The European Union Reference Laboratory for Alternatives to Animal Testing (EURL ECVAM) is part of the European Commission’s Joint Research Centre (JRC) located in Ispra, Italy. The JRC carries out research to provide independent scientific advice and support to EU policy. EURL ECVAM promotes the Replacement, Reduction and Refinement (Three Rs) of animal procedures. Alternatives to animal testing in toxicology include computational methods such as Quantitative Structure-Activity Relationship (QSAR) models. The point of contact for questions to the laboratory and its computational activities is jrc-computox [at] ec.europa.eu

The QSAR models listed here are mostly collected from the JRC QSAR Model Database (see the collection below) to help to identify valid QSARs for regulatory purposes.

Disclaimer:

All QSARs listed in the collections are the sole responsibility of the original developers. In case of questions about these QSARs, interested parties are kindly asked to contact the original developers.

Published: Geven Piir (2020-03-13)

Abstract: All compounds are considered to act by polar narcosis. This is well established for non-reactive compounds. Acute lethality is brought about by accumulation in cellular membranes causing their disruption and ultimately death of the organism. The ability of the compound to accumulate in a cellular membrane is thought to be related to its intrinsic hydrophobicity. ...

Abstract: The purpose of the analyses presented in this report was to contribute to an evaluation of the possibility of using QSAR predictions for regulatory purposes. To this end QSAR predictions were compared with SIDS test data. Furthermore, the models were also assessed according to the extent to which they meet OECD principles for QSAR validation (OECD ENV/JM/Mon ...

Abstract: Abstract Vertebrate testing under the European Union's regulation on Registration, Evaluation, Authorisation and Restriction of Chemical substances (REACH) is discouraged, and the use of alternative nontesting approaches such as quantitative structure?activity relationships (QSARs) is encouraged. However, robust QSARs predicting chronic ecotoxicity of organic ...

Published: Geven Piir (2020-03-03)

Abstract: Chemically reactive, α, β-unsaturated carbonyl compounds are common environmental pollutants able to produce a wide range of adverse effects, including, e.g. mutagenicity. This toxic property can often be related to chemical structure, in particular to specific molecular substructures or fragments (alerts), which can then be used in specialized software or ...

Abstract: Aldehydes are widespread environmental and industrial compounds, able to stimulate a range of adverse health effects (e.g., general toxicity, allergenic reactions, mutagenicity, and carcinogenicity). We have previously presented quantitative structure–activity relationships (QSARs) for the genotoxicity of simple and α,β‐unsaturated aliphatic aldehydes. In this ...

Abstract: The risk of the presence of haloacetic acids in drinking water as chlorination by-products and the shortage of experimental mutagenicity data for most of them requires a research work. This paper describes a QSAR model to predict direct mutagenicity for these chemicals. The model, able to describe more than 90% of the variance in the experimental activity, was ...

Abstract: (Q)SAR models can be used to reduce animal testing as well as to minimise the testing costs. In particular, classification models have been widely used for estimating endpoints with binary activity. The aim of the present study was to develop and validate a classification-based quantitative structure-activity relationship (QSAR) model for endocrine disruption, ...

Abstract: To comply with the REACH (Registration, Evaluation, Authorisation and restriction of Chemicals) regulations, the generation of chronic fish toxicity data is required for chemicals produced or imported within or into the EU in quantities greater than 100 tonnes per year. This comes at a great cost to industry and consumers alike and requires the sacrifice of ...
