Molecular descriptors were calculated with RDKit version 2018.09.1.

  • RoF = Lipinski's rule of five (number of violations).
  • LogP = Log of partition coefficient.
  • TPSA = topological polar surface area.
  • HBA = number of hydrogen bond acceptor.
  • HBD = number of hydrogen bond donor.
  • NRB = Number of rotatable bonds.

Considering all PKIs, to be prioritized a compound could:

  • Have a molecular weight (MW) between 314 and 613 Da (average of 463.4)
  • Have a ClogP (calculated with RDKit) between 0.7 and 6.3 (average of 3.5)
  • Contain between 0 and 4 hydrogen bond donors (HBD) (average of 2.2)
  • Contain between 3 and 10 hydrogen bond acceptors (HBA) (average of 6.4)
  • Have a topological polar surface area (TPSA) between 55 and 138 Å2 (average of 96.6)
  • Contain between 1 and 11 rotatable bonds (NRB) (average of 6.0)
  • Contain a number of aromatic rings (NAR) between 1 and 5 (average of 3.4)
  • Contain a number of chiral atoms (NCA) between 0 and 2 (average of 0.5)

The following inhibitors have been excluded from PKIDB because they have no available structure:
