Ontological approach to the knowledge systematization of a toxic process and toxic course representation framework...

Area of Science:

• Pharmacology
• Toxicology
• Bioinformatics

Background:

• Drug development is frequently hindered by toxicity, necessitating clear understanding of toxic mechanisms.
• Drug-induced liver injury (DILI) is complex, posing significant challenges for drug safety management.
• Existing knowledge on hepatotoxicity is fragmented, requiring a systematic approach for effective risk assessment.

Purpose of the Study:

• To develop a structured knowledge system for understanding drug toxicity mechanisms, focusing on hepatotoxicity.
• To create a toxic process ontology (TXPO) for consistent and unambiguous representation of toxic pathways.
• To build the TOXPILOT system for interpreting and visualizing toxicity mechanisms to aid drug safety.

Main Methods:

• An ontological approach was employed to construct the toxic process ontology (TXPO).
• Semantic web technologies were utilized to develop the TOXPILOT knowledge system.
• The system integrates and visualizes knowledge on toxic processes for drug safety applications.

Main Results:

• The toxic process ontology (TXPO) was successfully constructed, systematizing knowledge on hepatotoxic courses.
• The TOXPILOT system was developed, enabling interpretation and visualization of drug toxicity mechanisms.
• The system facilitates bridging basic science and clinical medicine for enhanced drug safety management.

Conclusions:

• The TXPO and TOXPILOT system offer a novel approach to understanding and managing drug toxicity, particularly hepatotoxicity.
• This ontological framework enhances drug safety evaluation by providing a consistent and interpretable view of toxic mechanisms.
• The developed system has the potential to significantly contribute to safer drug development and clinical application.
