5-hiaa

5-Hydroxyindole-3-acetic acid (5-HIAA) is a breakdown product of serotonin that is excreted in the urine. Serotonin and 5HIAA are produced in excess amounts by carcinoid tumors, and levels of these substances may be measured in the urine to test for carcinoid tumors (NCI).

Niaprazine is a histamine H1-receptor antagonist exhibiting significant sedative properties.

p-Ethynylphenylalanine hydrochloride (4-Ethynyl-L-phenylalanine HCL) is a novel, potent, and specific inhibitor of TPH[1]. Its potential to selectively and reversibly inhibit serotonin biosynthesis may contribute to characterizing the role of serotonin in behavioral and physiological activities[1].

5-HYDROXYINDOLE-3-ACETIC ACID (Standard) is a reference standard for research and analysis in studies involving 5-HYDROXYINDOLE-3-ACETIC ACID. 5-Hydroxyindole-3-acetic acid (5-HIAA) is a breakdown product of serotonin that is excreted in the urine. Serotonin and 5HIAA are produced in excess amounts by carcinoid tumors, and levels of these substances may be measured in the urine to test for carcinoid tumors (NCI).
