3-Iodothyronamine ( T(1)AM) is a novel metabolite of thyroid hormone. In HEK-293 cells expressing an orphan G-protein coupled receptor, the trace amine receptor, T(1)AM, potently increased cAMP accumulation. In mice, T(1)AM rapidly induced hypothermia and bradycardia within minutes of administration. These results suggest the existence of a new signaling pathway, the stimulation of which leads to rapid physiological and behavioral consequences. Isotope-labeled T(1)AM derivatives would be useful to study the biology and pharmacology of T(1)AM. Herein we describe efficient syntheses of [I-125]-, [H-2]-, and [H-3]- T(1)AM.
