A web-based 3D-database pharmacophore searching tool for drug discovery

Area of Science:

• Computational chemistry
• Drug discovery
• cheminformatics

Background:

• Three-dimensional (3D) pharmacophore searching is crucial for identifying novel drug lead compounds.
• Existing commercial tools are often standalone, requiring local databases and limiting accessibility.
• The internet offers a platform for developing accessible, multiuser application distribution.

Purpose of the Study:

• To develop a Web-based tool for 3D-database pharmacophore searching.
• To implement both rigid and conformationally flexible search methods.
• To provide an accessible alternative to commercial, standalone software.

Main Methods:

• Development of a server-client Web architecture for the 3D pharmacophore search tool.
• Implementation of rigid pharmacophore searching algorithms.
• Implementation of conformationally flexible pharmacophore searching algorithms.

Main Results:

• Rigid pharmacophore searches (3- and 4-center) on 50,000 compounds completed in under 10 minutes.
• Flexible 3D-pharmacophore searches on 50,000 compounds took 1-few hours.
• Search results demonstrated comparability to commercial software outcomes.

Conclusions:

• The developed Web-based tool offers an effective and accessible method for 3D-database pharmacophore searching.
• This tool facilitates drug discovery by enabling efficient searching of compound libraries via the internet.
• The system is expected to be valuable for researchers engaged in computational drug design and discovery.
