oxitriptan
An aromatic amino acid with antidepressant activity. In vivo, oxitriptan is converted into 5-hydroxytryptamine (5-HT or serotonin) as well as other neurotransmitters. Oxitriptan may exert its antidepressant activity via conversion to serotonin or directly by binding to serotonin (5-HT) receptors within the central nervous system (CNS). Endogenous 5-hydroxytryptophan (5-HTP) is produced from the essential amino acid L-tryptophan. Exogenous therapeutic 5-HTP is isolated from the seeds of the African plant Griffonia simplicifolia. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
