    The computer automated structure evaluation program (CASE) now performs quantitative structure-activity relationships (QSAR) automatically. This method accurately predicts the carcinogenicity of chemical compounds like polycyclic aromatic hydrocarbons and N-nitrosamines.

    Area of Science:

    • Computational chemistry
    • Toxicology
    • Medicinal chemistry

    Background:

    • Quantitative structure-activity relationships (QSAR) are crucial for predicting chemical toxicity.
    • Traditional QSAR methods can be labor-intensive and time-consuming.

    Purpose of the Study:

    • To extend the Computer Automated Structure Evaluation (CASE) program for automated QSAR analysis.
    • To apply the automated CASE-QSAR approach to predict the carcinogenicity of chemical compounds.

    Main Methods:

    • Utilized the CASE program for automated structure evaluation.
    • Developed and applied automatic quantitative structure-activity relationship (QSAR) models.
    • Tested the models on polycyclic aromatic hydrocarbons and N-nitrosamines.
