Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/10857570
Curator's Comment: Note: there is a lot of confusion in the literature about the structure of methylprednisolone vs methylprednisone. Methylprednisolone has OH group at 11th position, whereas methylprednisone has carbonyl (=O) group. In most reported clinical trials where authors reference methylprednisone, methylprednisolone was investigated. See for example https://www.ncbi.nlm.nih.gov/pubmed/12201245

11-keto methylprednisolone is a metabolite of corticosteroid immunosuppressant methylprednisolone.
