Molecular Tour

Selective estrogen receptor modulators, such as estradiol 17-derived metal complexes, have been synthesized as targeted probes for the diagnosis and treatment of breast cancer. Here, we report the detailed 3D structure of estrogen receptor alpha ligand-binding domain (ER-LBD) bound with a novel estradiol-derived metal complex, estradiol-pyridinium tetra acetate europium (III) at 2.6 resolution. This structure provides important information pertinent to the design of novel functional ER targeted probes for clinical applications.
