Figure 5.
The binding sites of aniracetam and CX614 overlap. A, View parallel to the twofold axis showing that aniracetam (green) and CX614 (pink) overlap. In fact, rings 1 and 3 are nearly superimposable. B, View perpendicular to the twofold axis, showing that the modulators bind at the same “depth” in the dimer interface.
