Figure 3.
Proposed binding mode of MS-245 (4a) in the h5-HT6 receptor, looking through the extracellular side of the helical bundle. TM5, TM6 and TM7 are nearest to the viewer. The MS-245 ligand is rendered as a ball-and-stick model with the carbon backbone in green, and the side chains of residues whose heavy atoms fall within 4.0 Å of the ligand’s heavy atoms are rendered as capped sticks.
