-demethylase. This enzyme is required to synthesize ergosterol, a vital component of the fungal cell membrane.
: Azoles inhibit the cytochrome P450-dependent enzyme lanosterol antifungal agent
: Blocking this enzyme leads to ergosterol depletion and the accumulation of toxic methylated sterols, ultimately altering membrane function and stopping growth. -demethylase
-(1,3)-D-glucan, a major polysaccharide responsible for maintaining the structural integrity of the cell wall, causing cell lysis. Common Examples : Terbinafine
To combat fungal infections safely, medical science targets biological structures and pathways that are unique to fungi. Modern antifungal agents are primarily categorized into four major classes based on their specific mechanisms:
: This blocks an early step in ergosterol biosynthesis, leading to a toxic buildup of squalene and depletion of ergosterol. Common Examples : Terbinafine. Antifungal Agents - StatPearls - NCBI Bookshelf - NIH
: Caspofungin , micafungin, and anidulafungin. 4. Allylamines
