Epiestradiol is an estradiol isomer with weak estrogenic activity.

Gestodene (17alpa-ethynyl-13beta-ethyl-17beta-hydroxy-4,15-gonadien-3-one) is the most potent synthetic progestin currently available and it is widely used as a fertility regulating agent in a number of contraceptive formulations because of its high effectiveness, safety and acceptability. Products containing gestoden include Meliane, which contains 20 ug of ethinylestradiol and 75 ug of gestodene; and Gynera, which contains 30 ug of ethinylestradiol and 75 ug of gestodene. Gestodene is androgenically neutral, meaning that contraceptive pills containing gestodene do not exhibit the androgenic side effects (e.g. acne, hirsutism, weight gain) often associated with second-generation contraceptive pills. Gestodene displays a high binding affinity to the progesterone receptor, also binds to adrogen and glucocorticoid receptors but no measurable affinity for the estrogen receptor.

Norgestomet is a synthetic derivative of progesterone with improved oral activity due to its 17α-acetate side chain. In veterinary medicine norgestomet is used for the synchronisation of oestrus in cattle. It is administered as a subcutaneous ear implant (containing 3 mg norgestomet; to be removed after 9 to 10 days), in combination with a single intramuscular injection containing 3 mg norgestomet and 5 mg oestradiol valerate. The injection is to be given immediately after application of the implant. Norgestomet is not used in human medicine. It is a steroidal progestin of the 19-norprogesterone group.

Diflucortolone (used in the form of valerate prodrug) is a corticosteroid developed for the treatment of inflammatory skin diseases. It is supposed that Diflucortolone acts by inducing Annexin A1, a phospholipase A2 inhibitory protein, and thus controls the biosynthesis of prostagladins and leukotrienes. The drug is marketed as a cream under the tradename Nerisone.

Alfatradiol (17a-estradiol, Ell-Cranell® alpha) is a stereoisomer of the female hormone 17b-estradiol. It inhibits the conversion of testosterone to the metabolite dihydrotestosterone (DHT) by suppressing 5a-reductase activity. In addition, by inhibiting 17b-dehydrogenase, it impedes the conversion process of androstenedione to testosterone, resulting in a reduction in the syntheses of testosterone and DHT. It also accelerates the conversion of testosterone to estradiol by stimulating aromatase, decreasing the level of testosterone and leading to a reduction in DHT. In addition, alfatradiol (17a-estradiol) has been reported to stimulate the generation of hair follicular matrix cells.
