CRYSTAL STRUCTURE OF ESTROGEN RECEPTOR BETA COMPLEXED WITH ERB-041

Overview

We present the structure-based optimization of a series of estrogen, receptor-beta (ERbeta) selective ligands. X-ray cocrystal structures of, these ligands complexed to both ERalpha and ERbeta are described. We also, discuss how molecular modeling was used to take advantage of subtle, differences between the two binding cavities in order to optimize, selectivity for ERbeta over ERalpha. Quantum chemical calculations are, utilized to gain insight into the mechanism of selectivity enhancement., Despite only two relatively conservative residue substitutions in the, ligand binding pocket, the most selective compounds have greater than, 100-fold selectivity for ERbeta relative to ERalpha when measured using a, competitive radioligand binding assay.
