Micafungin is a semi-synthetic cyclic lipopeptide antifungal belonging to the echinocandin class that was reported in 1999 from Fujisawa in Japan. Unlike other marketed semi-synthetic derivatives in this class, Micafungin is derived from FR901379, which contains a phenolic sulfate to enhance aqueous solubility, a serious limitation in the echinocandin class.
Micafungin is soluble in ethanol, methanol, DMF or DMSO. It has moderate water solubility.
| Mechanism of Action | Micafungin inhibits the synthesis of β-(1,3)-D-glucan, an essential component of the cell wall of susceptible fungi. |
| Molecular Formula | C56H71N9O23S |
