Rezumat

The investigation of influence of the molecular structure of different organic compounds on acute, developmental toxicity, mutagenicity has been carried out with the usage of 2D simplex representation of molecular structure and Support Vector Machine (SVM), Random Forest (RF), Gradient Boosting Machine (GBM), Partial Least Squares (PLS). Suitable QSAR (Quantitative Structure - Activity Relationships) models were obtained. The study was focused on QSAR model interpretation. The aim of the study was to develop a set of structural fragments that steadily increase various types of toxicity. The interpretation allowed to detail the molecular environment of known toxicophors and to propose new fragments.
