  1. Lipinski allows for one violation. Lipinski* is a stricter version that allows for no violations. Ghose* is a more lenient version of Ghose that allows compounds with molecular weights up to 500 Da
  2. HD hydrogen-bond donor; HA hydrogen-bond acceptor; MW molecular weight (Da); MR molar refractivity (m3 mol-1); Atoms atom count; RotB rotatable bonds; R rings; N, O, and X nitrogen, oxygen, and halogen atoms, respectively; PSA polar surface area (Å2); Sub substructure searching
