Chemical Space Visualization for Compound Toxicity Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toxicity evaluation methods using computer-based in silico methods do not adequately consider the relationship between the position of a compound in a chemical space and its toxicity evaluation result, making it difficult to analyze and support users in evaluating compound toxicity.
Innovation Solution
An information processing apparatus and method that generates a display image mapping compounds onto a chemical space with distinguishable toxicity evaluation results, using feature amounts such as molar mass and lipophilicity as coordinate axes, and allows for interactive visualization and filtering of compounds based on their positions and evaluation results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If compounds are mapped onto chemical space using conventional methods, then the molecular structure information is visualized, but the relationship between compound position and toxicity evaluation results cannot be understood
Solution Approach 1:
The patent merges the chemical space visualization with toxicity evaluation results by superimposing toxicity information onto the existing chemical space map. This integration allows users to see both the molecular structure positioning and toxicity assessment in a single unified display, eliminating the need for separate analysis tools and preserving complete information without increasing system complexity.
Solution Approach 2:
The patent applies color coding to represent different toxicity evaluation results on the chemical space map. By assigning distinct colors or visual markers to compounds based on their toxicity levels, the system enables intuitive differentiation of toxicity states while maintaining the structural positioning information, thus preserving toxicity information without complicating the visualization interface.
2Loss of information
If detailed toxicity evaluation results are displayed for all compounds, then complete analysis information is provided, but the ease of understanding the relationship between position and toxicity is reduced
Solution Approach 1:
The patent implements local quality by providing detailed toxicity evaluation information only when users interact with specific compounds of interest. The system displays comprehensive toxicity data selectively for selected or highlighted compounds rather than overwhelming the user with all data at once. This approach preserves complete toxicity information while improving ease of operation by presenting details contextually based on user interaction.
3Ease of operation
If conventional chemical space mapping is used without toxicity integration, then the molecular structure visualization is maintained, but the support for toxicity evaluation is insufficient
Solution Approach 1:
The patent combines the chemical space mapping functionality with toxicity evaluation support by integrating toxicity data directly into the visualization. This merging allows the system to maintain its molecular structure visualization capabilities while simultaneously providing comprehensive toxicity evaluation support, eliminating the need for separate analysis processes and ensuring no toxicity information is lost.

AI summary
An information processing apparatus includes a processor, in which the processor is configured to generate a display image in which marks indicating a compound group including a target compound, which is a compound to be subjected to an toxicity evaluation, and a plurality of reference compounds, which are compounds to be compared with the target compound, are mapped onto a chemical space in which a plurality of feature amounts related to a molecular structure of a compound are set as coordinate axes, in which the marks are displayed such that a result of the toxicity evaluation for each of the compounds is distinguishable, and execute control of outputting the generated display image.
