Toxicity assessment and WoE

Digital toxicity assessment

Modern computer-based methods of toxicology and safety assessment are built on the assumption that there is a correlation between the chemical structure of a compound and its properties, including biological activity. Computer methods are becoming an increasingly important tool offering both financial and business benefits. They enable significant cost reduction resulting from greater efficiency – large sets of substances can be analyzed in a shorter time. Moreover, alternative methods fulfill the condition described in the REACH Regulation (EC 1907/2006) related to the reduction of unnecessary animal testing.

The experts at QSAR Lab have years of experience in computer toxicology, including the utilization of Quantitative Structure-Activity Relationship (QSAR) methods and Read-Across (RA) for predicting the properties required for the registration of chemical substances and nanomaterials.

The QSAR Lab's offer in the field of computer toxicology includes:

  • Analysis using computer methods to estimate biological activity and/or properties of a chemical compound/(nano)material, along with the preparation of documentation for the conducted analysis that complies with REACH requirements.
  • Support for R&D projects:
    – Expert consultations to precisely identify research problems and assistance related to the use of computer methods in the presented projects
    – Subcontracting of R&D tasks.
  • Conducting the weight of evidence process for assessing virtually any in vitro and in vivo toxicity endpoint.
  • Support for substance registration processes according to the REACH regulation through computer-based prediction of properties described in Annexes VII-X.
