A novel scoring function, BHB (buriedness, hydrogen bonding, and binding energy), rapidly ranks potential drug ligands. This method significantly improves ligand identification, showing up to 12 times better enrichment than GOLD.

Area of Science:

  • Computational chemistry
  • Drug discovery
  • Molecular modeling

Background:

  • Accurate scoring functions are crucial for virtual screening in drug discovery.
  • Existing methods may lack efficiency or accuracy in ranking potential ligands.
  • Knowledge-based approaches can leverage structural and energetic information.

Purpose of the Study:

  • To develop a novel, knowledge-based scoring function for rapid ligand ranking.
  • To improve the efficiency and accuracy of virtual screening processes.
  • To provide a tool that enhances the identification of high-affinity ligands.

Main Methods:

  • Developed the BHB (buriedness, hydrogen bonding, and binding energy) scoring function.
  • Utilized receptor buriedness, hydrogen bond formation potential, and approximate binding energy calculations.

  • Derived descriptors from 3D structures of ligand-receptor complexes or unbound receptors with known active ligands.

    • Main Results:

    • The BHB scoring function demonstrated significant performance improvements.
    • Achieved up to 12 times better enrichment compared to the GOLD docking program.
    • Successfully ranked ligands based on key molecular interaction descriptors.

    Conclusions:

    • The BHB scoring function offers a rapid and effective method for ligand ranking.
    • This approach enhances the hit identification rate in virtual screening.
    • The method provides a valuable tool for accelerating drug discovery pipelines.
