serotonin

Serotonin (5-hydroxytryptamine) is a monoamine neurotransmitter in the CNS and an endogenous 5-HT receptor agonist. Serotonin regulates the nervous system, digestive system and cardiovascular system.

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.

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].

DL-Tryptophan ((±)-Tryptophan) containing dipeptides are interesting ingredients for functional foods as a natural prevention for hypertension with reduced side effects due to its selective inhibition of the C-domain. Low thalamic Tryptophan uptake appears to be a strong, independent predictor of long survival in patients with previous glioma treatment.

N-(p-Coumaroyl) Serotonin, a polyphenol isolated from the seeds of safflower, exhibits antioxidant, cardioprotective effects after ischemia, and antitumor activity. It may improve vascular distensibility and reduce cardiovascular risk. N-(p-Coumaroyl) Serotonin ameliorates atherosclerosis and distensibility of the aortic wall in vivo, and is commonly used in atherosclerosis research.

Bufoserotonin C, an indole alkaloid derived from the traditional Chinese medicine Chansu, exhibits antitumor activity and demonstrates an IC50 value of 34.3 μM in A549 cells [1] [2].

N-Feruloylserotonin ((E Z)-Moschamine) is a selective FAAH inhibitor that inhibits [H]-AEA uptake and cell proliferation at low concentrations.

L-Tryptophan (Tryptophane), an essential amino acid, is necessary for normal growth in infants and for nitrogen balance in adults. It is a precursor of SEROTONIN (hence its use as an antidepressant and sleep aid) and of INDOLE ALKALOIDS in plants. It can be a precursor to NIACIN, although inefficiently in mammals.

Mianserin hydrochloride (Org GB 94) is a tetracyclic compound with antidepressant properties that blocks alpha-adrenergic, histamine H1, and certain serotonin receptors; it may cause drowsiness and hematological issues.

Reserpine (Serpalan) is an alkaloid isolated from the root of Rauwolfia serpentina. As an inhibitor of vesicular monoamine transporter 2 (VMAT2), it suppresses the uptake of norepinephrine into storage vesicles, leading to depletion of catecholamines and serotonin in central and peripheral nerve terminals. It has antihypertensive and antipsychotic effects and can be used to induce gastric ulcer and depression models.

Pyridoxine hydrochloride (Vitamin B6) is the 4-methanol form of vitaminB6 which is converted to pyridoxal phosphate which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid.

4-aminobenzoic acid is an organic acid with UV-absorbing and antifibrotic properties. When exposed to light, 4-aminobenzoic acid absorbs UV light and releases excess energy through a photochemical reaction, which may cause DNA damage.4-aminobenzoic acid also increases oxygen uptake at the tissue level and may enhance monoamine oxidase (MAO) activity to promote serotonin degradation, which in excess may lead to fibrotic Changes.

Cinchonidine (L-Cinchonidine) is an alkaloid extracted from Cinchona officinalis. It is a pseudo-enantiomer and stereoisomer of cinchonine.

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.

L-5-Hydroxytryptophan (L-5-HTP) is a naturally occurring amino acid and dietary supplement that serves as a precursor to the neurotransmitter serotonin. It can be used as an antidepressant, appetite suppressant, and sleep aid, and acts as an antagonist to reserpine. L-5-HTP is widely used in research on myoclonus, fibromyalgia, migraine, and cerebellar ataxia, and is also commonly used to induce epilepsy models.

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.

5-Hydroxytryptophan (NSC-92523) is a metabolite of tryptophan and a direct precursor of serotonin. It is a substrate of aromatic amino acid decarboxylase and can be used to induce depression models.

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.

5-Hydroxyindole-3-acetic acid (5-HIAA) is a breakdown product of serotonin that is excreted in the urine. Serotonin and 5HIAA are produced in excess amounts by carcinoid tumors, and levels of these substances may be measured in the urine to test for carcinoid tumors (NCI).

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

Allura Red AC (CI 16035) is a very important food azo dye used in the food, pharmaceutical, paper, cosmetic and textile industries.Allura Red AC promotes susceptibility to experimental colitis via mouse intestinal serotonin.

Hymenidin HCl is a natural alkaloid isolated from Hymeniacidon sp. and acts as a serotonin (5-HT) receptor antagonist. Hymenidin HCl inhibits voltage-gated potassium channels (Kv), exhibits selective inhibition of CDK5, affects cellular signaling, and induces apoptosis in cancer cells.
