Product Description
Mechanism of action
Caspofungin is an echinocandin antifungal that inhibits β‑(1,3)‑D‑glucan synthase, an essential enzyme for fungal cell‑wall glucan polymerisation. This weakens the fungal cell wall, causing osmotic fragility and lysis. It is fungicidal against *Candida* species and fungistatic against *Aspergillus* by inhibiting hyphal growth.
Benefits and advantages
Used in fungal‑cell‑wall biology, β‑glucan synthesis research, antifungal‑drug development, Aspergillus‑growth modelling, echinocandin SAR studies and resistance‑mechanism investigations.
Side effects and risks
Risks include infusion‑related reactions, hepatotoxicity, rash, histamine‑mediated flushing and mild GI symptoms. Handle under antifungal‑API safety protocols.
