In this study, we have established a three-tier QSAR modeling strategy for estimating the EIP of chemicals for the use of pharmaceutical industry and regulatory agencies. Accordingly, a qualitative (binary classification: irritating, non-irritating), semi-quantitative (four-category classification), and quantitative (regression) QSAR models employing the SDT, DTF, and DTB methods were developed for predicting the EIP of chemicals in accordance with the OECD guidelines. Structural features of chemicals responsible for eye irritation were extracted and used in QSAR analysis. The external predictive power of the developed QSAR models were evaluated through the internal and external validation procedures recommended in QSAR literature. In test data, the two and four category classification QSAR models (DTF, DTB) rendered accuracy of >93%, while the regression QSAR models (DTF, DTB) yielded correlation (R(2)) of >0.92 between the measured and predicted EIPs. Values of various statistical validation coefficients derived for the test data were above their respective threshold limits (except rm(2) in DTF), thus put a high confidence in this analysis. The applicability domain of the constructed QSAR models were defined using the descriptors range and leverage approaches. The QSAR models in this study performed better than any of the previous studies. The results suggest that the developed QSAR models can reliably predict the EIP of diverse chemicals and can be useful tools for screening of candidate molecules in the drug development process.","is_dataset_classified":null,"base_score":2.8903717578961645,"endowment":2.8903717578961645,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"27018829","pmcid":null,"openalex_id":"https://openalex.org/W2309296013","authors":[],"funders":[],"total_grants":0,"fwci":1.3041,"citation_percentile":0.82022806,"influential_citations":0,"citation_trend":[{"year":2016,"count":1},{"year":2017,"count":3},{"year":2020,"count":2},{"year":2021,"count":4},{"year":2022,"count":1},{"year":2023,"count":3},{"year":2024,"count":1},{"year":2025,"count":1},{"year":2026,"count":1}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0273230016300587?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0273230016300587?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.yrtph.2016.03.014","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/27018829","host_type":"repository"}],"fields_of_study":["Computational Drug Discovery Methods","Animal testing and alternatives","Biochemical and Structural Characterization","Animal Testing Alternatives","Animals","Data Mining","Databases, Factual","Eye Diseases","Irritants","Models, Molecular","Models, Statistical","Molecular Structure","Quantitative Structure-Activity Relationship","Rabbits","Regression Analysis","Risk Assessment","Toxicity Tests"],"mesh_terms":["Animals","Animal Testing Alternatives","Eye Diseases","Irritants","Models, Molecular","Rabbits","Regression Analysis","Models, Statistical","Molecular Structure","Databases, Factual","Risk Assessment","Toxicity Tests","Quantitative Structure-Activity Relationship","Data Mining"],"keywords":["Quantitative structure–activity relationship","Applicability domain","Eye irritation","Molecular descriptor","Leverage (statistics)","Computer science","Machine learning","Biochemical engineering","Artificial intelligence","Irritation","Engineering","structural diversity","structural features","Eye Irritation Potential","Regression Qsar","Qualitative And Semi-quantitative Qsar","Three-tier Strategy"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-19T13:15:20.980217Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
