Název: VSpipe-GUI, an Interactive Graphical User Interface for Virtual Screening and Hit Selection.
Autoři: Hussain, Rashid, Hackett, Andrew Scott, Álvarez-Carretero, Sandra, Tabernero, Lydia
Zdroj: International Journal of Molecular Sciences; Feb2024, Vol. 25 Issue 4, p2002, 16p
Témata: GRAPHICAL user interfaces, PYTHON programming language, HEPATITIS C virus, CHEMICAL libraries, SPATIAL filters
Abstrakt: Virtual screening of large chemical libraries is essential to support computer-aided drug development, providing a rapid and low-cost approach for further experimental validation. However, existing computational packages are often for specialised users or platform limited. Previously, we developed VSpipe, an open-source semi-automated pipeline for structure-based virtual screening. We have now improved and expanded the initial command-line version into an interactive graphical user interface: VSpipe-GUI, a cross-platform open-source Python toolkit functional in various operating systems (e.g., Linux distributions, Windows, and Mac OS X). The new implementation is more user-friendly and accessible, and considerably faster than the previous version when AutoDock Vina is used for docking. Importantly, we have introduced a new compound selection module (i.e., spatial filtering) that allows filtering of docked compounds based on specified features at the target binding site. We have tested the new VSpipe-GUI on the Hepatitis C Virus NS3 (HCV NS3) protease as the target protein. The pocket-based and interaction-based modes of the spatial filtering module showed efficient and specific selection of ligands from the virtual screening that interact with the HCV NS3 catalytic serine 139.
