7RKE, 7T2X - PubMed Abstract: 
Despite continued interest in the development of nonsteroidal estrogens and antiestrogens, there are only a few chemotypes of estrogen receptor ligands. Using targeted screening in a ligand sensing assay, we identified a phenolic thieno[2,3- d ]pyrimidine with affinity for estrogen receptor α. An efficient three-step synthesis of the heterocyclic core and structure-guided optimization of the substituents resulted in a series of potent nonsteroidal estrogens. The chemical tractability of the thieno[2,3- d ]pyrimidine chemotype will support the design of new estrogen receptor ligands as therapeutic hormones and antihormones.
