dl tryptophan

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.

5-Bromo-DL-tryptophan is a brominated, racemic derivative of tryptophan at the 5-position of the indole ring, which can be isolated from Aspergillus fumigatus. 5-Bromo-DL-tryptophan can serve as a precursor or intermediate in drug synthesis. 5-Bromo-DL-tryptophan is a competitive inhibitor of L-tryptophan.

6-Methyl-DL-tryptophan is a reagent used in biochemical reactions.

Fenclonine (CP-10188) is a selective and irreversible inhibitor of tryptophan hydroxylase, a rate-limiting enzyme in the biosynthesis of serotonin (5-HYDROXYTRYPTAMINE). Fenclonine(CP-10188) acts pharmacologically to deplete endogenous levels of serotonin.

pCPA methyl ester hydrochloride (4-Chloro-DL-phenylalanine methyl ester hydrochloride) is an inhibitor of tryptophan hydroxylase inhibitor and 5-HT synthesis. pCPA methyl ester hydrochloride is permeable across the blood-brain barrier and reduces 5-HT central availability.

3-Hydroxykynurenine (3-hydroxy-DL-Kynurenine) is an active metabolite of tryptophan and inhibits yeast and rat liver aldehyde dehydrogenase by 97 and 69%.

(Rac)-Indoximod (1-Methyl-DL-tryptophan) is a potent inhibitor of indoleamine 2,3-dioxygenase (IDO). Combined treatment with IFN-γ and (Rac)-Indoximod significantly suppresses the activity of α-SMA-expressing human cardiac myofibroblasts (hCMs) and promotes apoptosis by up-regulating the genes IRF-1, Fas, and FasL, effectively improving cardiac fibrosis[1].

DL-β-Hydroxybutyryl coenzyme A lithium, an intermediate in butyric acid fermentation and lysine and tryptophan metabolism, is synthesized from β-hydroxybutyric acid by short-chain-CoA synthase [1] [2].
