Propanocaine is a benzyl alcohol derivative with local anesthetics activity

Traxoprodil (CP-101,606) is a potent, selective N-Methyl-D-aspartate (NMDA) receptor (NR2B subunit) antagonist under development by Pfizer for its potential as a neuroprotectant in head injury and neurodegenerative disease. It is in phase II trials in the US and in phase I in Japan for the potential treatment of head injury, such as, Depressive Disorder, Major and Parkinson's Disease. CP-101,606 does not protect against glutamate-induced neurotoxicity in cultured cerebellar neurons, up to a dose of 10 uM. These results are consistent with CP-101,606 being a potent NMDA antagonist, selective for the type of NMDA receptor associated with the hippocampus. Some further investigation revealed that CP-101,606 was associated with a dose-related dissociation and amnesia. These results support the hypothesis that glutamate antagonists may be useful antidyskinetic agents. However, future studies will have to determine if the benefits of dyskinesia suppression can be achieved without adverse cognitive effects.

Naftypramide is a nonsteroidal anti-inflammatory drug. It was used in the treatment of gynecological inflammatory diseases.

Aranotin, a metabolite of Arachniotus aureus, possesses the antiviral and antibiotic properties. It inhibits viral RNA synthesis against strains of rhino-, coxsackie, polio- and parainfluenza viruses.

Fenalcomine is a coronary vasodilator, cardiotonic and local anesthetic agent. It was studied in the treatment of angina pectoris.

Taziprinone was studied as an antitussive agent. Information about the current use of this compound is not available.

Gliflumide is a compound with a long-lasting hypoglycemic effect. This blood glucose lowering sulfonamide has shown a large decrease of blood glucose levels in healthy volunteers who where administered the drug orally or intravenously. A very similar reaction but delayed and prolonged response was observed for this drug compared to other insulin secretion-stimulating compounds (such as glibenclamide). High affinity of gliflumide to plasma proteins has been suggested to contribute to this delayed activity.

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.

Mesocarb (sydnocarb or 3-(beta-phenylisopropyl)-N-phenylcarbamoylsydnonimine) is a psychomotor stimulant N-alkylated amphetamine derivative. Mesocarb is a selective inhibitor of dopamine uptake, it potently blocks dopamine transporter. It is very likely that mesocarb is being used by drug addicts. Mesocarb is included in the World Anti-Doping Agency’s list of substances and methods that are prohibited in sports. It is used in Russia for the treatment of a variety of neuropsychiatric comorbidities.
