5-HT Receptor

Serotonin Receptor; 5-hydroxytryptamine Receptor

5-HT receptors (Serotonin receptors) are a group of G protein-coupled receptors (GPCRs) and ligand-gated ion channels (LGICs) found in the central and peripheral nervous systems. Type: 5-HT1, 5-HT2, 5-HT3, 5-HT4, 5-HT5, 5-HT6, 5-HT7. They mediate both excitatory and inhibitory neurotransmission. The serotonin receptors are activated by the neurotransmitter serotonin, which acts as their natural ligand. The serotonin receptors modulate the release of many neurotransmitters, as well as many hormones. The serotonin receptors influence various biological and neurological processes such as aggression, anxiety, appetite, cognition, learning, memory, mood, nausea, sleep, andthermoregulation. The serotonin receptors are the target of a variety of pharmaceutical drugs, including many antidepressants, antipsychotics, anorectics,antiemetics, gastroprokinetic agents, antimigraine agents, hallucinogens, and entactogens.

    Viloxazine
    99.15%
    Viloxazine is a non-brain-penetrant, selective norepinephrine transporter (NET) inhibitor (IC50= 0.26 μM) and 5-HT receptor modulator. Viloxazine antagonizes 5-HT2B receptors (Ki=4.2 μM) and agonizes 5-HT2C receptors (EC50= 32 μM), respectively, and enhances 5-HT neurotransmission by modulating 5-HT2B/C receptors. Viloxazine also competitively inhibits NET from increasing NE and DA levels in the synaptic cleft, and can be used in the study of attention deficit hyperactivity disorder (ADHD).
