title: Inhibition of rat liver hydroxysteroid sulfotransferase activity by alkylamines.
abstract: Triethylamine, which was used as an elution solvent for column chromatography to purify chemically synthesized 3'-phosphoadenosine 5'-phosphosulfate (PAPS), was a potent inhibitor of rat liver sulfotransferase (ST) activities toward androsterone and dehydroepiandrosterone, but not ST activities toward cortisol and 2-naphthol. Examination of fourteen primary, secondary and tertiary amines revealed that a secondary amine, di-n-butylamine, and three tertiary amines, triethylamine, tri-n-propylamine and tri-n-butylamine, specifically inhibited ST activities toward androgen.
