Pharmacophore models that showed a significant enrichment of highly
LXRβ-selective compounds. The models are named after the X-ray
crystal structure protein data bank22 code
from which they were originally derived. Blue spheres illustrate hydrophobic
features. Green arrows represent hydrogen bond acceptors. Brown spheres
represent aromatic interactions with indicated direction. The gray
spheres signify so-called exclusion volumes that represent the space
occupied by the protein. Model 1pc6 consists of two hydrophobic features,
one hydrogen bond acceptor, an aromatic interaction, and 31 exclusion
volumes. Model 1pqc consists of three hydrophobic features, one hydrogen
bond acceptor, and 458 exclusion volumes. Model 3fal consists of three
hydrophobic features, one hydrogen bond acceptor, and 514 exclusion
volumes.
