We disclose herein the discovery of estrogen receptor α (ERα) selective estrogen receptor modulators (SERMs) of the tetrahydroisoquinoline series that incorporate novel conformationally restricted side chains as replacement of the aminoethoxy residue typical of SERMs. Molecular modeling studies used in conjunction with the X-ray crystal structure of the ERα ligand binding domain (LBD) with raloxifene (7) suggested a diazadecaline ...
