Abstract:
The mosquito-borne West Nile virus (WNV) causes a wide range of symptoms ranging from fever to the often fatal viral encephalitis. To date, no vaccine or drug therapy is available. The trypsin-like WNV NS2B-NS3 protease is deemed a plausible drug target and was shown to be inhibited by bovine pancreatic trypsin inhibitor (BPTI), a 58-residue protein isolated from bovine lung. Herein, we report a protein truncation study that resulted in a novel 14-residue cyclic peptide with equipotent inhibitory activity to native BPTI. We believe our truncation strategy can be further applied in the development of peptide-based inhibitors targeting trypsin-like proteases.
