LABELLED STEROIDS, PROCESS FOR THEIR PREPARATION AND INTERMEDIATES, THEIR USE IN THE LOCALIZATION OF THE GLUCOCORTICOID RECEPTORS AND IN THE DOSAGE OF THE NUMBER OF BINDING SITES

摘要

Novel radioactive steriods labelled with tritium of the formula I wherein 3H is tritium and R and R1 are individually selected from the group consisting of hydrogen, alkyl of 1 to 6 carbon atoms and acyl of an organic carboxylic acid of 1 to 10 carbon atoms useful for revealing receptors of glucocorticoids and in determining the number of fixation sites on glucocorticoids and novel intermediates.
