Laboratory of Toxicology of Faculty of Pharmacy of University of Porto:



The TOXI group has a long established expertise in in vitro and in vivo toxicology, and in chemical analysis in the ambit of toxicity mechanisms, toxicokinetics, forensic and clinical toxicology. We have been successfully developing studies for toxicokinetic and mechanistic clarification of several types of compounds contributing not only to the safety profiling of these substances, but also to the efficacy assessment of potentially pharmacologically active drugs. The TOXI achievements can be divided into 4 main topics: i) new treatment approaches for intoxications, ii) clarification of mechanisms of drug toxicity, iii) toxicity of drugs of abuse and iv) safety assessment of nanoparticles (NP).

The TOXI group intends to continue and improve the main areas of research for which a capital of experience and international recognition has already been acquired:

  • Develop toxicokinetic and mechanistic studies for an insight into the so-called legal drugs toxicity
  • Study interindividual factors governing the susceptibility towards the toxicity of drugs of abuse by using mixture toxicology models
  • Search for new antidotes, integrating the in silico data obtained by other group for candidate compounds with our in vitro and in vivo studies
  • Toxicological evaluation of nanomaterials for biomedical applications after their synthesis by other group 
  • Use metabolomic tools to dissect mechanisms of action and to find new and sensitive biomarkers of toxicity in the modern context of Systems Toxicology
  • Continue to devot a great effort to the refinement and replacement of in vivo by in vitro assays, especially in metabolic, bioavailability and mechanistic studies

Overall, it is our main objective to strengthen our most successfully implemented lines of research for which solid expertise exists and also to pursue the most innovative lines for which new collaborations will be established to acquire new expertise. It is also our goal to apply not only for nationally funded projects but also for transnational projects and integrate international networks especially in those areas that are considered a priority, such as is the case of nanotoxicology.
