5-hydroxytryptamine receptor

N-Acetyl-5-hydroxytryptamine (O-Demethylmelatonin) , also known as Normelatonin, is the immediate precursor of melatonin. It is produced from serotonin by the enzyme aralkylamine N-acetyltransferase and is converted to melatonin by acetylserotonin O-methyltransferase. It can potently activate TrkB receptor.

Trimipramine maleate (Surmontil maleate) appears to inhibit serotonin transport and norepinephrine uptake by nerve terminals. This increases available norepinephrine or serotonin and prolongs its action. Trimipramine Maleate is the maleate salt form of trimipramine, a tricyclic secondary amine of the dibenzazepine class, with an antidepressant property.

Paliperidone (9-hydroxyrisperidone)(Invega) is used as an atypical antipsychotic. It applies to the acute and maintenance treatment of schizophrenia. Chemically, paliperidone is the primary active metabolite of the older atypical antipsychotic risperidone.

Nuciferine ((-)-Nuciferine) is an alkaloid found within the plants Nymphaea caerulea and Nelumbo nucifera. It has a profile of action associated with dopamine receptor blockade.

Rotundine (Gindarine) (L-tetrahydropalmatine, L-THP) is a selective dopamine D1 receptor antagonist with IC50 of 166 nM.

Serotonin hydrochloride (Serotonin HCl) is an endogenous 5-HT receptor agonist, a monoamine neurotransmitter in the CNS, and a catechol O-methyltransferase (COMT) inhibitor(Ki=44 μM).

(E)-3,4,5-Trimethoxycinnamic acid (O-Methylsinapic acid) is a natural compound derived from the roots and rhizomes of Notopterygium incisum.

Harmine (Telepathine) is an alkaloid isolated from seeds of Peganum harmala.

Puerarin (Kakonein), also known as Kakonein, is a member of the class of compounds known as isoflavonoid C-glycosides. It is a 5-HT2C receptor antagonist.

Xanthotoxol (Psoralen) is a biologically active linear furocoumarin, shows strong pharmacological activities as anti-inflammatory, antioxidant, 5-HT antagonistic, and neuroprotective effects.

Serotonin (5-hydroxytryptamine) is a natural product from animals

Cannabigerol is a high affinity α±2-adrenergic receptor agonist, moderate affinity 5-HT1A receptor antagonist, and low affinity CB1 receptor antagonist ; also binds to the CB2 receptor; it can relieve interocular pressure, which may be of benefit in the treatment of glaucoma.

Jatrorrhizine (neprotin) is a protoberberine alkaloid isolated from Enantia chlorantha (Annonaceae) and other species. It was found to have antimicrobial and antifungal activity. It binds and noncompetitively inhibits monoamine oxidase (IC50 4 micromolar for MAO-A and 62 for MAO-B).

Harmine hydrochloride (telepathine hydrochloride) is extracted from Peganum Harmala Genus.

1. Isocorynoxeine (7-Isocorynoxeine) shows the effects of lowering blood pressure, vasodilatation, and protection against ischemia-induced neuronal damage. 2. Isocorynoxeine exhibits a significant neuroprotective effect against glutamate-induced HT22 cell death at the maximum concentration.

2'-O-Methylisoliquiritigenin, a compound synthesized by enzymes specifically induced in NR.2'-O-Methylisoliquiritigenin, isolated from the Arachis species, up-regulates 5-HT, NE, DA and GABA pathways, but does not put a very significant effect on ne NE pathway.

Eucalyptol, a natural monoterpenoid and cyclic ether found in eucalyptus species, effectively controls excessive airway mucus secretion and asthma by inhibiting pro-inflammatory cytokines. It serves as an efficacious treatment for non-purulent sinusitis, reducing inflammation and pain when applied topically, and demonstrating leukemic cell-killing capabilities in vitro.

Geissoschizine methyl ether, a major indole alkaloid found in Uncaria hook, is a key active component of Yokukansan with psychotropic effects. It is a potent serotonin A receptor agonist and a candidate for ameliorating aggressiveness and sociality by Yokukansan.

Gentisein (NSC-329491), a primary metabolite of Mangiferin, exhibits significant inhibition of serotonin uptake, demonstrating potency with an IC50 value of 4.7 µM[1][2].

Buspirone (Buspirone free base) is an azaspiro compound which has a role as an anxiolytic drug, a sedative, a serotonergic agonist and an EC 3.4.21.26 (prolyl oligopeptidase) inhibitor.

Jatrorrhizine chloride (Neprotine chloride) is a potent and orally active uptake-2 transporter inhibitor. It exhibits a critical neuroprotective role in H2O2-induced apoptosis via inhibition of the MAPK pathway in HT22 hippocampal neurons.

Myristicin (Myristicine) is a natural product found in spices and umbelliferous plants. Myristicin has anti-cholinergic, Antibacterial, and hepatoprotective effects, it also has anti-inflammatory properties related with its inhibition of NO, cytokines,chemokines, and growth factors in dsRNA-stimulated macrophages via the calcium pathway. Myristicin can induce Apoptosis as characterised by alterations in the mitochondrial membrane potential, cytochrome c release, Caspase-3 activation, PARP-cleavage and DNA fragmentation.
