Extensive rigid analogue design maps the binding conformation of potent N-benzylphenethylamine 5-HT2A serotonin receptor agonist ligands.

ACS Chemical Neuroscience January 16, 2013 Jose I Juncosa, Martin Hansen, Lisa A Bonner et al.

Based on the structure of the superpotent 5-HT(2A) agonist 2-(4-bromo-2,5-dimethoxyphenyl)-N-[(2-methoxyphenyl)methyl]ethanamine, which consists of a ring-substituted phenethylamine skeleton modified with an N-benzyl group, we designed and synthesized a small library of constrained analogues to identify the optimal arrangement of the pharmacophoric elements of the ligand. Structures consisted...

Chronic treatment with LY341495 decreases 5-HT2A receptor binding and hallucinogenic effects of LSD in mice

Neuroscience Letters January 16, 2013 José L. Moreno, Terrell Holloway, Vinayak Rayannavar et al. 44 citations

Hallucinogenic drugs, such as lysergic acid diethylamide (LSD), mescaline and psilocybin, alter perception and cognitive processes. All hallucinogenic drugs have in common a high affinity for the serotonin 5-HT(2A) receptor. Metabotropic glutamate 2/3 (mGlu2/3) receptor ligands show efficacy in modulating the cellular and behavioral responses induced by hallucinogenic drugs. Here, we explored...

Prenatal Stress Induces Schizophrenia-Like Alterations of Serotonin 2A and Metabotropic Glutamate 2 Receptors in the Adult Offspring: Role of Maternal Immune System

Journal of Neuroscience January 16, 2013 Terrell Holloway, José L. Moreno, Adrienne Umali et al. 122 citations

It has been suggested that severe adverse life events during pregnancy increase the risk of schizophrenia in the offspring. The serotonin 5-HT 2A and the metabotropic glutamate 2 (mGlu2) receptors both have been the target of considerable attention regarding schizophrenia and antipsychotic drug development. We tested the effects of maternal variable stress during pregnancy on expression and...

Cognitive impairments from developmental exposure to serotonergic drugs: citalopram and MDMA

The International Journal of Neuropsychopharmacology January 11, 2013 Tori L. Schaefer, Curtis E. Grace, A Braun et al. 24 citations

Abstract We previously showed that developmental 3,4-methylenedioxymethamphetamine (MDMA) treatment induces long-term spatial and egocentric learning and memory deficits and serotonin (5-HT) reductions. During brain development, 5-HT is a neurotrophic factor influencing neurogenesis, synaptogenesis, migration, and target field organization. MDMA (10 mg/kg × 4/d at 2 h intervals) given on...

Ecstasy use and serotonin syndrome: a neglected danger to adolescents and young adults prescribed selective serotonin reuptake inhibitors.

International journal of adolescent medicine and health 2013 Yuriy Dobry, Timothy Rice, Leo Sher

At present, there are scarce clinical and basic lab data concerning the risk of acute serotonin toxicity from selective serotonin reuptake inhibitors (SSRIs) and 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) co-administration. The health care community can strongly benefit from efforts to address the high risks associated with serotonin syndrome from this specific drug combination. The aim...

Hippocampal serotonin depletion unmasks differences in the hyperlocomotor effects of phencyclidine and MK-801: quantitative versus qualitative analyses

Frontiers in Pharmacology 2013 Wendy K. Adams, Adam L. Halberstadt, Maarten Van den Buuse 11 citations

Antagonism of N-methyl-D-aspartate (NMDA) receptors by phencyclidine (PCP) is thought to underlie its ability to induce a schizophrenia-like syndrome in humans, yet evidence indicates it has a broader pharmacological profile. Our previous lesion studies highlighted a role for serotonergic projections from the median, but not dorsal, raphe nucleus in mediating the hyperlocomotor effects of PCP,...

Pre-treatment of BALB/c mice with a centrally acting serotonin antagonist (cyproheptadine) reduces mortality from Boophone disticha poisoning.

Clinical Toxicology 2013 M Mutseura, D Tagwireyi, L L Gadaga 7 citations

Crude extracts of Boophone disticha are used in Southern African traditional medical practice for the management of various illnesses and conditions and have also been abused for their claimed euphoric and hallucinogenic effects. Unfortunately, ingestion of Boophone disticha has resulted in toxicity and death. The results of a recent acute toxicity study in a rat model insinuated that central...

Serotonergic Hyperactivity as a Potential Factor in Developmental, Acquired and Drug-Induced Synesthesia

Frontiers in Human Neuroscience 2013 Berit Brogaard 46 citations

Though synesthesia research has seen a huge growth in recent decades, and tremendous progress has been made in terms of understanding the mechanism and cause of synesthesia, we are still left mostly in the dark when it comes to the mechanistic commonalities (if any) among developmental, acquired and drug-induced synesthesia. We know that many forms of synesthesia involve aberrant structural or...

Clinical Pharmacology of 3,4-Methylenedioxymethamphetamine (MDMA, “Ecstasy”): The Influence of Gender and Genetics (CYP2D6, COMT, 5-HTT)

PLoS One October 24, 2012 Ricardo Pardo‐lozano, M. Farré, Samanta Yubero‐lahoz et al. 67 citations

The synthetic psychostimulant MDMA (±3,4-methylenedioxymethamphetamine, ecstasy) acts as an indirect serotonin, dopamine, and norepinephrine agonist and as a mechanism-based inhibitor of the cytochrome P-450 2D6 (CYP2D6). It has been suggested that women are more sensitive to MDMA effects than men but no clinical experimental studies have satisfactorily evaluated the factors contributing to...

Serotonin

Encyclopedia of Life Sciences October 15, 2012 Efrain C. Azmitia 2 citations

Abstract Serotonin was discovered in 1949 and has been detected in all living aerobic organisms and in every tissue of the human body. In animals, serotonin functions both as a neurotransmitter and a trophic factor. As a neurotransmitter, serotonin can modify a variety of biological and behavioural functions, including sex, aggression, appetite, locomotor activity, learning and memory, sleep...
