5IDK - PubMed Abstract: 
A thousand-fold affinity gain is achieved by introduction of a C-terminal boronic acid moiety into dipeptidic inhibitors of the Zika, West Nile, and dengue virus proteases. The resulting compounds have K i values in the two-digit nanomolar range, are not cytotoxic, and inhibit virus replication ...
