Dacuronium is an aminosteroid, acting as a competitive antagonist of nicotinic acetylcholine receptors. In animals, dacuronium worked as a short-acting muscle relaxant with a rapid onset of action. In a clinical trial, dacuronium was markedly less potent than tubocurarine and did not show a rapid recovery from its action.

Roxibolone, an androstane derivative, possesses the anti-glucocorticoid activity and devoid of any affinity for the androgenic prostate and muscle receptors. This anabolic drug has never been marketed.

Cortisuzol is a glucocorticoid corticosteroid, discovered by the French company Roussel Uclaf, and claimed to have anti-inflammatory activity in a number of clinical case reports.

LAFLUNIMUS is an immunomodulator with anti-inflammatory activities. It inhibits prostaglandin endoperoxide H synthases 1 and 2 in vitro and in vivo. It also acts as an immunosuppressive agent being an inhibitor of mitochondrial dihydroorotate dehydrogenase and concomitant reducing agent of pyrimidine nucleotide pools.

Cicrotoic acid is a biochemical drug that acts on bile flow and liquid composition of human bile.

Nikkomycin Z is an antifungal drug that inhibits chitin synthase. It has been reported that it inhibits chitin synthases (Chs) 1 and 3, but not 2, of Saccharomyces cerevisiae. Later it was found that nikkomycin Z inhibited all three Chs isozymes of Candida albicans (CaChs). The IC(50) value for CaChs1 is 15 uM, for CaChs2 0.8 uM, and for CaChs3 13 uM. Nikkomycin Z is under development as an orphan product for treatment of coccidioidomycosis. Nikkomycin Z has been used in trials studying the treatment and basic science of Coccidioidomycosis. In February 2006, nikkomycin z was designated as an orphan drug for the treatment of Coccidioidomycosis.

Mazipredone is a glucocorticoid exerting anti-inflammatory, anti-allergic and anti-shock properties.

Nicocortonide is an anti-inflammatory corticosteroid for topical use.

Silydianin is a flavonolignan from Silymarin, which is the major constituent of milk thistle extract. Silydianin, an active constituent of Silybium marianum, have inhibitory properties against the P2Y12 receptor and block ADP-induced blood platelet activation. Silydianin has antiinflammatory activity, it regulates caspase-3 activation, affects cell membranes and acts as a free radical scavenger. Silydianin non-competitively inhibits the lipoxygenase from soybeans in vitro. It also inhibits the formation of prostaglandins in vitro.

Orestrate was developed as an estrogenic steroid that has never been marketed.
