ForthTox is an independent, toxicological consultancy working in pharmaceutical and chemical development; we are located in Scotland. We offer two proprietary in silico models for prediction of toxicity: Leadscope and Derek Nexus and use other software, such as T.E.S.T., CAESAR and ToxTree as appropriate; we also have a licence for METEOR for prediction of metabolism, allowing cross-checking of metabolites for toxicity. The results of in silico evaluation are validated, where appropriate, by reference to reports for closely related substances or by read across to groups of related chemicals, depending on context and information availability. We have extensive experience with in silico and in cerebro evaluations and our reports have been submitted to, and accepted by, major authorities including FDA and EMA.
