Nexus DEREK
DEREK predicts the Ames Mutagenicity potential of a substance based on the triggered structural alerts for this endpoint. The report also provides detailed information about each triggered alert and also the strength of the reliability in prediction.
OECD QSAR Toolbox v4.2
The latest version of the OECD QSAR Toolbox facilitates the profiling of a query substance based on the following Ames Mutagenicity relevant profilers incorporated into its interface:
Profilers
DNA alerts for AMES by OASIS

Remarks / Additional Comments (optional): No remarks or comments. - Executive summary:
Introduction.Multiple Quantitative Structure Activity Relationship (QSAR) models were used to predict the Ames mutagenicity of the test item Methyl 2-[(2-methylundecylidene)amino]benzoate. These QSAR models has been designed to be used for regulatory purposes and based on the QSAR results, this report predicts the consensus endpoint value which would be expected when testing the substance under experimental conditions in a laboratory following the OECD Guideline for Testing of chemcials No. 471: Bacterial Reverse Mutation Test.
Methods.The purpose of the in silico study was to predict the Ames Mutagenicity of the test item Methyl 2-[(2- methylundecylidene)amino]benzoate. This prediction was performed using the following QSAR models:
· Nexus DEREK v6.0.1
· OECD QSAR Toolbox v4.2 (profiling results)
· Danish QSAR Database
The final consensus result for Ames mutagenicity was derived by applying a consensus method on the reliable results derived for individual models.
Results.
Based on multiple QSAR models applied, Methyl 2-[(2-methylundecylidene)amino]benzoate was predicted as non-mutagenic for the Ames mutagenicity test.
The final QSAR result can be associated with a Klimisch score:K2
