The European Chemical Biology Symposium (ECBS) is our flagship event and brings together Chemical Biologists from all parts of Europe and overseas to present and discuss the latest achievements in cutting edge chemical sciences. The ECBS is jointly organised every two years by EU-OPENSCREEN and the EuChemS Division of Chemistry for Life Sciences.

EU-OPENSCREEN organises the 9th edition of its biennial scientific meeting, the European Chemical Biology Symposium (ECBS) on October 6–9, 2025, at the Sorbonne Université in Paris, France.
Ten years after the ICBS/ECBS2015 in Berlin, the last joint meeting with the International Chemical Biology Society (ICBS), the ICBS returns to Europe.
The upcoming ICBS/ECBS2025 is jointly organised by EU-OPENSCREEN, the European Chemical Society (EuChemS Division of Chemistry in Life Sciences), International Chemical Biology Society (ICBS) and the Chemical Biology Division of the French Chemical Society (SCF-ChemBio).
The main theme of the ICBS/ECBS2025 is "Approaching biology through chemistry" and several exciting topics will be addressed during the sessions. The conference brings together though leaders in the field and young minds from the global chemical biology community will discuss new approached to addressing the unmet challenges in the interface of chemistry and biology.

On behalf of the Scientific and Organizing Committees, it is our pleasure to invite you to the virtual European Chemical Biology Symposium (ECBS) 2021, which is jointly organised by EU-OPENSCREEN and the EuChemS Division of Chemistry for Life Sciences .The meeting builds on the success of the 6th ECBS/LS-EuChemS in Madrid in 2019, the 5th ECBS in Budapest 2017 and the ICBS/ECBS joint meeting in Berlin in 2015.
The virtual ECBS 2021 brings together scientists from Europe and overseas to present and discuss their latest achievements in cutting edge chemical sciences at the interface with biology and medicine, ranging from new therapeutic approaches to resistant pathogens and viral infections (special session on COVID19 research), to targeting of proteasome and protein aggregation, natural products, artificial intelligence in drug discovery, nanostructured biomaterials, synthetic biology, glycochemistry and biology, chemistry of life origin.
We encourage young researchers to present their work at the meeting (oral & flash presentations will be selected from submitted abstracts), and embrace the exciting developments currently happening in chemical biology.
The conference is split over 3 days – May 26th until May 28th starting with an opening lecture from Herbert Waldmann (Max-Planck Insitute of Molecular Physiology). The ECBS2021 further includes 9 sessions on
and a dedicated evening session on Covid-19 research activities.
Abstract submission deadline: 31/03/2021
Free registration deadline: 31/04/2021

On behalf of the Scientific and Organizing Committees, we were pleased to welcome participants to Madrid for the 6th ECBS/LS‑EuChemS meeting. The event brought together the 6th European Chemical Biology Symposium and the meeting of the EuChemS Division Chemistry in Life Sciences (LS‑EuChemS), jointly organized by EuChemS and EU‑OPENSCREEN. It followed the successful joint ICBS/ECBS meeting in Berlin (2015) and the 5th ECBS in Budapest (2017).
Chemical biologists from across Europe and overseas gathered to present and discuss the latest achievements in cutting‑edge chemical sciences. The joint meeting brought together researchers working in organic and biological chemistry, protein biotechnology, computational biology, protocells, machine learning, bacterial resistance, drug discovery, synthetic biology, biomedical materials and chemical glycobiology.

The EU‑OPENSCREEN community met in Budapest from July 2–4 during the 5th European Chemical Biology Symposium. The event brought together more than 100 participants from 22 countries across Europe, Asia and the Americas, featuring three keynote lectures, eight plenary talks, nine oral presentations, four short talks and over 50 posters.
The keynote speakers offered complementary perspectives on the field: Herbert Waldmann (Max Planck Institute of Molecular Physiology, Dortmund) discussed natural‑product‑inspired small‑molecule library design; Stefan Knapp (Goethe University Frankfurt) highlighted strategies for validating emerging disease targets; and John P. Overington (Medicines Discovery Catapult, UK) addressed the development of chemical biology databases and the challenges of large‑scale data mining.

The second European Chemical Biology Symposium focused on key topics including protein modifications, molecular chaperones, and stem cell biology. The meeting brought together researchers from a wide range of disciplines—chemistry, biology, pharmacology, chemoinformatics, and bioinformatics—who shared a common interest in the interdisciplinary field of chemical biology.
The symposium provided an excellent platform for scientific exchange, offering participants numerous opportunities to discuss ongoing research, explore emerging directions, and foster new collaborations within the international community.
Sessions included:
Protein Modifications
Chemical Biology in Europe and Beyond
Chemical Chaperones and Protein Aggregation
New Challenges and Avenues
Stem Cell Biology
