Cardiovascular toxicity of dihydroxytryptamines. 1976

C R Creveling, and J Lundstrom, and B Highman

A comparison of the acute toxicity and a histological examination of the toxic effects in mouse of 4,7-; 5,6-; 5,7- and 6,7-dihydroxytryptamines and related compounds are present. A time and dose dependent induction of subepicardial lesions by 5,6-dihydroxytryptamine is demonstrated. The development of ischemic necrosis of the vaculature of the tail following 6,7-dihydroxytryptamine is described. The toxic effects of these tryptamines are discussed with regard to the phenomena of specific neurodegeneration induced by 5,6- and 5,7-dihydroxytryptamines.

D012701 Serotonin A biochemical messenger and regulator, synthesized from the essential amino acid L-TRYPTOPHAN. In humans it is found primarily in the central nervous system, gastrointestinal tract, and blood platelets. Serotonin mediates several important physiological functions including neurotransmission, gastrointestinal motility, hemostasis, and cardiovascular integrity. Multiple receptor families (RECEPTORS, SEROTONIN) explain the broad physiological actions and distribution of this biochemical mediator. 5-HT,5-Hydroxytryptamine,3-(2-Aminoethyl)-1H-indol-5-ol,Enteramine,Hippophaine,Hydroxytryptamine,5 Hydroxytryptamine
D013997 Time Factors Elements of limited time intervals, contributing to particular results or situations. Time Series,Factor, Time,Time Factor
D015115 5,6-Dihydroxytryptamine Tryptamine substituted with two hydroxyl groups in positions 5 and 6. It is a neurotoxic serotonin analog that destroys serotonergic neurons preferentially and is used in neuropharmacologic research. 3-(2-Aminoethyl)indole-5,6-diol,5,6 Dihydroxytryptamine
