Sulverapride is a methylsulfamoylbenzamide derivative patented by Societe d'Etudes Scientifiques et Industrielles de l'Ile-de-France for the treatment of lower urinary tract disorders

Manifaxine (GW 320659) is a highly selective neuronal norepinephrine and dopamine re-uptake inhibitor. It has been in phase II clinical trials by GlaxoSmithKline for the treatment of attention deficit hyperactivity disorder and obesity. Manifaxine development has been discontinued.

Tefludazine (Lu 18-012) is a mixed D2 and 5-HT2 receptor antagonist that was developed as a potential antipsychotic compound. It was shown that tefludazine induced a dose-dependent decrease in both nigra pars compacta (SNC) and ventral tegmental area (VTA) dopamine (DA) activity. The development of the drug was discontinued in Phase I due to toxicological findings in dogs.

Clothixamide is a dopamine antagonist. The compound was invented by Pfizer in the 1960s and is claimed to be useful for the chemotherapy of mental diseases and especially for the control of excited states. Also, clothixamide is claimed to have potent antiemetic properties.

Bromerguride is an ergot derivative with dopamine antagonistic activity. Bromerguride has been claimed to bind to 5-HT1A receptors and to have 5-HT agonist properties. The neuropharmacological effects caused by the drug in animals were characterized by a central depressant neuroleptic-like symptomatology; the neuroleptic activity of the Bromerguride being at least in the same order of magnitude as haloperidol.

Cyclophenazine is an antagonist of dopamine receptors, discovered by Eli Lilly. The drug is claimed to possess tranquilizing, anti-emetic action, and is able to potentiate the action of anticholinergic compounds in inhibiting the gastric secretion.

Sumanirole is a novel dopamine agonist with high affinity and efficacy at D2 dopamine receptors and has a substantial degree of selectivity for the D2 receptor over other dopamine receptor subtypes. It had been in clinical trials for the treatment of Parkinson’s disease and restless leg syndrome but these studies were terminated for the efficacy reason.

Savoxepine (also known as cipazoxapine), a tetracyclic compound, possesses a potent neuroleptic-like effects. This compound acts via dopamine D(2)-receptor blockade. Savoxepine was studied in phase II clinical trials in Europe for the treatment of patients with psychotic disorders; however, these studied were discontinued.

Trepipam is a benzazepine derivative. It is a D1-dopamine antagonist. Trepipam significantly reduced aggression in behaviorally disturbed adolescents and in acute schizophrenics without producing concomitant sedation. Trepipam specifically reduces aggressive and hyperactive behaviors in a wide range of laboratory tests in various species, without producing signs of overt CNS depression or neurological impairment. The drug is effective in reducing many forms of aggression including brain stimulated emotional behavior. Trepipam actually had little effect on gross behavior in mice or rats and only produced ataxia at lethal doses.
