Currently used antipsychotics are characterized by multireceptor mode of action. While antagonism of dopamine D2 receptors is responsible for the alleviation of "positive" symptoms of schizophrenia and the effects at other, particularly serotonergic receptors are necessary for their additional therapeutic effects, there is no consensus regarding an "ideal" target engagement. Here, a detailed SAR analysis in a series of 45 novel azinesulfonamides of cyclic amine derivatives, involving the aryl-piperazine/piperidine pharmacophore, central alicyclic amine and azinesulfonamide groups has led to the selection of (S)-4-((2-(2-(4-(benzo[b]thiophen-4-yl)piperazin-1-yl)ethyl)pyrrolidin-1-yl)sulfonyl)isoquinoline (62)...

The dopamine transporter (DAT) is abundantly expressed in the striatum where it removes extracellular dopamine into the cytosol of presynaptic nerve terminals. It is the target of drugs of abuse and antidepressants. There is a loss of the DAT in Parkinson's disease affecting release of levodopa implicated in levodopa-induced dyskinesias. This study investigated the effect of cholesterol on DAT, serotonin transporter (SERT) and vesicular monoamine transporter 2 (VMAT2) in monkey and rat brains in vitro. DAT protein levels measured by Western blot remained unchanged with in vitro methyl-β-cyclodextrin (MCD) incubations to remove membrane cholesterol or with incubations to increase membrane cholesterol content...

Serotonin (5-hydroxytryptamine; 5-HT) is essential to intrauterine development, but its source is debated. We used immunocytochemistry to gauge 5-HT; its biosynthetic enzyme (tryptophan hydroxylase 1, TPH1); an importer (serotonin transporter, 5-HTT/SERT/SLC6A); other transporters (P-glycoprotein 1 [P-gp/ABCB1], OCT3/SLC22A3 and gap junction connexin-43); and the 5-HT degradative enzyme (monoamine oxidase A, MAOA) in sections of placentas. In humans, 5-HT was faintly stained only in first trimester trophoblasts, while TPH1 was not seen at any stage...

BACKGROUND: Reduced expression of the serotonin transporter (SERT) promotes anxiety and cocaine intake in both humans and rats. We tested the hypothesis that median raphe nucleus (MRN) and dorsal raphe nucleus (DRN) serotonergic projections differentially mediate these phenotypes. METHODS: We used virally mediated RNA interference to locally downregulate SERT expression and compared the results with those of constitutive SERT knockout. Rats were allowed either short access (ShA) (1 hour) or long access (LgA) (6 hours) to cocaine self-administration to model moderate versus compulsive-like cocaine taking...

The serotonin transporter (SERT) is important for reuptake of the neurotransmitter serotonin from the synaptic cleft and is also the target of most antidepressants. It has previously been shown that cholesterol in the membrane bilayer affects the conformation of the serotonin transporter. Although recent crystal structures have identified several potential cholesterol binding sites it is unclear whether any of these potential cholesterol sites are occupieed by cholesterol and functionally relevant. In the present study we focus on the conserved Cholesterol Site 1 (CHOL1) located in a hydrophobic groove between TM1a, TM5 and TM7...

Neurotransmitters pathways in fish and mammals are phylogenetically conserved. Therefore, the environmental presence of psychopharmaceuticals, such as fluoxetine (FLU), are likely to interact with fish serotonergic, dopaminergic and adrenergic systems, affecting their response and associated biological functions. Hence, the present work aimed at evaluating the effects of FLU in the transcription of genes involved in serotonin, dopamine and adrenergic transporters and receptors signalling in early stages of Danio rerio development...

The HeartWare HVAD is a small, third generation continuous flow pump that is intracorporeally placed for support of a failing ventricle in adult patients. This device is small in size when compared to other left ventricular assist devices and can therefore be used in smaller sized pediatric patients. We present our initial experience using the HVAD as a bridge to heart transplantation in the pediatric population. We performed a retrospective, single center, nonrandomized review of 17 pediatric patients who underwent HVAD implantation between June 2013 and March 2016...

Adrenal chromaffin cells (ACCs) are the neuroendocrine arm of the sympathetic nervous system and key mediators of the physiological stress response. Acetylcholine (ACh) released from preganglionic splanchnic nerves activates nicotinic acetylcholine receptors (nAChRs) on chromaffin cells causing membrane depolarization, opening voltage-gated Ca(2+) channels (VGCC), and exocytosis of catecholamines and neuropeptides. The serotonin transporter is expressed in ACCs and interacts with 5-HT1A receptors to control secretion...
