Binds specifically to an estrogen response element and activates reporter genes controlled by estrogen response elements (By similarity). Publication Abstract from PubMed An inverse agonist of estrogen-related receptor-gamma (ERRgamma), an orphan nuclear receptor encoded by E srrg, enhances sodium iodide symporter-mediated radioiodine uptake in anaplastic thyroid cancer (ATC) cells, thereby facilitating responsiveness to radioiodine therapy in vitro. We synthesized potent, selective, and orally bioavailable ERRgamma-inverse agonists and evaluated their activity by analyzing in vitro pharmacology and absorption, distribution, metabolism, excretion, and toxicity profiles. X-ray crystallographic analysis of the ligand and ERRgamma complex showed that 35 completely binds to the target protein (PDB 6A6K ). Our results showed improved radioiodine avidity in ATC cells through compound 35-mediated upregulation of iodide-handling genes, leading to enhanced responsiveness to radioiodine therapy in vitro. Importantly, in vivo (124)I-positron emission tomography/computed tomography imaging revealed that 35 increases radioiodine avidity in CAL62 tumors. Collectively, these results demonstrated that 35 can be developed as a promising treatment for ERRgamma-related cancer in the future.
