Background:

Target: thyroid hormone receptor

IC50: 1.5 μM

Thyroid hormone receptor antagonist (1-850) was screened from a library of more than 250000 compounds as the antagonist of thyroid hormone receptor with the highest affinity. Thyroid Hormone Receptor Antagonist, 1-850 is a cell-permeable hydrazinyl-carboxamide compound which functions as a selective and high-affinity thyroid receptor antagonist with the IC50 value of 1.5 μM in Hela cells [1].

The thyroid hormone receptor (TR) is a type of nuclear receptor that is activated by binding thyroid hormone, which plays a critical role in the regulation of metabolism and heart rate and the development of organisms. Thyroid hormone receptor antagonist (1-850) could competitively block T3 (L-triiodothyronine) binding to both TRα and TRβ, and suppress T3 mediated interaction of TRα with nuclear receptor coactivator (NRC) as well as prevent the stimulation of gene expression [1].
