Voriconazole (UK-109496; UK109496; trade name Vfend) is a 2nd-generation and potent triazole-based antifungal drug used for treating a variety of fungal infections. It is structurally similar to fluconazole and itraconazole that acts by inhibiting fungal cytochrome P-450-dependent, 14-alpha-sterol demethylase-mediated synthesis of ergosterol.
ln Vitro |
Strong action is shown by voriconazole against S. Apiospermum and C. neoformans, with 0.125-0.25 μg/mL and 0.5 μg/mL, respectively, as MICs[1]. The cytochrome P450 (CYP)-dependent enzyme 14-alpha-sterol demethylase is inhibited by voriconazole, which damages cell membranes and stops the growth of fungi [2].

ln Vivo |
In a dose-dependent manner, voriconazole (5–20 mg/kg; orally for 21 days) extends survival. In the lungs, voriconazole (40 mg/kg/day) reduces the amount of fungal growth [3].

Animal Protocol |
Animal/Disease Models: Male specific-pathogen-free BALB/cByJ mice[3]
Doses: 1, 5, 20 mg/kg/day Route of Administration: Po one time/day for 21 days Experimental Results: Improved survival in a dose-response fashion, with median survival times (MSTs) of 21, 28, and 35 days with doses of 1, 5, and 20 mg/kg, respectively. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
