Title: Re-evaluation of the uptake of desoxyfructo-serotonin by human platelets, and of its effect on the uptake of serotonin.
Abstract:Employing C14-glucose and C14-serotonin (5HT) as precursors, we have synthesized desoxyfructo-5HT [1-desoxy-1-(5-hydroxytryptamine)-D-fructose] labelled either in the sugar or 5HT moieties, and examin...Employing C14-glucose and C14-serotonin (5HT) as precursors, we have synthesized desoxyfructo-5HT [1-desoxy-1-(5-hydroxytryptamine)-D-fructose] labelled either in the sugar or 5HT moieties, and examined the uptake of the labelled substrate by washed human platelets. Desoxyfructo-5HT appears to interact with the 5HT uptake site, effectively inhibiting the uptake of H3-5HT. However, our data indicate that contrary to published reports, the entry of desoxyfructo-5HT into platelet vesicles or cytoplasm is negligible.Read More
