Biocides

Our services for biocides

  • Use of in silico predictions in a weight of evidence approach.

  • (Q)SAR and read-across methods for regulatory submissions.

  • In silico methods for toxicological profiling.

  • Toxicity flags for prioritization of testing.

Tools that we employ are:

  • Leadscope Model Applier

  • Lhasa (Derek and Sarah)

  • Other (VEGA/OECD QSAR Toolbox/T.E.S.T./Toxtree)

In Silico Toxicology

  • In silico toxicology (also referred to as computational toxicology) aims at predicting toxicity generally from chemical structure.

  • In silico toxicology includes category formation (grouping) and read-across, Structure-Activity Relationship (SAR), Quantitative Structure-Activity Relationship (QSAR), and Expert Systems.

  • In silico toxicology methods play a crucial role to generating additional information for complementing and ultimately enhancing or supporting a risk assessment, including an understanding of the structural and/or mechanistic basis that may contribute ideas for the rational design of new chemicals, development of a testing strategy or an overall weight-of-evidence evaluation.
