3-Iodothyronamine (T1AM) is a novel metabolite of thyroid hormone. In HEK-293 cells expressing an orphan G-protein coupled receptor, the trace amine receptor, T1AM, potently increased cAMP accumulation. In mice, T1AM 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 T1AM derivatives would be useful to study the biology and pharmacology of T1AM. Herein we describe efficient syntheses of [125I]-, [2H]-, and [ 3H]-T1AM.
