Glucan synthase inhibitor
Beta-glucan synthase inhibitor
- ↓ beta-1,3-glucan synthesis → weakens the fungal cell wall
- Fungicidal for Candida, fungistatic for Aspergillus
- No human counterpart to the target → notably clean
Drugs with this mechanism (2)
- Caspofungin — IV echinocandin for invasive candidiasis; glucan-synthase blocker with little renal toxicity.
- Micafungin — Echinocandin blocking fungal glucan synthesis; no human target equivalent.
Self-check
- Is glucan-synthase inhibition fungicidal against Candida?
Yes. - Is it fungicidal or fungistatic against Aspergillus?
Fungistatic.
