INN:pridopidine [INN]
Source URL:

Class (Stereo):
CHEMICAL (ACHIRAL)



Pridopidine is an experimental drug candidate belonging to a class of agents known as dopidines, which act as dopaminergic stabilizers in the central nervous system. As a dopamine stabilizer, pridopidine is thought to reduce the effects of dopamine when there’s too much and increase its effects when there’s too little. Pridopidine, therefore, plays two opposing roles in the brain, which stabilize dopamine levels. In this way, pridopidine is thought to help the brain reestablish a normal balance of neurotransmitters, and thus regain control over motion. Pridopidine intended to treat Huntington’s disease movement symptoms. Pridopidine was well tolerated and had an adverse event profile similar to a placebo.

INN:carmoxirole [INN]

Class (Stereo):
CHEMICAL (ACHIRAL)



Carmoxirole is a dopamine D2 receptor agonist with limited central activity that modulates sympathetic activation and subsequently reduces pre-load and afterload in animals. It was shown, that carmoxirole induced beneficial effects on hemodynamic and neurohumoral parameters in heart failure. In addition, experimental evidence showed that carmoxirole lowered blood pressure in various models of hypertension mainly or exclusively through inhibition of noradrenaline release from sympathetic nerve endings. That effect of carmoxirole was mediated by presynaptic dopamine receptors with the characteristic that release inhibition was restricted to low rates of sympathetic nerve discharge.
Bicifadine (DOV-220075) is not a narcotic and is well-tolerated and, in preclinical studies, has been shown not to act at any opiate receptor, but inhibits monoamine neurotransmitter uptake by recombinant human transporters in vitro with a relative potency of norepinephrine:serotonin:dopamine of 1:2:17. Bicifadine was in Phase II clinical trial for pain caused by diabetic neuropathy, in addition, was in phase III clinical trial to treat Chronic Low Back Pain, but that studies were discontinued

INN:seproxetine [INN]

Class (Stereo):
CHEMICAL (ABSOLUTE)


Conditions:

Seproxetine, also known as (S)-norfluoxetine, is a selective serotonin reuptake inhibitor (SSRI). It is the most important active metabolite of the widely used antidepressant fluoxetine, but little is known about its pharmacological actions. Seproxetine was being investigated by Eli Lilly and Company as an antidepressant; however, a cardiac side effect was noted and development was discontinued.

INN:adrogolide
Source URL:

Class (Stereo):
CHEMICAL (ABSOLUTE)



Adrogolide is a chemically stable prodrug of the dopamine D1 receptor agonist A-86929. Adrogolide is rapidly converted in plasma to A-86929. A-86929 has high affinity and functional selectivity for the dopamine D1 receptor. Adrogolide has been in phase II clinical trials for the treatment of Parkinson's disease and cocaine abuse. However, this research has been discontinued. The adverse events associated with its use of adrogolide were of mild-to-moderate severity and included injection site reaction, asthenia, headache, nausea, vomiting, postural hypotension, vasodilitation, and dizziness.

INN:sonepiprazole
Source URL:

Class (Stereo):
CHEMICAL (ABSOLUTE)


Conditions:

Sonepiprazole exhibits highly specific binding to the D4 dopamine receptor with more than 100-fold selectivity for the D4 receptor over other receptors, including dopamine, serotonin, and adrenergic receptors. It is a neutral antagonist at the D4 dopamine receptor and is devoid of dopamine agonist activity. Sonepiprazole selectively induces c-fos expression in the prefrontal cortex and blocks behavioral, biochemical, and genomic effects of repeated amphetamine administration in rats. Sonepiprazole was investigated as an antipsychotic for the treatment of schizophrenia in a placebo-controlled clinical trial, but in contrast to its comparator olanzapine no benefits were found and it was not researched further for this indication.
Aplindore (DAB-452) is a small molecule that displays potent dopamine D2 receptor partial agonist activity in in vitro and in vivo assays and is predicted to have antipsychotic efficacy without motor side effects. Aplindore had been in phase II clinical trials for the treatment of Parkinson's disease and restless legs syndrome. Aplindore was generally well tolerated and there were no withdrawals due to adverse events and no serious adverse events.

Class (Stereo):
CHEMICAL (ABSOLUTE)


Conditions:

LY404039 [(-)-(1R,4S,5S,6S)-4-amino-2-sulfonylbicyclo[3.1.0]-hexane-4,6-dicarboxylic acid] is an agonist of orthosteric metabotropic glutamate receptor (mGluR)2/3. In addition, it acts as an agonist at dopamine D2 receptors. LY404039 demonstrated broad antipsychotic and anxiolytic efficacy across multiple animal models. LY-2140023 is a methionine amide prodrug of LY-404039 being developed by Eli Lilly & Co for the potential oral treatment of schizophrenia.

Class (Stereo):
CHEMICAL (ABSOLUTE)



Tesofensine (also known as NS-2330) is a novel triple monoamine reuptake inhibitor with intrinsic inhibitory activity on norepinephrine (NE), serotonin (5-HT), and dopamine (DA) transporter function. It was development by NeuroSearch as a potential therapy for Alzheimer's disease (AD) and Parkinson's diseases, but these efforts have been discontinued. In phase II clinical trials with tesofensine in obese individuals, dose-related reductions in body weight, body fat and waist circumference, as well as improvements in other obesity-related endocrine factors were observed and the FDA recently endorsed the phase III trial program for this agent.
