Application

Isavuconazole has been used as an antifungal agent to test its effect on Mucor circinelloides gene transcription. It has also been used
to analyze its in vitro activity against isolates from the R. argillacea species complex A. fumigatus, N. hiratsukae and C. parapsilosis.

Biochem/physiol Actions

Isavuconazole is a triazole antifungal drug. It inhibits fungal sterol biosynthesis by inhibition of cytochrome P450 sterol 14-α-demethylase (CYP51), an enzyme in the sterol biosynthesis pathway that leads from lanosterol to ergosterol. It has been approved for the treatment of both invasive aspergillosis and invasive mucormycosis.

Isavuconazole, the active moiety of its prodrug isavuconazonium, is a new extended-spectrum triazole whose activity against yeasts, molds, including Aspergillus and mucorales, and dimorphic fungi has been shown in vitro and in preclinical models. The most relevant pharmacokinetics features are

Coinciding with the continually increasing population of immunocompromised patients worldwide, the incidence of invasive fungal infections has grown over the past 4 decades. Unfortunately, infections caused by both yeasts such as Candida and molds such as Aspergillus or Mucorales remain

Azole resistance is an emerging problem in Aspergillus fumigatus which translates into treatment failure. Alternative treatments with new azoles may improve therapeutic outcome in invasive aspergillosis (IA) even for strains with decreased susceptibility to current azoles. The in vivo efficacy
