      Ciclopirox (Penlac) is a synthetic antifungal agent.;Target: AntifungalCiclopirox is a synthetic antifungal agent for topical dermatologic treatment of superficial mycoses. It is most useful against Tinea versicolor. The mechanism of action of ciclopirox is poorly understood [1]. However, loss of function of certain catalase and peroxidase enzymes has been implicated as the mechanism of action, as well as various other components of cellular metabolism. In a study conducted to further elucidate ciclopirox's mechanism, several Saccharomyces cerevisiae mutants were screened and tested. Results from interpretation of the effects of both the drug treatment and mutation suggested that ciclopirox may exert its effect by disrupting DNA repair, cell division signals and structures (mitotic spindles) as well as some elements of intracellular transport [2]. It acts by inhibiting the membrane transfer system by interrupting the Na+ K+ ATPase [1]. It is currently being investigated as an alter MedChem Express HY-B0450
