The VEGAHUB Platform: The Philosophy and the Tools

Area of Science:

• Computational toxicology
• Cheminformatics
• Environmental science

Background:

• VEGAHUB is a repository of freely available computational toxicology tools.
• The primary tool, VEGA QSAR, contains over 90 quantitative structure-activity relationship (QSAR) models for diverse toxicological and physicochemical endpoints.
• VEGAHUB offers additional tools beyond VEGA QSAR.

Purpose of the Study:

• To present the resources available in VEGAHUB.
• To explore the integration possibilities of different VEGAHUB tools.
• To highlight the application of VEGAHUB tools in general research and specific scenarios.

Main Methods:

• Utilizing VEGA QSAR software with over 90 quantitative structure-activity relationship (QSAR) models.
• Employing read-across and weight-of-evidence approaches.
• Integrating hazard and exposure data using specific tools for defined scenarios (e.g., cosmetic products).
• Prioritizing assessments by integrating results from 48 models.
• Critical assessment of predictions and associated documentation.

Main Results:

• VEGAHUB provides a comprehensive suite of tools for computational toxicology.
• Integration of multiple tools enables advanced analyses, including read-across and weight-of-evidence.
• Tools are applicable to predefined endpoints and general QSAR research.
• Examples demonstrate critical assessment of predictions, acknowledging potential uncertainty and conflicts.

Conclusions:

• VEGAHUB offers valuable, freely accessible resources for computational toxicology research and application.
• The platform supports integrated approaches to hazard and exposure assessment.
• Users are encouraged to critically evaluate predictions for reliable risk assessment.
