VSpipe-GUI

VSpipe-GUI provides a graphical user interface for structure-based virtual screening and hit selection of large chemical libraries to support computer-aided drug development.

Key Features:

• Cross-platform compatibility: Functions in Linux distributions, Windows, and Mac OS X as a Python toolkit.
• Spatial filtering module: Filters docked compounds based on specified features at the target binding site, including pocket-based and interaction-based modes.
• AutoDock Vina integration: Performs molecular docking with considerably faster execution compared to the previous command-line version.

Scientific Applications:

• Computer-aided drug development: Provides rapid and low-cost virtual screening of large chemical libraries for further experimental validation.
• Protease target screening: Enables efficient and specific selection of ligands that interact with catalytic residues, as demonstrated on Hepatitis C Virus NS3 (HCV NS3) protease with catalytic serine 139.

Methodology:

Structure-based virtual screening using AutoDock Vina for molecular docking, with a spatial filtering module for compound selection based on binding site features.
