Thyroid Hormone Receptor Antagonist (1-850)

Thyroid hormone receptor antagonist (1-850) competitively blocks T3 binding to both TRalpha and TRbeta (IC50s = 1.5 µM), demonstrating ~1,000-fold lower affinity for TRalpha in intact cells compared with T3. This compound is specific, showing no effect on the activity of the related retinoic acid receptor alpha.Formal Name: 2-[1-(4-nitrophenyl)-4-piperidinylidene]-acetic acid-2-[[[3-(trifluoromethyl)phenyl]amino]carbonyl]hydrazide.
