Flumethasone 21-acetate is an anti-inflammatory corticosteroid. It has 300 times greater anti-inflammatory activity and 677 times greater capacity to promote liver glycogen deposition than hydrocortisone. It has anti-rheumatic potency 31 times higher than cortisol.

Cormethasone is a topical antiinflammatory corticosteroid discovered by Du Pont.

PYM50018 (also known as Myogane or SARSAGENIN) has demonstrated neuroprotective effects in several preclinical models. It was observed that PYM50018 protects against neuronal damage, increases neurite outgrowth, reverses oxidative damage and reversed neuronal apoptosis. PYM50018 is in phase I clinical study for the treatment of amyotrophic lateral sclerosis (ALS).

Betacetylmethadol is a synthetic narcotic analgesic under international control according to the UN Single Convention 1961.

Clogestone Acetate (AY-11440) is a steroidal progestin that was synthesized in 1964 and was investigated as a progestin-only contraceptive but was never marketed.

Trestolone is a synthetic androgen that inhibits the release of follicle-stimulating hormone and impairs spermatogenesis. Luteinizing hormone is also suppressed, which cuts production of testosterone. The azoospermia and oligospermia are reversible after discontinuation of trestolone. Trestolone has androgenic and anabolic properties and loss of secondary sex characteristics is not seen. Like testosterone, trestolone undergoes enzymatic aromatization to an estrogen. The use of trestolone instead of testosterone for androgen replacement therapy could have health-promoting effects by reducing the occurrence of prostate disease. Trestolone had been in phase II clinical trial for the andropause control. However, this development was discontinued.

Clostebol is a synthetic anabolic-androgenic steroid, a derivative of the natural hormone testosterone. Clostebol is a Schedule III controlled substance used medically in topical ophthalmologic and dermatologic treatments. Due to potential use as a performance-enhancing drug, clostebol is banned by the World Anti-Doping Agency.

Orbofiban was developed as an orally active glycoprotein IIb/IIIa antagonist. By 2001, this drug had progressed to phase III clinical trials. Unfortunately, was found that orbofiban induced thrombocytopenia and thrombosis. In addition, despite no significant excess risk of intracranial hemorrhage, orbofiban was not effective in preventing ischemic stroke or transient ischemic attack. Besides, the use of this drug had led to an increase in mortality. Based on all these results further development of this drug was discontinued.
