Structure-guided synthesis of tamoxifen analogs with improved selectivity for the orphan ERRgamma.


PMID 16307879

Abstract

The design and synthesis of 4-hydroxytamoxifen (4-OHT) derivatives are described. The binding affinities of these compounds toward the orphan estrogen-related receptor gamma and the classical estrogen receptor alpha demonstrate that analogs bearing hydroxyalkyl groups display improved binding selectivity profiles compared with that of 4-OHT. An X-ray crystal structure of one of the designed compounds bound to ERRgamma LBD confirms the molecular basis of the selectivity.
