Abstract

[Carbonyl-(11)C]WAY-100635 is a potent and effective antagonist for the 5-HT(1A) receptor subtype. We aimed to assess the status of [carbonyl-(11)C]WAY-100635 and its main radio-metabolites, [carbonyl-(11)C]desmethyl-WAY-100635 and [carbonyl-(11)C]cyclohexanecarboxylic acid, on the basis of an improved radio-HPLC method. Common methods were characterized by preparative HPLC columns with long runtimes and/or high flow rates. Considering the short half-life of C-11, we developed a more rapid and solvent saving HPLC assay, allowing a fast, efficient and reliable quantification of these major metabolites.
