|Description||Fluconazole is a fungal lanosterol 14 alpha-demethylase inhibitor, which thereby prevents the formation of ergosterol,used in the treatment and prevention of superficial and systemic fungal infections.|
Fluconazole in combination with amphotericin B (AmB) has a synergistic effect on C. albicans planktonic cells but does not alter AmB activity against biofilms. Fluconazole and caspofungin have an antagonistic effect against biofilms but not with planktonic cells. Fluconazole-mediated membrane perturbation (due to inhibition of ergosterol biosynthesis) increases calcineurin inhibitor intracellular concentrations. Fluconazole treatment significantly reduces levels of ergosterol within the cell in C. albicans planktonic cells, leading to cell membrane perturbation.  Fluconazole activity is less sensitive to acidic medium than is that of ketoconazole. Fluconazole is approximately 16-fold less active than ketoconazole against 35 representative isolates of C. albicans at physiologic pH.  Fluvastatin, a cholesterol-lowering drug, exhibits minimal activity (MICs of 64 to >128 mg/mL) against Candida species and Cryptococcus neoformans. Fluconazole combined with itraconazole exhibits potent activities against C. albicans, C. tropicalis, C. parapsilosis, and C. neoformans, including flucon- azole-resistant strains of C. albicans and C. tropicalis. 
|In vivo||Fluconazole is very effective in prolonging survival of rats infected with a representative candidal strain.  Fluconazole has a dramatic effect on the fungicidal activity of flucytosine in murine cryptococcal meningitis. Fluconazole combined with flucytosine and amphotericin B have significantly improved activity against cryptococcal meningitis compared with the activity of each drug used alone. |

|In vitro||DMSO||61 mg/mL (199.17 mM)|
|Ethanol||61 mg/mL (199.17 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
2% DMSO+30% PEG 300+2% Tween 80+ddH2O
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
