caryophyllene and sulconazole

Caryophyllene oxide, an oxygenated terpenoid, well known as preservative in food, drugs and cosmetics, has been tested in vitro as an antifungal against dermatophytes. Its antifungal activity has been compared to ciclopiroxolamine and sulconazole, commonly used in onychomycosis treatment and chosen because of their very different chemical structures. So, a new model has been tested, utilizing sheep hoof plates in order to simulate human nails, which are almost unobtainable for in vitro tests. Three protocols were utilized: pre-treatment, simultaneous treatment and post-treatment. Among these, the post-treatment method was the best to simulate antifungal therapy, as it permitted testing and comparing the efficiency of different antifungal drugs.
