    Zap TK

    Zap TK produces Poisson-Boltzmann electrostatic potentials [1] and, from them, biologically interesting properties including solvent transfer energies, binding energies, pKa shifts, solvent forces, electrostatic descriptors, surface potentials and effective dielectric constants. Zap TK works well for small molecules, proteins and macromolecular ensembles [2]. Unique to Zap TK is a dielectric function based on atom-centered Gaussians [3], which avoids the pitfalls of discrete dielectric constants.

    In a study of LCK kinase inhibitors, Zap TK was used to analyze the ligands solvent-exposed portions, simultaneously optimizing the solubility and binding affinity. In another study, Zap TK was used for high-throughput MM-PBSA calculations of relative binding free energies [4].

    The OpenEye Toolkit Ecosystem

    Modeling

    The Modeling suite of toolkits provides the core functionality underlying OpenEye's defining principle that shape & electrostatics are the two fundamental descriptors determining intermolecular interactions. Many of the toolkits in the Modeling suite are directly associated with specific OpenEye applications and can, therefore, be used to create new or extend existing functionality associated with those applications.

    • FastROCS™ TK Real-time shape similarity for virtual screening, lead hopping & shape clustering
    • OEDocking TK Molecular docking and scoring
    • Omega TK Conformer generation
    • Shape TK 3D shape description, optimization, and overlap
    • SiteHopper TK Rapid Comparison of Protein Binding Sites
    • Spicoli TK Surface generation, manipulation, and interrogation
    • Spruce TK Protein preparation and modeling
