NCIt definition : The sodium salt form of micafungin, a semi-synthetic echinocandin derived from a natural
product of the fungus Coleophoma empetri with antifungal activity. Micafungin, like
other cyclic lipopeptides, noncompetitively inhibits the fungal specific enzyme 1,3-beta-D-glucan
synthase, an enzyme essential for the synthesis of the important fungal cell wall
component 1,3-beta-D-glucan. By preventing the synthesis of 1,3-beta-D-glucan, the
cell wall is weakened which leads to osmotic lysis and eventually fungal cell death.;
