Highly sensitive in vitro selections for DNA-linked synthetic small molecules with protein binding affinity and specificity.
We have developed in vitro selections for DNA-linked synthetic small molecules with protein binding affinity and specificity. These selections require only generally accessible equipment, offer high degrees of enrichment of active molecules from mixtures of predominantly inactive species, can be applied to a variety of unrelated proteins, and require approximately 108-fold less material than existing synthetic molecule screening methods. Iterating these selections multiplies the net enrichment of active molecules, enabling enormous overall enrichment factors exceeding 106 to be achieved. Further, the selections can be adapted to select for binding specificity in addition to binding affinity. The application of methods described in this work may play a key role in the discovery of desired molecules from DNA-templated synthetic libraries.
