Title: Unique [3H]tryptamine binding sites in rat brain: distribution and pharmacology. Author: Wood PL, Pilapil C, LaFaille F, Nair NP, Glennon RA. Journal: Arch Int Pharmacodyn Ther; 1984 Apr; 268(2):194-201. PubMed ID: 6732364. Abstract: [3H]Tryptamine binding in rat brain is widely distributed with highest densities in the cortex, striatum and hippocampus. This binding is stereospecific and is potently displaced by tryptamine analogues and beta-carbolines. Phenethylamines also possess a weaker activity in displacing [3H]tryptamine. The strict structural requirements for binding to this site substantiate its unique character and suggest that it may represent a tryptamine receptor in the CNS.[Abstract] [Full Text] [Related] [New Search]
