Ocaperidone [R 79598] is an equipotent antagonist of central dopamine D2 and serotonin2 receptors being investigated as a potential antipsychotic agent. Ocaperidone is a benzisoxazol piperidine antipsychotic primarily binds and with high affinity to 5-HT2 (serotonin) receptors, alpha1 and alpha 2 adrenergic receptors, dopamine D2 receptors and histamine H1 receptors. Ocaperidone is an antagonist primarily at the 5HT and D2 receptors. A proposed mechanism of action is the central D2 receptor blockade which is common to all neuroleptics that are used to treat positive symptoms of schizophrenia.

Spirilene is an antipsychotic agent. In rabbit caudate nucleus (CN) spirilene exhibited Ki value of 3.5 uM at the 5-HT1R site, but produced less than 50% inhibition of [3H]5-HT binding to the 5-HT1D site even at concentrations as high as 100 uM.

ACP-104 or N-Desmethylclozapine (NDMC), or norclozapine is a major metabolite of clozapine, which was developed like a small molecule drug candidate by ACADIA for treatment schizophrenia. ACP-104 combines M1 muscarinic agonist, 5-HT2A inverse agonist, and D2 and D3 dopamine partial agonist in a single compound and, therefore, uniquely addresses what ACADIA believed are the three most promising target mechanisms for treating schizophrenia. Then drug was discontinued, because the study did not meet its primary endpoint of antipsychotic efficacy or any of the secondary endpoints. Neither dose of ACP-104 demonstrated improved efficacy as compared to placebo. The most common adverse events in the treatment arms relative to placebo were increased salivation, tachycardia, and dyspepsia, which were noted to be dose-related. There was no clinically significant decrease in neutrophil counts in the study drug arms.

Targets:
Dasotraline, also known as SEP-225,289, is a serotonin-norepinephrine-dopamine reuptake inhibitor (SNDRI). It has an extended half-life (47-77 hours) that supports the potential for plasma concentrations yielding a continuous therapeutic effect over the 24-hour dosing interval at steady state. Dasotraline has shown a lower potential for abuse than methylphenidate in clinical testing. Dasotraline was discovered by Sunovion Pharmaceuticals Inc. and is currently in development to evaluate its use in treating ADHD in adults and children, and BED in adults in the United States. It has not been approved by the U.S. Food and Drug Administration (FDA) for the treatment of ADHD, BED or any other disorder.

Fosopamine (also known as Sim 2055), is a prodrug of epinine was studied for the treatment of renal failure and of essential hypertension. However, phase II of clinical trials in Italy was discontinued in 1995. Information about the current development of this drug is not available.

Vanoxerine, also known as GBR-12909, is a piperazine derivative exhibiting potent selective inhibition of sodium-dependent dopamine reuptake transporters. Vanoxerine has been in clinical trials for Parkinsonism, depression and cocaine addiction but lacked efficacy. Vanoxerine has also been observed as a potent blocker of the following channels: cardiac hERG/IKr potassium channel, Calcium channel, voltage-dependent, L type, alpha 1C subunit (also known as Cav1.2) and voltage-gated sodium channel Nav 1.5. Vanoxerine was studied as a potential treatment for atrial fibrillation. However, phase III clinical trials for this condition were terminated because of cardiac safety concerns. Research also indicates that vanoxerine may have additional mechanisms of action including antagonist action at nicotinic acetylcholine receptors (nAChRs).

AstraZeneca R&D Charnwood (formerly Astra Charnwood, a subsidiary of AstraZeneca) was developing sibenadet (Viozan, AR-C68397AA) for the potential treatment of chronic obstructive pulmonary disease and asthma. Sibenadet is a dual D2 dopamine receptor, beta2-adrenoceptor agonist that combines bronchodilator activity with the sensory afferent modulating effects associated with D2-receptor agonism. Development of sibenadet has been discontinued due to disappointing efficacy findings.

Fallypride F-18 is a radiolabeled form of dual dopamine D2/D3 receptor antagonist. It is used as a PET tracer to characterize the distribution and binding potential of striatal and extrastriatal dopamine D2/D3 receptors in animals as well as in normal and diseased human brain.

Conditions:
Eptapirone is a potent, selective and efficacious 5-HT1A receptor agonist. In rats, it is readily bioavailable after oral administration. Likely, because of its high efficacy at 5-HT1A receptors, Eptapirone exerted powerful antidepressant- and anxiolytic-like activity in animal models. Eptapirone given in the evening suppresses REM (rapid eye movement) sleep more than buspirone and implies a greater central effect on serotonin receptors, which is consistent with the preclinical data that indicate it has greater efficacy than buspirone. It has little effect on other sleep stages. Eptapirone has been in phase I clinical trials for the treatment of anxiety and major depressive disorder. However, this research has been discontinued.

Mafoprazine is a phenylpiperazine derivative exerting postsynaptic dopamine D2 receptor blocking activity and alpha-adrenergic activity (alpha 1 receptor blocking activity and alpha 2 receptor stimulating activity). In animal models, mafoprazine demonstrated antipsychotic, aggression-inhibiting and cataleptogenic actions.
