Mechanism of action of Isavuconazonium

Isavuconazonium (eye" sa vue koe" na zoe' nee um) is a synthetic triazole and prodrug of isavuconazole, the active moiety. Similar to other triazoles, such as voriconazole and itraconazole, isavuconazole is believed to act through inhibition of the fungal 14a-ergosterol demethylase that is responsible for converting lanosterol to ergosterol, which blocks fungal cell membrane synthesis. Isavuconazonium has a broad spectrum of activity particularly against many aspergillus, candida and mucormycosis species.
