ePharmer: An integrated and graphical software for pharmacophore-based virtual screening.

Area of Science:

• Computational chemistry
• Drug discovery
• Bioinformatics

Background:

• Pharmacophore-based virtual screening (VS) is crucial for drug design, especially for targets with unknown structures.
• Existing software lacks integrated methods and user-friendly interfaces.

Purpose of the Study:

• To develop a stand-alone, integrated, graphical software for pharmacophore-based VS named ePharmer.
• To enhance the efficiency and accessibility of virtual screening for drug design.

Main Methods:

• Integrated ligand-based and structure-based pharmacophore generation.
• Developed a layered architecture (computing, integration, visualization) with a graphical user interface.
• Included metabolite prediction for experimental preselection.

Main Results:

• ePharmer provides a user-friendly interface for pharmacophore modeling, analysis, and VS.
• The software integrates diverse computational methods for efficient drug design.
• Experimental results confirmed ePharmer's computational capability, usability, and performance.

Conclusions:

• ePharmer offers a comprehensive and user-friendly solution for pharmacophore-based virtual screening.
• The software is suitable for both professional researchers and non-expert users.
• ePharmer is expected to accelerate the drug discovery process.
