Application

Dexamethasone 21-phosphate disodium salt has been used:
  • as a positive control to study its effects on ocular shedding of herpes simplex virus type 1 (HSV-1) in the induced reactivation (IR) and spontaneous shedding (SS) rabbit models[1]
  • as a receptor analog to study its effects on glucocorticoid receptor activation in suprachiasmatic nuclei (SCN)-lesioned mice[2]
  • to study its protective effects against cisplatin-induced ototoxicity in the inner ear of guinea pigs[3]

Biochem/physiol Actions

Dexamethasone 21-phosphate (Dex 21-P) is a pro-drug[4] that can undergo dephosphorylation to form dexamethasone with the help of intra-erythrocyte enzymes.[5] It exhibits therapeutic effects against cystic fibrosis[4] and postoperative cataract.[6] Dex 21-P disodium salt is a synthetic adrenal corticosteroid and possesses anti-inflammatory activity.[6]

Questions

  1. We planned to dissolve it into saline and use to to inject as prenatal stressor to Sprague-Dawley rats via IP way. What is the solubility? I want to dissolve 100µg and 200µg into 10ml of saline. After dissolving what is the shelf life of that solution?

    1 answer
    1. The solubility of this produst is tested in water at 50 mg/mL The solubility in saline has not been tested, however rates are expected to be similar. The solution stability has not been determined. Other sources state that solutions are stable for up to 1 month when stored in aliquots at -20°C.
