    Self-consistent solvation energy contribution calculation for protein-ligand complexes

    Solvation energy is a major contribution to a ligand binding energy and is the interaction pretty much responsible for binding selectivity. Actual calculation of the solvation energy requires a method valid both for small molecule ligands and large proteins (and protein-ligand complexes). Calculation of the...

    Protein Flexibility and False Positives detection.

    Standard hit identification procedure with QUANTUM software implies screening of a large compound library against a given protein target. An example of such procedure for a small set of compounds with known activities is discussed in another blog entry. Let us show first that a...

    QUANTUM free energy vs. statistical scoring functions

    QUANTUM employs quantum mechanics, thermodynamics, and an advanced continuous water model for solvation effects to calculate ligands binding affinities. This approach differs dramatically from scoring functions that are commonly used for binding affinity predictions. By including the entropy and aqueous electrostatics contributions in to the...
