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

Pexiganan is a 22-amino-acid synthetic cationic peptide. It is an analog of magainin 2, which is a host defense peptide isolated from frog skin. The drug is thought to act by disturbing the permeability of the cell membrane or cell wall. Pexiganan exhibited in vitro broad-spectrum antibacterial activity when it was tested against 3,109 clinical isolates of gram-positive and gram-negative, anaerobic and aerobic bacteria. It is currently in phase 3 clinical trials as a topical antimicrobial agent for the treatment of mild infections associated with diabetic foot ulcers. In vitro data for pexiganan acetate suggest that the drug does have hemolytic activity at concentrations relevant for antibacterial activity. In association with tigecycline, pexiganan administration could overcome antibiotic resistance and increase the effectiveness of treatment against P. aeruginosa sepsis.

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.

Timobesone is a topical corticosteroid and thiol ester derivative with anti-inflammatory activity.

Cu-64 is a radioisotope of copper with T1/2 12.7 hours. It decays by emission of beta+ particles with energies 0.653 (17.8%) MeV, which makes it suitable for positron emission tomography. The most widely used Cu chelators are DOTA (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid) and TETA (1,4,8,11-tetraazacyclotetradecane-1,4,8,11-tetraacetic acid). Cu-64 acetate is used as a model compound to study metabolism and distribution of Cu-64.

Prazarelix is gonadorelin (GnRH) antagonist. It is primarily used in assisted reproduction to control ovulation. The drug works by blocking the action of GnRH upon the pituitary, thus rapidly suppressing the production and action of luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

Stenbolone is an anabolic–androgenic steroid of the dihydrotestosterone group patented by Schering AG but never marketed. Ester prodrug of stenbolone is used as an anabolic–androgenic steroid for depot intramuscular injection under the brand names Anatrofin and Stenobolone.

Sotrastaurin, an orally-active, first-in-class immunomodulator, is under development by Novartis for the treatment of uveal melanoma and diffuse-large B-cell lymphoma. Sotrastaurin is a low molecular mass synthetic compound that potently inhibits the PKC α, β and the θ isoforms resulting in selective NF-κB inactivation. Sotrastaurin is a potent and selective pan-PKC inhibitor, mostly for PKCθ with Ki of 0.22 nM in a cell-free assay. Inhibition of PKC beta in B-cells results in prevention of NF-kB-mediated signaling and down regulation of NF-kB target genes. This may eventually lead to an induction of G1 cell cycle arrest and tumor cell apoptosis in susceptible tumor cells. This agent may act synergistically with other chemotherapeutic agents. PKC, a family of serine/threonine protein kinases overexpressed in certain types of cancer cells, is involved in cell differentiation, mitogenesis, inflammation, and the activation and survival of lymphocytes. Sotrastaurin is currently in phase II trials by Novartis for the treatment of large B-cell lymphoma and uveal melanoma. Sotrastaurin was in Phase II of clinical development for the prevention of acute rejection after solid organ transplantation and psoriasis, but this reseach had being discontinued.

Pregnanediol is a chief steroid metabolite of progesterone that is biologically inactive and occurs as pregnanediol glucuronate in the urine. Pregnanediol has two hydroxyl groups, at 3-alpha and 20-alpha. A test can be done to measure the amount of pregnanediol in urine. The urine test offers an indirect way to measure progesterone levels in the body. It is a standard in the colorimetric determination of urinary pregnanediol in clinical laboratories.
