The mechanistic basis for this “rotatable bond filter” is not clear, since its count does not relate to the in vivo clearance rate in rats.

WebAutoDock is not able to manage directly the flexibility associated to bonds comprised in cyclic molecules. The genetic algorithm is indeed not able to modify rotatable bonds in a concerted fashion, then the rotation of an intra-cyclic bond would lead to a distorted structure. For this reason, cyclic portions of the ligands are considered as rigid.
