}The administration of DL-3-pyridylalanine (DL-3-PA, DL-α-amino-3-pyridinepropanoic acid) or L-3-PA significantly increased brain serotonin (5-HT) concentration without affecting the other tissue 5-HT concentrations in male Wistar rats. The increase in brain 5-HT upon the administration of DL or L-3-PA was maintained for a long time (at least 96h). DL and L-3-PA decreased tryptophan pyrrolase activity in the liver and increased free tryptophan concentration in the serum. These effects found in…

X-ray crystallographic analysis revealed that the peptide 1 adopts an extended conformation, which is similar to that of a Delta(Z)Phe analog, Boc-Leu-Delta(Z)-beta-(3-pyridyl)-alpha,beta-dehydroalanine (Delta( Z)3Pal) residue, which was synthesized via Erlenmeyer azlactone method.
