  1. Listed are the physicochemical properties of the ligands with highest binding affinity for each of the eleven candidate target proteins
  2. nHA Number of hydrogen bond acceptors, nHD Number of hydrogen bond donors, nRot Number of rotatable bonds, nRing Number of rings, MaxRing Number of atoms in the biggest ring, nHet Number of heteroatoms, fChar Formal charge, nRig Number of rigid bonds, TPSA Topological polar surface area, logS Log of the aqueous solubility, logP Log of the octanol/water partition coefficient, logD LogP at physiological pH of 7.4, RO5 Rule of five
  3. The rule of five scores and integrates values for molecular weight, nHA, nHD, and logP for a synopsis of orally active drug-likeness. Asterisks mark ligands that do not fulfill the RO5 but have been applied orally in clinical studies. Molecular weight and RO5 were retrieved from ChEMBL, the other properties were predicted by ADMETlab
