Atigliflozin (also known as AVE2268), a substituted glycopyranoside, is a selective inhibitor of sodium-dependent glucose transporter 2. This drug reached phase II clinical trials as a new antidiabetic drug for the treatment of type 2 diabetes but further development was discontinued.

Hydromorphinol, an opioid, and is a derivative of morphine and possesses similar properties: sedation, analgesia, and respiratory depression. Hydromorphinol is under the control according to US Single Convention 1961.

Actinoquinol is sunscreen agent that absorbs Ultraviolet B light. Actinoquinol in combination with hyaluronic acid drops might be helpful for the human eye in the defense against photooxidative and other oxidative processes.

Tibeglisene (also known as BM 13907) is a pentynoic acid derivative patented by Boehringer Mannheim G.m.b.H. as insulin sensitizer with hypoglycemic activity. Tibeglisene is also able to reduce serum triglyceride and cholesterol concentrations. Tibeglisene exerts favor influences on glucose-transport activity.

Fonturacetam, also known as Phenylpiracetam, is marketed in Russia as Carphedon and Phenotropil. It is one of the first ever nootropic drugs and originally discovered in Russia. Fonturacetam acts on most neurotransmitter systems and has been used for its cognitive and physical enhancing properties, and also as an antidepressant.

Veliparib (ABT-888) is a potent inhibitor of PARP, has good oral bioavailability, can cross the blood-brain barrier, and potentiates temozolomide, platinums, cyclophosphamide, and radiation in syngeneic and xenograft tumor models. AbbVie is developing veliparib for the treatment of cancers. Clinical trials are underway worldwide, investigating veliparib primarily as part of a combination therapy in oncology indications such as brain, colorectal, melanoma, ovarian, prostate and pancreatic cancers.

Propazolamide is a sulfonamide derivative patented by American Cyanamid Co. useful in the treatment of glaucoma and epilepsy and as oral diuretics. Propazolamide acts as a carbonic anhydrase inhibitor.

Befiradol (also known as NLX-112) was initially developed by Pierre Fabre as a selective serotonin-1A receptor agonist for the treatment of cancer pain and neuropathic pain. However, these trials were discontinued. In 2013, the development and commercialization rights were licensed to Neurolixis. Neurolixis studied befiradol in Parkinson’s disease (PD) patients that exhibit dyskinesia. Dyskinesia is a side effect that appears after several years of action Levodopa, a drug that remains the gold standard treatment for PD. In 2019, FDA gave a positive response to Neurolixis’s befiradol to be tested in Phase 2 clinical in Parkinson's disease patients suffering from debilitating levodopa-induced dyskinesia.

Megalomicin is a Micromonospora-produced macrolide antibiotic complex. Megalomicin A component was studied most extensively. It inhibited the ATP-dependent acidification of lysosomes and intra-Golgi transport in vitro. Megalomicin induces a powerful inhibitory effect on HIV-1 replication at nontoxic concentrations by preventing the processing of HIV-1 gp160 envelope protein and the subsequent formation of infectious viral particles.
