Chemical Structure
1,1′-Ethylidenebis[L-tryptophan]
- CAS No.: 132685-02-0

IUPAC Name: (3S,4R,5R)-1-(2-hydroxyethyl)-2-(hydroxymethyl)piperidine-3,4,5-triol hydrochloride
InChIKey: DETVQFQGSVEQBH-PMACEKPBSA-N
SMILES: CC(N1C2=CC=CC=C2C(C[C@H](N)C(O)=O)=C1)N3C4=CC=CC=C4C(C[C@H](N)C(O)=O)=C3
Biological Activity: 1,1′-Ethylidenebis[L-tryptophan] is an orally active amino acid analog. 1,1′-Ethylidenebis[L-tryptophan] promotes the release of adrenocorticotropic hormone and corticosterone in rat plasma, and transiently inhibits CRH mRNA in the paraventricular nucleus of the hypothalamus via glucocorticoid negative feedback. 1,1′-Ethylidenebis[L-tryptophan] induces multi-tissue inflammation and fibrosis in rodents and human cells, increases the number of degranulated mast cells, and activates the IL-5 pathway in lymphocytes. 1,1′-Ethylidenebis[L-tryptophan] is activated by tryptophanyl-tRNA synthetase and replaces L-tryptophan during translation; it also interferes with tryptophan metabolism in mice via the kynurenine pathway and dynamically alters their plasma quinolinic acid levels. 1,1′-Ethylidenebis[L-tryptophan] can be used for studies on metabolism-related mechanisms[1][2][3].
