| aldosterone | A pregnane-based steroidal hormone produced by the outer-section (zona glomerulosa) of the adrenal cortex in the adrenal gland, and acts on the distal tubules and collecting ducts of the kidney to cause the conservation of sodium, secretion of potassium, increased water retention, and increased blood pressure. The overall effect of aldosterone is to increase reabsorption of ions and water in the kidney. | aldosterone |

| betamethasone valerate | A steroid ester that is betamethasone in which the hydroxy group at the 17alpha position has been converted to the corresponding pentanoate ester. | betamethasone valerate |
| corticosterone | A 21-hydroxy steroid that consists of pregn-4-ene substituted by hydroxy groups at positions 11 and 21 and oxo groups at positions 3 and 20. Corticosterone is a 21-carbon steroid hormone of the corticosteroid type produced in the cortex of the adrenal glands. | corticosterone |
| 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 |
| cortodoxone | A deoxycortisol that is cortisol in which the hydroxy group at position 11 has been replaced by a hydrogen. | 11-deoxycortisol |
| desonide | Triamcinolone acetonide with hydrogen instead of the fluorine substituent at position 9. A corticosteroid anti-inflammatory, it is used topically as a cream, ointment or lotion for the treatment of various skin disorders. | desonide |
| desoximetasone | Dexamethasone in which the hydroxy group at the 17alpha position is substituted by hydrogen. A synthetic corticosteroid with glucocorticoid activity, it is used as an anti-inflammatory and anti-pruritic in the treatment of various skin disorders, including skin allergies and psoriasis. | desoximetasone |
| desoxycorticosterone | A mineralocorticoid that is progesterone substituted at position 21 by a hydroxy group. | 11-deoxycorticosterone |
| diflorasone | The 16beta-analogue of flumethasone. It is used as the 17,21-diacetate as a topical anti-inflammatory and antipruritic in the treatment of various skin disorders. | diflorasone |
| dihydroxyacetone | A ketotriose consisting of acetone bearing hydroxy substituents at positions 1 and 3. The simplest member of the class of ketoses and the parent of the class of glycerones. | dihydroxyacetone |
| dihydroxyacetone phosphate | A member of the class of glycerone phosphates that consists of glycerone bearing a single phospho substituent. | dihydroxyacetone phosphate |
| epirubicin | An anthracycline that is the 4'-epi-isomer of doxorubicin. | 4'-epidoxorubicin |
| erythrulose | | erythrulose |
| flumethasone | | flumethasone |
| flunisolide | | flunisolide |
| fluocinolone acetonide | A fluorinated steroid that is flunisolide in which the hydrogen at position 9 is replaced by fluorine. A corticosteroid with glucocorticoid activity, it is used (both as the anhydrous form and as the dihydrate) in creams, gels and ointments for the treatment of various skin disorders. | fluocinolone acetonide |
| hydrocortisone valerate | | cortisol 17-valerate |
| hydrocortisone-17-butyrate | Cortisol esterified with butyric acid at the 17-hydroxy group. | cortisol 17-butyrate |
| hydroxydione | A 3-oxo-5beta-steroid formed from 11-deoxycorticosterone by reduction across the C4-C5 double bond. | 5beta-dihydrodeoxycorticosterone |
| hydroxypyruvic acid | A 2-oxo monocarboxylic acid that is pyruvic acid in which one of the methyl hydrogens is substituted by a hydroxy group. It is an intermediate involved in the glycine and serine metabolism. | 3-hydroxypyruvic acid |

| 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 |
