Isavuconazole is an active form of isavuconazonium, a prodrug which is marketed under the name Cresemba. Isavuconazole inhibits lanosterol 14-alpha demethylase (or CYP51A1) and leads to the accumulation of ergosterol toxic precursors in the fungal cytoplasm. Isavuconazole is indicated for the treatment of invasive aspergillosis and invasive mucormycosis.

Isavuconazole exhibited MIC50 values of 1–4 ug/ mL and MIC90 values of 4–16 ug/mL, against Mucorales isolates. MIC90 against Aspergillus fumigatus was 0.5–2 ug/ml, MIC90 against Aspergillus terreus was 0.5–4 ug/ml, MIC90 against Aspergillus flavus was 1–16 ug/ml, MIC90 against Aspergillus niger was 2–4 ug/ml.
