DICHLORISONE is a synthetic corticosteroid used topically for its glucocorticoid activity in the treatment of various skin disorders.

Osaterone acetate (previously known as TZP-4238), a synthetic steroidal anti-androgen agent. Osaterone acetate is used in veterinary in Europe in the treatment of benign prostatic hyperplasia (BPH) in male dogs. Osaterone acetate inhibits the effects of an excess of male hormone (testosterone) through various mechanisms. It competitively prevents the binding of androgens to their prostatic receptors and blocks the transport of testosterone into the prostate. Osaterone acetate was also investigated in Japan in the treatment of prostate cancer and BPH and, in addition, was studied in postmenopausal osteoporosis in humans. However, these studies were discontinued.

Rapastinel (formerly known as GLYX-13) is an investigational intravenous formulation of a novel NMDA receptor partial agonist, which is being evaluated for adjunctive treatment of Major depressive disorder, and has shown a rapid onset of antidepressant efficacy 1 day after a single dose in a Phase 2 clinical trial of patients with Major depressive disorder who had an inadequate response to one or more antidepressants. No psychotomimetic or hallucinogenic side effects were observed with rapastinel. Few adverse events were reported by 5% or more of subjects and these were rated as mild or moderate. These included headache, somnolence, dizziness, dysgeusia, and fatigue. On January 29, 2016, Allergan (who acquired Naurex in July 2015) announced that rapastinel had received Breakthrough Therapy designation from the U.S. FDA for adjunctive treatment of major depressive disorder.

Nisterime is a dihydrotestosterone derivative. Nisterime acetate (ORF-9326) was shown to inhibit implantation in several species. It is also interrupts the postimplantation stage of gestation.

Quindecamine (also known as UCL-1407) is quinaldine derivative with antibiotic and fungicidal activity. Treatment of rats and mice with Quindecamine (250 mg/kg/ day) each day for 4 weeks followed by 500 mg/kg/day for 2 more weeks reduced spontaneous motility and body weight but produced no pathological abnormalities of the various organs studied. In vitro, the drug showed very good activity against Staphylococcus aureus, Streptococcus hemolyticus, Candida albicans, Trichophyton mentagrophytes, and T. vaginalis. The drug had very good activity in 180 human subjects with various bacterial and mycotic diseases of the skin and mucosa when applied as a 1% salve.
