Advanced Pharmacophore Modeling. LigandScout is a fully integrated platform for accurate virtual screening based on 3D chemical feature pharmacophore models. It offers seamless workflows, starting both from ligand- and structure based pharmacophore modeling, and includes novel high performance alignment algorithms for outstanding prediction quality with unprecedented screening speed.

Additionally, we have included user-friendly screening analysis tools, including the automated generation of ROC curves for performance assessments. All functions are accessible through a well elaborated graphic user interface that reflects our years of experience in creation of the most user-friendly pharmacophore modeling tools. The algorithms are scientifically validated and based on our well-established knowledge in pharmacophore research, while the software corresponds to state-of-the-art information technology.

LigandScout Features:
