N-Desalkyl-itraconazole is believed to exert its effects through the inhibition of ergosterol synthesis, an essential component of fungal cell membranes. Ergosterol plays a vital role in maintaining the integrity and proper functioning of fungal cell membranes. By impeding its synthesis, N-Desalkyl-itraconazole disrupts the structure and function of the cell membrane, ultimately leading to the demise of the fungus. Notably, it has exhibited notable efficacy as an inhibitor of Candida albicans, a prevalent causative agent of fungal infections. Moreover, its potential applications extend to the treatment of other fungal infections caused by species such as Aspergillus and Cryptococcus. This application highlights its potential to combat fungal contamination and ensure the safety and longevity of food products. Additionally, its insecticidal properties have been explored, suggesting potential applications as an insecticide.
