Discovery of small molecule inhibitors of protein-protein interactions (PPIs) has been limited due to technological hurdles. Here we present the discovery of small molecule (MW< 500 Da) inhibitors of PPIs with IC50 in the μM range from a 2 million compound DNA-encoded chemical library. The screening of the library was performed using a recently developed homogenous binding assay. This format avoids protein target denaturation and matrix binding artifacts associated with conventional heterogeneous binding assays. The screening process relies on target binding only and not on functionality i.e. inhibition of PPI. However, interestingly, the majority of binders discovered are inhibitors of the PPI. Could this indicate that most binders are homing to the so called protein hotspots when the protein target is in native confirmations?
