  Drug safety is one of the key issues in the future realization of precision medicine.However,the molecular basis of the adverse drug reactions (ADRs) has not been fully understood yet.To complement this gap,we constructed the first comprehensive ADR ontology knowledgebase in the world,namely ADReCS,to provide not only ADR standardization but also hierarchical classification of ADR terms.Upon this database,we carried out large-scale statistical analyses for systematical characterization of ADRs from three aspects: indication,drug structure and target profile.We observed that drugs are prone to inducing ADRs in the same organ systems as that of their indications.Such propensity suggests that many ADRs likely have the similar molecular basis as what the drugs exert their therapeutic effects.Further drug-drug interaction network analysis based on ADR profile hints novel indications of current marketing drugs.To illustrate the impact of chemical structure on ADRs,we demonstrated an association analysis between chemical substructures (fingerprints) and their ADR profiles.A list of "good" and "bad" scaffolds were identified that can serve as an indicator in evaluating drug safety or guiding fine drug design for precision medicine.In summary,we found some general rules underlying ADRs.These rules provide clues for mechanistic investigation of ADRs,and furthermore,for rapid drug safety assessment in early drug discovery stage.
