In Silico Evaluation of Tryptamine-Derived Schiff Bases as Modulators of the Serotonin 5-HT₂A Receptor
Abstract
Serotonin receptors, also known as 5-hydroxytryptamine (5-HT) receptors, are a diverse family of G protein-coupled and ligand-gated ion channel receptors that mediate the physiological effects of the neurotransmitter serotonin. These receptors are widely distributed throughout the central and peripheral nervous systems, where they regulate numerous processes including mood, cognition, thermoregulation, appetite, and gastrointestinal function. To date, seven distinct receptor families (5-HT₁ to 5-HT₇) comprising multiple subtypes have been identified, each exhibiting unique pharmacological profiles, signal transduction mechanisms, and tissue-specific expression. Due to their broad functional relevance, serotonin receptors are key therapeutic targets in the treatment of neuropsychiatric disorders such as depression, anxiety, schizophrenia, and migraine. Continued investigation into their structure-function relationships, signaling pathways, and ligand specificity holds significant promise for the development of more selective and effective pharmacological agents. The 5-HT₂A receptor is one of the most extensively studied subtypes of the serotonin receptor family due to its prominent role in both normal physiology and various neuropsychiatric conditions. The 5-HT₂A receptor is highly expressed in the cerebral cortex, especially in pyramidal neurons of the prefrontal cortex, where it plays a critical role in modulating perception, cognition, and mood. It has been implicated in…
