: Allylamines inhibit the enzyme squalene epoxidase.
: Caspofungin , micafungin, and anidulafungin. 4. Allylamines
-demethylase. This enzyme is required to synthesize ergosterol, a vital component of the fungal cell membrane. antifungal agent
: This binding creates physical pores or channels in the membrane. Small essential molecules and cellular organelles leak out of these pores, causing cell death. Common Examples : Amphotericin B, nystatin , and natamycin. 3. Echinocandins
: 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 : Allylamines inhibit the enzyme squalene epoxidase
: Polyene drugs act directly on the fungal cell membrane by binding to ergosterol.
: Blocking this enzyme leads to ergosterol depletion and the accumulation of toxic methylated sterols, ultimately altering membrane function and stopping growth. Allylamines -demethylase
: This class targets the fungal cell wall rather than the membrane. They inhibit the enzyme -(1,3)-D-glucan synthase. Effect : This blocks the synthesis of
