Deflazacort (ML-458; ML458; DL-458-IT, L-5458; Cortax; Decortil; Deflanil; Flezacor; trade name: Emflaza) is a potent glucocorticoid drug approved for use as an anti-inflammatory and immunosuppressant. It was approved by FDA in 2017 to treat patients age 5 years and older with Duchenne muscular dystrophy (DMD). Deflazacort is an inactive prodrug which is metabolized rapidly to the active drug 21-desacetyldeflazacort. 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.
| ln Vitro |
The inert prodrug deflazacort quickly transforms into the active metabolite 21-desacetyldeflazacort. After 1.3 hours, maximum 21-desacetyldeflazacort concentrations were measured, with an average of 116 ng/ml. The terminal half-life was 1.3 hours, and the average area under the curve was 280 ng/ml.h. Prednisolone and methylprednisolone were eliminated considerably slower than 21-desacetyldeflazacort[1].

*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.
