Pharmacogenomic Knowledge Graph Augmentation for Graph Neural Network-Based Drug-Drug Interaction Prediction
Researchers have developed a method to enhance drug-drug interaction (DDI) prediction using Graph Neural Networks (GNNs) by incorporating pharmacogenomic data. This approach augments molecular structure information with details about drug metabolism pathways, specifically focusing on cytochrome P450 enzymes. The study found that this knowledge graph augmentation significantly improves DDI classification accuracy, particularly for interactions mediated by CYP2C9, though it did not overcome inherent limitations in predicting interactions for entirely new drugs.
