| Outline of Final Research Achievements |
In this study, a novel method to predict drug adverse reactions (ADRs) based on machine leaning of small molecule-protein interaction profile was developed. At first, interactions between a compound and 329 proteins were predicted using molecular fingerprints. Then, the random forests models to predict 129 ADRs registered in SIDER2 drug side effect database were built based on the 329-dimensional interaction profile. Leave-cluster-out validation showed that the proposed method could maintain higher accuracy for compounds with low structural similarity to training data than the conventional prediction models directly using molecular fingerprint.
