We synthesized an analogue of the thyromimetic GC-1 bearing the same hydrop
hobic appendage as the estrogen receptor antagonist ICI-164,384. While havi
ng reduced affinity for the thyroid hormone receptors compared to GC-1, it
behaves in a manner consistent with a competitive antagonist in a transacti
vation assay. (C) 2001 Elsevier Science Ltd. All rights reserved.
