Any oxo steroid that has an oxo substituent at position 11.
| Member | Definition | Role |
|---|
| 11-dehydrocorticosterone | An 11-oxo steroid that is corticosterone in which the hydroxy substituent at the 11beta position has been oxidised to give the corresponding ketone. | 11-dehydrocorticosterone |
| 11-ketotestosterone | A 3-oxo Delta(4)-steroid that is testosterone carrying an additional oxo substituent at position 11. | 11-oxotestosterone |
| 3alpha-hydroxy-4alpha-methylergosta-8,24(28)-dien-7,11-dione-26-oic acid | A steroid acid that is ergosta-8,24(28)-dien-26-oic acid substituted by a hydroxy group at position 3, a methyl group at position 4 and oxo groups at positions 7 and 11 (the 3alpha,4alpha,5alpha stereoisomer). Isolated from Antrodia cinnamomea and Antrodia camphorata, it exhibits cytotoxic, anticholinergic and antiserotonergic activities. | zhankuic acid B |
| 3alpha,12alpha-dihydroxy-4alpha-methylergosta-8,24(28)-dien-7,11-dione-26-oic acid | A steroid acid that is ergosta-8,24(28)-dien-26-oic acid substituted by hydroxy groups at positions 3 and 12, a methyl group at position 4 and oxo groups at positions 7 and 11 (the 3alpha,4alpha,5alpha,12alpha stereoisomer). Isolated from Antrodia cinnamomea and Antrodia camphorata, it exhibits antineoplastic activity. | zhankuic acid C |
| 4alpha-methylergosta-8,24(28)-dien-3,7,11-trione-26-oic acid | A steroid acid that is ergosta-8,24(28)-dien-26-oic acid substituted by a methyl group at position 4 and oxo groups at positions 3, 7 and 11 (the 4alpha,5alpha stereoisomer). Isolated from Antrodia cinnamomea and Antrodia camphorata, it exhibits cytotoxic and anti-inflammatory activity. | zhankuic acid A |
| adrenosterone | A 3-oxo Delta(4)-steroid that is androst-4-ene carrying three oxo-substituents at positions 3, 11 and 17. | adrenosterone |
| alphaxalone | | RU 5135 |
| cortisone | A C21-steroid that is pregn-4-ene substituted by hydroxy groups at positions 17 and 21 and oxo group at positions 3, 11 and 20. | cortisone |
| cucurbitacins | | Cucurbitacin S |
| nisone | | cortancyl |
| prednisone | A synthetic glucocorticoid drug that is particularly effective as an immunosuppressant, and affects virtually all of the immune system. Prednisone is a prodrug that is converted by the liver into prednisolone (a beta-hydroxy group instead of the oxo group at position 11), which is the active drug and also a steroid. | prednisone |
