Anidulafungin is a semi-synthetic lipopeptide synthesized from a fermentation product of Aspergillus nidulans. Anidulafungin is an echinocandin, a class of antifungal drugs that inhibits the synthesis of 1,3-β-D-glucan, an essential component of fungal cell walls. Anidulafungin is active in vitro against many Candida, as well as some Aspergillus. Like other echinocandins, anidulafungin is not active against Cryptococcus neoformans, Trichosporon, Fusarium, or zygomycetes.
- Mechanism of action
Anidulafungin is a semi-synthetic echinocandin with antifungal activity. Anidulafungin inhibits glucan synthase, an enzyme present in fungal, but not mammalian cells. This results in inhibition of the formation of 1,3-β-D-glucan, an essential component of the fungal cell wall, ultimately leading to osmotic instability and cell death.
Target Actions Organism A1,3-beta-glucan synthase component FKS1inhibitor Aspergillus niger (strain CBS 513.88 / FGSC A1513)
- Volume of distribution
- 30 to 50 L
- Protein binding
Hepatic metabolism of anidulafungin has not been observed. Anidulafungin is not a clinically relevant substrate, inducer, or inhibitor of cytochrome P450 (CYP450) isoenzymes. Anidulafungin undergoes slow chemical degradation at physiologic temperature and pH to a ring-opened peptide that lacks antifungal activity.
- Route of elimination
Less than 1% of the administered radioactive dose was excreted in the urine. Anidulafungin is not hepatically metabolized.

During clinical trials a single 400 mg dose of anidulafungin was inadvertently administered as a loading dose. No clinical adverse events were reported. The maximum non-lethal dose of anidulafungin in rats was 50 mg/kg, a dose which is equivalent to 10 times the recommended daily dose for esophageal candidiasis (50mg/day).
