|Description||Deflazacort (MDL 458) is a glucocorticoid used as an anti-inflammatory and immunosuppressant.|
|In vivo||Deflazacort results in a significant and equal decrease of thymus weight, indicating a marked reduction in total immunogenic tissue in rats.  Deflazacort reduces thymus weight and Daily weight gain in rats. Deflazacort lowers liver IFG-I and GHR mRNA in rats.  Deflazacort (DFC) is a heterocyclic glucocorticoid with anti-inflammatory activity but with decreased side effects. Deflazacort and [3H]dexamethasone (DEX) similarly induce in vivo ornithine decarboxylase activity in hippocampus and liver, although body weight loss after chronic treatment is significantly less for DFC.  Deflazacort induces dose-dependent decreases in osteocalcin (OC) plasma production rate (PPR). Deflazacort and prednisolone increase both postabsorptive plasma glucose and plasma calcium levels in sheep, but there are no significant differences between their effects.  Deflazacort, especially combined with L-arginine, spares quadriceps muscle from injury-induced regeneration (myf5 expression) compared with placebo treatment, despite an increase in membrane permeability immediately after exercise. Deflazacort alone prevents the typical progressive loss of function (measured as voluntary distance run over 24 hours) that is observed 3 months later in placebo-treated mice.  Deflazacort causes a less significant alteration in the pattern of GH secretion and does not negatively affect the overall amount of GH secreted. |

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
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.
