Antifungal Agent Review
-(1,3)-D-glucan, a major polysaccharide responsible for maintaining the structural integrity of the cell wall, causing cell lysis.
: Fluconazole , itraconazole , and voriconazole . 2. Polyenes
: 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
: Blocking this enzyme leads to ergosterol depletion and the accumulation of toxic methylated sterols, ultimately altering membrane function and stopping growth.
Fungi are eukaryotic organisms found in nearly every environment. While most are harmless, a specific subset can cause human diseases ranging from mild skin conditions to life-threatening systemic infections. Because both humans and fungi are eukaryotes, they share similar cellular and molecular processes. This biological similarity makes it exceptionally challenging to develop drugs that selectively eliminate fungal pathogens without causing toxicity to the human host. 🎯 Primary Classes and Mechanisms of Action
: Caspofungin , micafungin, and anidulafungin. 4. Allylamines
: Allylamines inhibit the enzyme squalene epoxidase.
-demethylase. This enzyme is required to synthesize ergosterol, a vital component of the fungal cell membrane.
