EU-OPENSCREEN´s Compound Collections

With EU-OPENSCREEN´s unique compound collections you can explore the chemical space and target biology with Europe´s only open-access chemical biology infrastructure. Our main library, the European Chemical Biology Library (ECBL), consists of about 100,000 compounds with unbiased chemical diversity, designed by five academic computational chemistry groups, to which we will add over the next years a growing number of compounds collected from European chemists.

The compound collections can be used in high-throughput screening assays at any of our EU-OPENSCREEN screening partner sites.

All compounds in our libraries will be characterised in a panel of non-target specific bioprofiling assays (read more here), covering physicochemical and antimicrobial properties as well as potential cellular cytotoxicity.
