tryptophan

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.

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-Acetyl-L-tryptophan (N-acetyltryptophan) is an inhibitor of neurokinin 1 receptor (NK1-receptor, NK1R).

5-Methoxy-DL-tryptophan is a molecule produced by endothelial cells to modulate inflammatory responses and protect against systemic inflammation.

N-Malonyl DL-tryptophan is a useful organic compound for research related to life sciences and the catalog number is T125055.

5-Bromo-DL-tryptophan is a natural product obtainable from Aspergillus fumigatus.

5-hydroxytryptophan (NSC-92523) is the immediate precursor in the biosynthesis of SEROTONIN from tryptophan. It is used as an antiepileptic and antidepressant.

N-Caffeoyltryptophan (trans-Caffeoyl-L-tryptophan), a potential Sirt inhibitor, is screened using coffee extract. N-Caffeoyltryptophan inhibited Sirt2 (IC50; 8.7 μM) better than Sirt1(IC50; 34μM).

L-5-Hydroxytryptophan (L-5-HTP), the immediate precursor in the biosynthesis of SEROTONIN from tryptophan, is used as an antiepileptic and antidepressant.

N-Malonyltryptophan is a useful organic compound for research related to life sciences. The catalog number is T125105 and the CAS number is 29399-11-9.

3-Acetylindole (3-Acetyl-1H-indole) can be used as a substituent and a probe to L-tryptophan for Sudlow site II.

H-Phe-Trp-OH (Phenylalanyland tryptophan) is a small molecular dipeptide compound involved in protein synthesis in the body.

H-D-Trp-OH (D-Tryptophan) is one of the 20 standard amino acids. The D-stereoisomer is occasionally found in naturally produced peptides (e.g. contryphan, the marine venom peptide).

Indole-3-carboxylic acid (3-Indoleformic acid) is a normal urinary indolic tryptophan metabolite .

Tetrahydropapaverine hydrochloride (Norlaudanosine HCl) , an analogue of salsolinol and tetrahydropapaveroline, has neurotoxicity on dopamine neurons.

Indole has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. It can be produced by bacteria as a degradation product of the amino acid tryptophan. It occurs naturally in human feces and has an intense fecal smell. At very low concentrations, however, it has a flowery smell, and is a constituent of many flower scents (such as orange blossoms) and perfumes.

Quinolinic acid (QUIN) is an endogenous N-methyl-D-aspartate (NMDA) receptor agonist synthesized from L-tryptophan via the kynurenine pathway.

Xanthurenic Acid (8-Hydroxykynurenic acid), a molecule arising from tryptophan metabolism by transamination of 3-hydroxykynurenine, activates mGlu2 3 Metabotropic glutamate receptors (mGlu2 and mGlu3).

Ac-DL-Trp-OH (N-Acetyl-DL-tryptophan) was study for its possible anti- inflammatory and antinociceptive activities from the extraction of a Turkish plant, Salsola grandis.

Glutaric acid is a simple five-carbon linear dicarboxylic acid. Glutaric acid is naturally produced in the body during the metabolism of some amino acids, including lysine and tryptophan

3-Indoleacrylic acid is a metabolite of tryptophan produced by Peptostreptococcus species. 3-Indoleacrylic acid has a beneficial effect on intestinal epithelial barrier function and mitigates inflammatory responses by immune cells.

Oxoadipic acid (2-Oxoadipic acid) is a key metabolite of the essential amino acids tryptophan and lysine.Important metabolite between the TCA cycle and lysine biosynthesis. Of interest for research on mitochondrial metabolite transporters.

L-(+)-Abrine (L-N-Methyltryptophan) is a toxic protein found in the jequirity seed.,can be used as a biomarker for abrin exposure.

Indolicidin is comprised of 13 amino acids, 5 of which are tryptophan residues, and the carboxylterminal arginine is carboxamidated. Indolicidin has the highest tryptophan content of any known protein.
