Description | Flucytosine (5-Fluorocytosine) is an antifungal drug with IC50 of 0.93 μM in C. albicans. |
---|---|
In vitro | Flucytosine inhibits the growth of C. neoformans in Sabouraud's dextrose broth at concentrations ≥ 1.25 mg/L, and Flucytosine of 50 mg/L causes a ~50% reduction in colony-forming unit (cfu)\ in the J774.16 killing assay with viability of J774.16 cells not affected measured by trypan blue exclusion. The combination of Flucytosine and IgGl monoclonal antibody to Cryptococcus neoformans capsular glucuronoxylomannan is more effective in reducing the numbers of C. neoformans colony-forming units in vitro with J774.16 murine macrophage-like cells than either agent alone. [2] The efficacy of Flucytosine (5FC) in combination with amphotericin B (AB) and fluconazole (FCZ) is studied against 35 yeast isolates, of which the 5FC-FCZ combination is antagonistic against Candida species, but for some Candida isolates synergism is found. [3] |
In vivo | Administration of Flucytosine in combination with monoclonal antibody 2H1 to A/JCr mice infected with C. neoformans significantly reduces lung but not brain cfu, which is more effective than either agent alone. [2] The combination of intravenous Flucytosine in 0.9% saline (NaCl) and amphotericin B (AmB) provides synergistic antifungal activity and is associated with a lower incidence of nephrotoxicity than with AmB treatment alone. Infusion of Flucytosine (5-10 mg/kg/min) dissolved in 5% glucose into the renal artery of an in situ perfused kidney for 15 minutes increases renal blood flow (RBF) in the rat, and the renal vasodilatation persists for the duration of the Flucytosine infusion.
