Background:

• Current pharmacophore-based virtual screening (VS) software lacks interactive capabilities and intuitive processes.
• Limitations in existing VS tools hinder efficient exploration of molecular interactions and binding poses.

Purpose of the Study:

• To develop VRPharmer, a novel tool for performing the entire virtual screening workflow within virtual reality (VR) environments.
• To enhance user interaction and immersion during molecular structure observation and computation process perception.
• To provide advanced features for interactive screening and pharmacophore model refinement.

Main Methods:

• Implementation of a novel virtual reality environment for virtual screening.
• Development of interactive screening modes (OPT and SCORE modes) for pose exploration.
• Integration of editable pharmacophore models for feature analysis and result refinement.
• Improvement of molecular rendering algorithms for precise molecular representations.

Main Results:

• VRPharmer enables users to interactively perceive computational processes and immersively observe molecular structures.
• The SCORE mode allows for free exploration of optimal binding poses.
• Editable pharmacophore models facilitate the study of feature impacts and screening refinement.
• Enhanced molecular rendering ensures precise visualization of molecular details.

Conclusions:

• VRPharmer offers an innovative and interactive approach to virtual screening in drug discovery.
• The tool enhances the understanding of molecular interactions through immersive VR experiences.
• VRPharmer provides a more intuitive and efficient platform for virtual screening workflows.
