چکیده

The 5-HT7 receptor is the most recent addition to the 5-HT receptor family and has been linked to a variety of physiological and pathophysiological processes. Well established antidepressant pharmaceuticals have recently been found to activate the 5-HT7 receptor, supporting the role of the 5-HT7 receptor in the antidepressant mechanism. The synthesis of potent selective 5-HT7 receptor antagonists could afford a greater understanding of the 5-HT7 receptor function as well as lead to potential drug candidates. The synthesis of unfused biheteroaryl derivatives as 5-HT7 receptor ligands has been described within. These compounds have been tested for biological activity on the 5-HT6 and 5HT7 receptors. 4-(3’-Furyl)-2-(N-substituted-piperazino)pyrimidines were found to be potent 5HT7 receptor ligands. 4-(2’-Furyl)-2-(N-substituted-piperazino)pyrimidines have shown high selectivity for the 5-HT7 receptor over the 5-HT6 receptor.

Serotonin via 5-HT7 receptors activates p38 mitogen-activated protein kinase and protein kinase C epsilon resulting in interleukin-6 synthesis in human U373 MG astrocytoma cells.

Serotonin [5-hydroxytryptamine (5-HT)] is a widely distributed neurotransmitter which is involved in neuroimmunomodulatory processes. Previously, it has been demonstrated that 5-HT may induce interleukin (IL)-6 expression in primary rat hippocampal astrocytes. The present study was undertaken to investigate the molecular pathways underlying this induction of IL-6 synthesis. As a model system, w...

Stimulation of the parapyramidal region of the neonatal rat brain stem produces locomotor-like activity involving spinal 5-HT7 and 5-HT2A receptors.

Locomotion can be induced in rodents by direct application 5-hydroxytryptamine (5-HT) onto the spinal cord. Previous studies suggest important roles for 5-HT7 and 5-HT2A receptors in the locomotor effects of 5-HT. Here we show for the first time that activation of a discrete population of 5-HT neurons in the rodent brain stem produces locomotion and that the evoked locomotion requires 5-HT7 and...

Synthesis of a carbon-14 analogue of N-(aryl-methyl)-3-phenyl-acryl amidine-[carboxy-14C] and its derivatives as NR2B-selective NMDA receptor antagonist

Four amidine NR2B-selective NMDA receptor antagonists, N-( 2-methoxy benzyl) -3-phenyl-acrylamidine, N-[diduterio(2-methoxyphenyl) methyl]-3-phenyl-acrylamidine, N-benzyl-3-phenyl-acryl amidine and N-[diduterio(phenyl)methyl]-3-phenyl-acrylamidine, all fourlabeled with carbon-14 in the 1-position, have been synthesized as part of 5-step sequence fromBa14CO3.

Functional, molecular and pharmacological advances in 5-HT7 receptor research.

The 5-HT7 receptor was among a group of 5-HT receptors that were discovered using targeted cloning strategies 12 years ago. This receptor is a seven-transmembrane-domain G-protein-coupled receptor that is positively linked to adenylyl cyclase. The distributions of 5-HT7 receptor mRNA, immunolabeling and radioligand binding exhibit strong similarities, with the highest receptor densities present...

A 5-HT(7) receptor-mediated depolarization in the anterodorsal thalamus. I. Pharmacological characterization.

Little is currently known regarding the electrophysiological response elicited by 5-hydroxytryptamine-7 (5-HT(7)) receptor stimulation in the brain. Previous anatomical studies have shown that the anterior thalamus expresses a high density of 5-HT7 receptors. Therefore, we used whole-cell recording techniques in the in vitro brain slices to examine the effects of serotonin on neurons of the ant...
