Sulbentine has a broad spectrum effect and is used especially in dermatomycoses treatment in the treatment of various forms.

2-(4-Chlorophenyl)ethanol is used as a pharmaceutical intermediate. It toxicity properties has been investigated both in rats after oral use and on rabbits after skin penetration.

Flutrimazole (trade names Flusporan, Funcenal, Micetal, Topiderm) is an imidazole derivative, a wide-spectrum antifungal drug used for the topical treatment of superficial mycoses of the skin. Flutrimazole interferes with the synthesis of ergosterol by inhibiting the activity of the enzyme lanosterol 14 α-demethylase. Flutrimazole’s antifungal activity has been demonstrated in in vivo and in vitro studies to be comparable to that of clotrimazole and higher than bifonazole. During clinical trials the incidence of adverse reactions in relation to the use of Flutrimazole skin cream was 8%, being the most frequent those described as slight burning, irritation, itching, and erythema in the area of application.

2,4,6-Tribromo-m-cresol (Tribromometacresol), an a hydroxytoluene, is an antifungal agent. It was used for the treatment of dermatomycoses.

Isoconazole is structurally related to miconazole and econazole and was synthesized by Janssen Pharmaceutica. The compound has been marketed in several countries, but not in the United States. It has broad-spectrum activity in vitro against dermatophytes, pathogenic yeasts, pathogenic filamentous fungi, gram-positive bacteria, and trichomonads . The mode of action appears to include rapid reduction in ATP concentrations caused by damage to the fungal cell membrane. Isoconazole interacted with the cell wall and caused convolutions and wrinkles. Isoconazole also inhibited the enzyme-catalyzed release of spheroplasts from young yeast cells. A recent study has demonstrated that application of the free base of isoconazole in combination with a volatile/nonvolatile vehicle, e.g., ethanol/propylene glycol, can increase drug bioavailability in the skin. This observation may lead to newer formulations of isoconazole and broaden its use for topical (e.g., spray) treatment of yeast and dermatophytic infections. Dermatophytic Isoconazole has been developed and marketed primarily as a once-a-day, topical anti-Candida agent for the treatment of vaginal candidiasis. Studies evaluating isoconazole have demonstrated that 80 to 90% of patients with vaginal candidiasis who were treated once a day with the drug remained clinically and mycologically cured. Following insertion of two 300-mg tablets, concentrations of isoconazole in the vagina remained above minimum inhibitory and minimum fungicidal levels for at least 72 h. Isoconazole has been developed and marketed primarily as a once-a-day, topical anti-Candida agent for the treatment of vaginal candidiasis. In clinical studies, very little of the drug entered the blood after a single vaginal application of a 600-mg dose; the same dose did not adversely affect intestinal flora by inducing a proliferation of yeast like species following prolonged administration. Studies evaluating demonstrated that 80 90% of patients.

Omoconazole is an azole antifungal drug, is used to treat candidiasis; dermatophytes and Pityriasis Versicolor

Fenticonazole is an imidazole derivative with a broad spectrum of antimycotic activity. It is used as a nitrate salt under different trade names (Lomexin, Gynoxin, Fentizol, etc) for the treatment of vaginal candidiasis. Fenticonazole inhibits the synthesis of ergosterol, an important step in the formation of the wall of fungi and blocks the oxidizing enzymes with the corresponding accumulation of peroxides and necrosis of the fungal cell. In vitro studies have shown a broad fungistatic and fungicidal activity. Like other azole agents, the spectrum of action of Fenticonazole also extends to some gram-positive bacteria such as Staphylococcus aureus. In vivo studies have also shown activity against Trichomonas Vaginalis.

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.
