Tryptophan and 5-hydroxytryptophan for depression.
BACKGROUND 5 Hydroxytryptophan (5-HTP) and tryptophan are so-called natural alternatives to traditional antidepressants, used to treat unipolar depression and dysthymia. OBJECTIVES To determine whether 5-HTP and tryptophan are more effective than placebo, and whether they are safe to use to treat depressive disorders in adults. SEARCH STRATEGY Trials were searched in computerized general (M...
متن کاملPrecancerous Loss of 5-Hydroxytryptophan Decarboxylase Activity
The purpose of this experimental work was to determine whether the precancerous loss of rat liver 5-hydroxytryptophan (5-HT) decarboxylase was associated with sequential atrophic alterations preceding hepatocarcinogenesis. To test whether such an association existed, three experimental conditions were employed in which hepato carcinogenesis was either markedly delayed or prevented. Under all th...
متن کاملInvestigation of multiphoton-induced fluorescence from solutions of 5-hydroxytryptophan.
It is reported (J. B. S. Shear, C. Xu and W. W. Webb, Photochem. Photobiol. 1997, 65, 931) that multiphoton near infrared excitation of 5-hydroxytryptophan results in a transient product with green fluorescence. Visible fluorescence from multiphoton excitation enables detection of 5-hydroxytryptophan with extremely high sensitivity and also has potential applications in imaging of biological sy...
متن کاملTissue immunoassay for 19F-tagged 5-hydroxytryptophan.
A new tool for magnetic resonance, L-6-heptafluorobutyryl-5-hydroxytryptophan, was synthesized and investigated using an antibody to perfluoroalkyl moieties developed previously. To be useful as an imaging agent, the compound must cross the blood brain barrier and then be concentrated in vesicles in serotonergic neurons in order to accumulate in sufficient quantity for in vivo detection to be p...
متن کامل5-Hydroxytryptophan: a clinically-effective serotonin precursor.
5-Hydroxytryptophan (5-HTP) is the intermediate metabolite of the essential amino acid L-tryptophan (LT) in the biosynthesis of serotonin. Intestinal absorption of 5-HTP does not require the presence of a transport molecule, and is not affected by the presence of other amino acids; therefore it may be taken with meals without reducing its effectiveness. Unlike LT, 5-HTP cannot be shunted into n...
