QSAR & Read-across predictions
Simply Predict applies a battery of recognized QSARs and Read-across tools to predict a wide range of Physicochemical, Human Health, Environmental and Ecotoxicological properties. If you intend to use predicted results to fulfill regulatory obligations, our regulatory experts can help with required documentation.

QSAR training courses adapted to your needs
QSAR & Read-across training for toxicologists
Key objectives:
Learn how to apply in silico toxicology models, generate reports and interpret reliability of the predicted results
Case studies covering multiple toxicological endpoints including Skin Sensitisation, Ames Mutagenicity etc.
Battery of multiple in silico models covered including OECD QSAR Toolbox, Toxtree, VEGA etc.
Case studies designed to cover mono-constitutents, impurities, mixtures and UVCBs
Learn how to use in silico results in regulatory submissions: QMRF & QPRF reports
Next training sessions will be defined soon
Why choose Simply Predict?
Combined expertise
for a decisive strategy
Our QSAR experts identify and
run the most fit-for-purpose battery of models and our regulatory experts validate the strategy and conclusions.
100% non-conflicted and
non-biased solutions
We do not develop any in-house prediction models or tools or have any preferred list of models or developers to work with! We propose curated solutions from a wide pool of in silico models on a case by case basis.
Because
time matters...
All standard queries are assured a response within 2 working days.
