Abstract
OncoLogic® is a software program able to screen chemical compounds for toxicological effects. The software predicts the potential carcinogenicity of chemicals by applying rules of structure activity relationship (SAR) analysis. To validate the predictivity of OncoLogic® (Version 7.0), 123 compounds tested with the long-term carcinogenicity bioassay on rodents were extracted from the ISSCAN database and were analyzed. The concordance between the OncoLogic® SAR analysis and the bioassay results was high. To better understand the strength of the SAR science in OncoLogic®, we investigated the influence of a select group of modulating factors on the predictions by the structural alerts.
期刊介绍：
Journal of Environmental Science and Health, Part C: Environmental Carcinogenesis and Ecotoxicology Reviews aims at rapid publication of reviews on important subjects in various areas of environmental toxicology, health and carcinogenesis. Among the subjects covered are risk assessments of chemicals including nanomaterials and physical agents of environmental significance, harmful organisms found in the environment and toxic agents they produce, and food and drugs as environmental factors. It includes basic research, methodology, host susceptibility, mechanistic studies, theoretical modeling, environmental and geotechnical engineering, and environmental protection. Submission to this journal is primarily on an invitational basis. All submissions should be made through the Editorial Manager site, and are subject to peer review by independent, anonymous expert referees. Please review the instructions for authors for manuscript submission guidance.
