Fosravuconazole L-lysine ethanolate Usage And Synthesis

Uses

Fosravuconazole L-lysine ethanolate (BMS-379224 L-lysine ethanolate), a proagent of Ravuconazole, is an orally active broad spectrum antifungal agent. Fosravuconazole L-lysine ethanolate can be used for candidiasis, onychomycosis and parasitemia research[1][2][3].

Biological Activity

Fosravuconazole L-lysine ethanolate (BMS-379224 L-lysine ethanolate), a prodrug of Ravuconazole, is an orally active broad-spectrum antifungal agent. Fosravuconazole L-lysine ethanolate can be used in the study of candidiasis, onychomycosis and parasitic diseases.

in vitro

Fosravuconazole has potent in vitro antifungal activity against a wide range of fungal species, including Candida , Aspergillus , and Trichophyton species .

in vivo

Fosravuconazole (E-1224; 10-50 mg/kg; oral administration; daily; for 20 days) treatment suppresses the parasitemia and prevents death in mice infected with the T. cruzi Y strain.

Animal Model: Swiss female mice (20-24 g) inoculated with trypomastigotes (Y strain).
Dosage: 10 mg/kg, 20 mg/kg, 30 mg/kg, 40 mg/kg , 50 mg/kg
Administration: Oral administration; daily; for 20 days
Result: Suppressed the parasitemia and prevented death.
