Novel highly potent serotonin 5-HT7 receptor ligands: structural modifications to improve pharmacokinetic properties.
نویسندگان
چکیده
Here we report the synthesis, pharmacological and pharmacokinetic evaluation of a pilot set of compounds structurally related to the potent and selective 5-HT7 ligand LP-211. Among the studied compounds, N-pyridin-3-ylmethyl-3-[4-[2-(4-methoxyphenyl)phenyl]piperazin-1-yl]ethoxy]propanamide (4b) showed high affinity for 5-HT7 receptors (K(i)=23.8 nM), selectivity over 5-HT1A receptors (>50-fold), in vitro metabolic stability (82%) and weak interaction with P-glycoprotein (BA/AB=3.3). Compound 4b was injected ip in mice to preliminarily evaluate its distribution between blood and brain.

Design and Synthesis of Novel Serotonin Receptor Ligands
Novel and potent ligands to the serotonin7 (5-HT7) receptor have been synthesized. The synthesized compounds include a set of substituted pyrimidines which show high affinity to the 5-HT7 receptor, synthesized by previously described methods [1,2] in high yield. Comparing the affinities of substituted pyrimidines to previously calculated models [3,4] yielded new hypotheses about the nature of i...
متن کاملNovel agonists for serotonin 5-HT7 receptors reverse metabotropic glutamate receptor-mediated long-term depression in the hippocampus of wild-type and Fmr1 KO mice, a model of Fragile X Syndrome
Serotonin 5-HT7 receptors are expressed in the hippocampus and modulate the excitability of hippocampal neurons. We have previously shown that 5-HT7 receptors modulate glutamate-mediated hippocampal synaptic transmission and long-term synaptic plasticity. In particular, we have shown that activation of 5-HT7 receptors reversed metabotropic glutamate receptor-mediated long-term depression (mGluR...
متن کاملIn the search for selective ligands of 5-HT5, 5-HT6 and 5-HT7 serotonin receptors.
In recent years much attention has been focused on the functional importance of 5-HT5, 5-HT6 and 5-HT7 receptors in the pathogenesis of neuropsychiatric and other diseases. In this connection, intensive studies with ligands of these receptors are currently in progress. Recognition of the structural characteristics responsible for the binding of a ligand molecule to an appropriate receptor, and ...
متن کاملSynthesis of Selective 5-HT7 Receptor Antagonists
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 antagonis...
متن کامل7-3-Chlorophenypiperazinylalkyl derivatives of 8-alkoxy-purine-2,6-dione as a serotonin receptor ligands with potential antidepressant activity.
BACKGROUND The previous study showed that arylpiperazine can condition affinity to α-adrenoceptors, 5-HT1A/5-HT2A receptors and compounds with arylpiperazine had antidepressant-like effect. The aim of this study was to determine the antidepressant-like activity of new arylpiperazines containing novel 8-alkoxy-purine-2,6-dione fragments. METHODS New 3-chloroarylpiperazinylalkyl analogs of 8-al...
