What is Cilofungin?

Plain description, key identifiers and synonyms

Cilofungin is a cyclic hexapeptide echinocandin antibiotic isolated from Aspergillus spp. By inhibiting the conversion of lanosterol to ergosterol, it invades a fungus' ability to synthesize cell walls. A modified form of echinocandin B, it is an antimycotic agent against Candida albicans. It has a role as an antiinfective agent. It is an echinocandin and an antibiotic antifungal drug.
