Library proposers

What's in it for you?

Any researcher in Europe had the chance to submit a chemical library proposal and benefit from: 

  • Monetary incentives
  • Educational opportunities for your research group members
  • Insights into industry-standard processes

Sufficient library proposals have now been received to enable completion of the production of the Joint European Compound Library. The European Lead Factory thanks everybody for their contributions.

In case the proposal lead to the production of at least 50 compounds by one of the entitled European Lead Factory contract-research partners for addition into the Joint European Compound Library (JECL) and you were working for a university, institute or small and medium-sized enterprise, you would receive a monetary reward up to 5000 Euros (see table). In addition, you will see your library converted into lead molecules synthesised with real potential to support future drug discovery.

More information about this crowdsourcing action can be found under How to submit.
