Abstact

In this communication, we wish to describe the discovery of a novel series of 6-azauracil-based thyromimetics that possess up to 100-fold selectivities for binding and functional activation of the beta(1)-isoform of the thyroid receptor family. Structure-activity relationship studies on the 3,5- and 3'-positions provided compounds with enhanced TR beta affinity and selectivity. Key binding interactions between the 6-azauracil moiety and the receptor have been determined through of X-ray crystallographic analysis.
