The molecular orbital theory describes the distribution of electrons in molecules in a manner similar to the distribution of electrons in atomic orbitals. The region of space in which a valence electron in a molecule is likely to be found is called a molecular orbital. Mathematically, the linear combination of atomic orbitals (LCAO) generates molecular orbitals. Combinations of in-phase atomic orbital wave functions result in regions with a high probability of electron density, while...

Area of Science:

  • Computational chemistry
  • Structural biology
  • Drug discovery

Background:

  • Molecular docking is crucial for identifying drug leads but often struggles with accurate binding affinity prediction.
  • Existing scoring functions show poor correlation with experimental binding data.
  • Multipose binding, where ligands adopt multiple conformations, is a known phenomenon in protein-ligand interactions.

Purpose of the Study:

  • To improve the accuracy of molecular docking by integrating a multipose binding concept into scoring functions.
  • To enhance the correlation between predicted and experimental binding affinities.
  • To assess the impact of multipose binding on virtual screening efficacy.

Main Methods:

  • A high-throughput molecular docking study was performed.
  • A multipose binding strategy was implemented by considering multiple ligand conformations in the scoring procedure.
  • The performance of the enhanced scoring scheme was evaluated against experimental binding affinity data.

Main Results:

  • The multipose binding concept generally improved the agreement between docking scores and experimental binding affinities.
  • The most significant improvements were observed for complexes involving large, flexible ligands and high binding affinities.
  • The study demonstrated the potential of multipose binding for more accurate binding affinity prediction.

Conclusions:

  • Incorporating multipose binding into molecular docking scoring functions can enhance prediction accuracy.
  • This approach shows particular benefit for complex protein-ligand systems.
  • Further refinement of selection criteria for docking solutions is needed for widespread application.
