Telotristat etiprate (LX1606 Hippurate) is a novel, orally-delivered inhibitor of tryptophan hydroxylase that reduces serotonin production.
4-Ethynyl-L-phenylalanine is a selective, reversible, potent and competitive inhibitor of tryptophan hydroxylase (TPH). 4-Ethynyl-L-phenylalanine is a competitive inhibitor with regard to the substrate tryptophan, with a Ki of 32.6 μM. 4-Ethynyl-L-phenylalanine selectively and reversibly inhibits the biosynthesis of serotonin[1].
Fenclonine is a pharmaceutical intermediate.
4-Ethynyl-L-phenylalanine hydrochloride is a selective, reversible, potent and competitive inhibitor of tryptophan hydroxylase (TPH). 4-Ethynyl-L-phenylalanine hydrochloride is a competitive inhibitor with regard to the substrate tryptophan, with a Ki of 32.6 μM. 4-Ethynyl-L-phenylalanine hydrochloride selectively and reversibly inhibits the biosynthesis of serotonin[1].
4-Chloro-L-phenylalanine (L-PCPA) is a 5-HT biosynthesis inhibitor. 4-Chloro-L-phenylalanine is also a nonspecific antagonist of both isoforms of tryptophan hydroxylase (TPH1 and TPH2)[1].
Rodatristat ethyl (KAR5585) is an orally active tryptophan hydroxylase 1 (TPH1) inhibitor with nanomolar in vitro potency. Rodatristat ethyl reduces the level of 5-HT and significantly reduces pulmonary arterial hypertension (PAH)[1][2].
Rodatristat (KAR5417) is a potent tryptophan hydroxylase 1 (TPH1) inhibitor with an IC50 value of 33 nM, and shows robust reduction of intestinal serotonin (5-HT) levels in mice. Rodatristat also shows potent inhibition of TPH2 (IC50 of 7 nM)[1].
LP-533401 hydrochloride is a tryptophan hydroxylase 1 inhibitor that regulates serotonin production in the gut.
Telotristat ethyl (LX1606) is a novel, orally-delivered inhibitor of tryptophan hydroxylase that reduces serotonin production.
LX-1031 is a potent, orally available tryptophan 5-hydroxylase (TPH) inhibitor that reduces serotonin (5-HT) synthesis peripherally.
Telotristat (LP-778902) is a potent tryptophan hydroxylase inhibitor with an in vivo IC50 of 0.028 μM.
PCPA methyl ester hydrochloride (4-Chloro-DL-phenylalanine methyl ester hydrochloride), a reversible tryptophan hydroxylase inhibitor, is a serotonin (5-HT) synthesis inhibitor. PCPA methyl ester hydrochloride crosses the blood brain barrier and reduces 5-HT central availability[1][2].
LP-533401 is a Tryptophan hydroxylase 1 inhibitor that regulates serotonin production in the gut.
ACT-678689 (Compound Example 1.53.4) is a tryptophan hydroxylase (TPH) inhibitor with an IC50 of 8 nM[1].
6-Fluorotryptophan, a competitive inhibitor of tryptophan hydroxylase, produced a transient disruption of sleep in rats chronically implanted with EEG recording electrodes[1].
