    Bioisostere TK

    Bioisostere TK provides functionalities for bioisosteric analog generation with fragment replacement. It involves replacing a portion of a lead compound with fragments that have similar shape and electrostatics but with potentially novel connectivity and chemistry.

    The toolkit centers around fragment-based 3D modeling tools, including fragment creation, fragment conformer generation, fragment alignment, and fragment replacement. Bioisostere TK leverages OpenEye's advanced molecular similarity tools based on shape, chemical features, and electrostatics, and brings those to fragment based modeling.

    Bioisostere TK provides level access similar to the existing BROOD and CHOMP applications.

    Bioisostere TK fragment overlay between a reference and a fit fragment, based on shape and color. The attachment points in both the reference and fit fragments are marked in purple. The fragment overlay highlights how special attention is paid to the overlay of the attachment points.

    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.
