pyrrocinia and other Pseudomonas species produce pyrrolnitrin from tryptophan as secondary metabolite. Pyrrolnitrin inhibits fungal growth by inhibiting the respiratory electron transport system.

Tolciclate [O-(1,2,3,4-tetrahydro-1,4-methanonaphthalen-6-yl)-m,N-dimethylthiocarbanilate] is an antimycotic agent with specific activity on dermatophytes. In vitro it is as active as tolnaftate, but shows greater liposolubility, which might be important for in vivo activity. When applied topically for 10 days to guinea pigs infected acutely with Trichophyton mentagrophytes (synonymous with T. asteroides), it is about three times more active than tolnaftate. Inhibition by tolciclate of sterol synthesis through blocking the step of squalene epoxidation in a fungal sterol biosynthetic pathway may be primarily involved in the antifungal action of the drug.

Diamthazole is an antifungal drug that was used for the treatment of tinea pedis. The drug was withdrawn from the market, because it was associated with neuropsychiatric adverse reactions.
