Fungal metal-dependent enzymes and cell membrane structures

Fungal metal-dependent enzymes and cell membrane structures represent a broad set of targets for certain antifungal agents, most notably ciclopirox [1]. These enzymes include various metalloenzymes such as cytochromes, catalases, and peroxidases that require polyvalent metal cations (e.g., Fe3+, Al3+) as essential cofactors for their catalytic activity [2]. By chelating these metal ions, drugs can disrupt fungal metabolism, nutrient uptake, and the degradation of toxic peroxides [1, 2]. Additionally, the interaction with these targets often leads to secondary damage to fungal cell membrane structures and mitochondrial function, resulting in a fungicidal or fungistatic effect [1]. This multi-targeted approach is particularly effective against a wide range of dermatophytes, yeasts, and molds, and is commonly utilized in the treatment of superficial fungal infections like onychomycosis and seborrheic dermatitis [2].
