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.

    Lofepramine
    Inhibitor ≥99.0%
    Lofepramine (Lopramine) is a modified tricyclic and orally active antidepressant. Lofepramine inhibits the uptake of Noradrenaline (NA) (HY-13715) and 5-hydroxytryptamine (5-HT) with IC50s of 2.7 μM and 11 μM, respectively. Lofepramine exerts its antidepressant activity by promoting noradrenergic neurotransmission. Lofepramine also enhances serotonergic neurotransmission by inhibiting neuronal uptake of 5-HT and tryptophan pyrrolase. Lofepramine exhibits significant anxiolytic properties. .
