  • 21-Desacetyldeflazacort (21-desDFZ) is the active metabolite of Deflazacort (HY-13609). Deflazacort is an anti-inflammatory and immunosuppressant. Deflazacort is an inactive pro-drug which can be rapidly converted by esterases to the active metabolite 21-desacetyldeflazacort after oral administration[1].
