Voriconazole increases the osteogenic activity of human osteoblasts in vitro. Osteoblasts were exposed to voriconazole (VCZ) or fluconazole (FCZ) at 15 or 200 μg/ml in osteoinductive medium (OS+) for up to 7 days. As a positive control, cells were also exposed to sodium fluoride (NaF) at 10 μM in nonosteoinductive medium (OS−). Osteoblastic differentiation was evaluated by measuring alkaline phosphatase (ALP) activity (A) and staining for calcium deposition with alazarin red S stain (B and C); calcium deposition was quantified by measuring the absorbance (A415) of extracted alazarin red S (B) and was assessed by the light microscopic appearance (white arrows) of stained osteoblast cultures (C). Values represent the means ± SD. *, P < 0.05, compared to osteoblasts grown under osteogenic conditions without treatment.

| In vitro |
Voriconazole is active against certain opportunistic filamentous and dimorphic fungi (molds) and yeasts. Voriconazole in vitro activities are higher than or similar to those of itraconazole and amphotericin B for most of the molds tested, with the exceptions of R. arrhizus and S. schenckii. [1] Voriconazole inhibits 95% of isolates at ≤1 μg/ml against 448 recent clinical mold isolates. [2] |

| In vivo | Voriconazole is significantly more effective than itraconazole in reducing Aspergillus content in the lungs of immunocompromised guinea pig with pulmonary aspergillosis. Voriconazole also has been shown to be effective in guinea pigs with experimental pulmonary or intracranial infections caused by C. neoformans. [1] Voriconazole (5 mg/kg/day, i.p.) combined with Amphotericin B (1.25 mg/kg/day, i.p.) significantly reduces the colony counts in the tissues of selected Guinea pigs compared with those in the tissues of the controls. Voriconazole (5 mg/kg/day, i.p.) combined with Amphotericin B (1.25 mg/kg/day, i.p.) also results in reductions in colony counts in tissues compared with those in the tissues of Guinea pigs treated with caspofungin acetate (the difference is not statistically significant) and improves the survival times but does not sterilize tissues. Voriconazole (5 mg/kg/day, i.p.) combined with caspofungin acetate (CAS) at either dose reduces colony counts in tissues 1,000-fold over those for the controls and are the only regimens that significantly reduces the numbers of positive cultures.

Bio Calculators
Molarity Calculator
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).
Dilution Calculator
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.

Question 1:
I am trying to use voriconazole in vivo via ip injection. Is the formulation recommended on your website (2% DMSO+30% PEG 300+2% Tween 80+ddH2O) suitable for injection?
-
Answer:
S1442 can be dissolved in 2% DMSO+30% PEG 300+2% Tween 80+ddH2O at 8mg/ml clearly. When making the solution, please dissolve the compound in DMSO clearly first. Then add PEG and Tween, after they mixed well, then dilute with water.
