Ontology: ciclopirox (C0055711)

Definition (NCI) A synthetic, broad-spectrum antifungal agent with additional antibacterial and anti-inflammatory activities. Ciclopirox exerts its action by binding to and chelating trivalent cations, such as Fe3+ and Al3+, thereby inhibiting the availability of essential co-factors for enzymes. This may lead to a loss of activity of enzymes that are essential for cellular metabolism, organization of cell wall structure and other crucial cell functions. In addition, ciclopirox exerts its anti-inflammatory activity by inhibiting 5-lipoxygenase and cyclooxygenase (COX).
