A potential anti‐SARS drug has been developed by dynamic ligation screening (DLS), by which nucleophilic fragments are directed to the protein's active site by reversible reaction with an aldehyde inhibitor. Their inhibitory effect is detected by competition with a fluorogenic enzyme substrate. With this concept, low‐affinity fragments binding specifically to the active site are quickly identified in a functional enzyme assay.

The present invention relates to the identification of binder compounds for a certain target by a site-directed screening method, whereby the binding of a compound can be detected in a parallel detection assay. The invention also relates to the modification of these compounds as well as the use in a pharmaceutically acceptable form.
