Figures & data

Table 1. Active ERβ agonists used in the enriched dataset.

Figure 1. Results of the self-docking study. For each procedure the average RMSD (Å) is reported.

Figure 5. Virtual screening workflow. *The compounds that after the docking calculation showed the two H-bonds with H475 and the E305-R346 network system were taken into account. **The compounds that maintained the H-bonds with H475 and the E305-R346 network system for at least the 75% of MD simulation were considered.
