Saracatinib (AZD0530) is an oral, dual inhibitor of c-Src/Abl kinases initially developed by AstraZeneca for the treatment of cancer. The drug was tested for many neoplasms and reached phase III for ovarian cancer (in combination with paclitaxel), however without demonstrating any significant effect. Sarcatinib is also tested in patients with Alzheimer's Disease (Phase II). Its effect on Alzheimer's Disease patients is explained by inhibition of another kinase, Fyn, which is highly expressed in brain.

Synthélabo developed a saripidem (also known as SL 850274) as a potential anxiolytic agent that modulates the benzodiazepine-binding site on GABAA receptor via primary binding with ω1 subtype. Saripidem was studied in phase II clinical trials for the treatment of patients with anxiety disorders. However, information about the further development of the drug is not available.

Rifalazil (also known as KRM-1648) is a derivative of the antibiotic rifamycin. This orally administered ansamycin is under evaluation for treatment of various bacterial infections. Rifalazil kills bacterial cells by blocking off the β-subunit in RNA polymerase. This drug was originally developed as a therapeutic agent to replace rifampin in the treatment of tuberculosis. It also showed potential to treat indications caused by chlamydia trachomatis and chlamydia pneumoniae. Furthermore, it has been suggested as a potential drug in the treatment of gastric ulcer disease (which is caused by Helicobacter pylori) and antibiotic-associated colitis. Phase II studies evaluated the efficacy and safety of this drug in patients with chlamydia trachomatis and chlamydia seropositive patients. A phase 3 study was initiated including chlamydia seropositive patients. However, the development of rifalazil was terminated in 2013 due to severe side effects.

Elomotecan (BN 80927), a homocamptothecin derivative, inhibits both topoisomerase I and topoisomerase II mediated DNA relaxation. It potently inhibits proliferation of human tumor cells in vitro and in vivo. Elomotecan was being developed for the treatment of solid tumors.

Etaminile is an antitussive agent.

Mibolerone is a synthetic anabolic steroid. It binds both androgen and progesterone receptors and exerts both androgenic and progestagenic actions. Mibolerone (CHEQUE® Drops) was used in veterinary for estrous (heat) prevention in adult female dogs not intended primarily for breeding purposes. No prescription preparation, human or veterinary, is currently known to contain mibolerone worldwide.

Clodoxopone (LR 19731) is a hypoglycemic agent, developed in the 1980s by Italian company Lusofarmaco. In animal models, the drug lowered the plasma cholesterol and triglyceride levels in several experimental conditions after single or repeated treatments. Results of the clinical trials of the drug are not reported.

Farglitazar is a non-thiazolidinedione insulin sensitizer and agonist of peroxisome proliferator-activated receptor-gamma. GlaxoSmithKline was developing farglitazar for the treatment of liver fibrosis and Type 2 diabetes mellitus.

Evernimicin (SCH 27899) is an oligosaccharide antibiotic. It nteracts with the large ribosomal subunit (50S) and inhibits bacterial protein synthesis. Evernimicin exerts activity against a wide spectrum of gram-positive bacteria and activity against some gram-negative bacteria. Evernimicin was being studied for the treatment of susceptible bacterial infections however its development has been discontinued.

Cinoxolone is a derivative of glycyrrhetinic acid. Is is claimed to possess antiulcer properties.
