Binding Assay: In an ERR alpha binding assay, GST-bound ERR alpha LBD was used, and all experiments other than that was the same as the ERR gamma binding assay.In an ERR beta binding assay, GST-bound ERR alpha LBD was used so that a final concentration was 10 nM and a fluorescein-conjugated coactivator PGC1a was 250 nM, and all experiments other than that was the same as the ERR gamma binding assay.In an ER alpha binding assay, a GST-bound ER alpha ligand-binding domain (LBD) was added to a 384 well plate to which the arylethene derivative of the present invention was added to a final concentration of 7.3 nM. Then, a fluorescein-conjugated coactivator PGC1a and a Tb-a-GST antibody were added to 250 nM and 5 nM, respectively, and beta-estradiol as an agonist was added to a final concentration of 4 nM. All subsequent experiments was the same as the ERR gamma binding assay.
