Alternative methods
Minor organisms (bacteria, algae or fungi)
“In vitro" techniques (cell cultures, tissue portions)
“In silico" (computational) methods

*AEs = Adverse Effects
** i ) In silico models are completely acceptable if following the OECD principles
ii ) A limited liste of in vitro assays have been developed and are accepted by regulatory authorities
iii ) In vivo models are acceptable when other alternatives are not possible/reliable, and they are completely banned in EU in specific cases such as cosmetics

• Compiled Datasets (3) with > 5000 compounds with ED activity
• Computational models to predict AhR antagonism. One paper submitted (waiting foracceptance), two papers in process.
• Collaboration with laboratories in the EU specialized in the development of in vitroalternative methods in toxicology (GIGA-ULiège, QUB-Belfast).
• TA in several Masters programs (e.g. Master's Degree in Environmental Pollution, Toxicologyand Health).
• Participation in conferences on alternative methods in toxicology (ESTIV2018 – Berlin,CHEMCYS 2018 -Belgium)
Results and Outcomes

Impact on ProtoQSAR of EU projects
![Page 12: ProtoQSAR: Contributions, Impact and Challenges in the ... · Training of ESRs on chemoinformatics (QSAR model development) & modeling approaches (pharmacophores, docking, virtual](https://reader034.vdocument.in/reader034/viewer/2022050312/5f748fc79bb604705e6393d7/html5/thumbnails/12.jpg)
• ESRs have shared expertise with employees at ProtoQSAR allowing forcritical knowledge transfer
• Greater visibility of the company which has allowed for participations inother EU projects e.g. RISE, SEP, SMEi
• Collaborations in future projects with consortium members
Impact on ProtoQSAR
![Page 13: ProtoQSAR: Contributions, Impact and Challenges in the ... · Training of ESRs on chemoinformatics (QSAR model development) & modeling approaches (pharmacophores, docking, virtual](https://reader034.vdocument.in/reader034/viewer/2022050312/5f748fc79bb604705e6393d7/html5/thumbnails/13.jpg)
• Difficulty in attaining sufficient data for computational modeling in a timelymanner.
• Mobility issues with non-EU ESRs (e.g. VISAs).
• Specific issue in a SME: availability of time for educational purposes.
