Description

Fluconazole (UK-49858) is a triazole antifungal agent with excellent activities against a broad range of fungi, especially against Candida albicans. Fluconazole inhibits C. albicans and Candida kefyr with IC99s range from 0.20 μg/mL to 0.39 μg/mL[1].

In Vitro

Fluconazole inhibits 4 species ofAspergillus fumigatus with the IC50s of 23.9-43.5 μg/mL. Fluconazole (0.20 μg/mL) inhibits significantly the mycelial-phase growth and germ tube elongation of C. albicans in a medium supplemented with serum[1].
Fluconazole is a triazole antifungal agent that has been available for the treatment of infections due to Candida, Cryptococcus. The MIC90 is highest for C. krusei (MIC ≥ 64 μg/mL) and C. glabrata (MIC, 32 μg/mL) and is ≤2 μg/mL for C. albicans (0.5 μg/mL), C. parapsilosis (2 μg/mL), C. tropicalis (2 μg/mL), C. lusitaniae (2 μg/mL), and C. kefyr (0.5 μg/mL)[2].
Fluconazole (0.1-50.0 μg/mL) damages the fungal cells and reduces their viability[3].

In Vivo

Fluconazole ( 0, 0.5, 1, 2.5, 5, 7.5, and 10 mg/kg; administered intraperitoneally (i.p.) as a single dose) results in a 50% reduction in fungal densities (ED50) of 4.87 mg/kg in a murine model of systemic candidiasis[4]. Fluconazole exhibits terminal elimination half-life of 2.4 h) following i.p. administration.The terminal half-life does not change with the dose of fluconazole administered[4].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (8.16 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (8.16 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
