The NS2B-NS3 protease is a promising target for the development of drugs against dengue virus (DENV), West Nile virus (WNV) and related flaviviruses. We report the systematic variation of the peptide backbone of the two lead compounds Bz-Arg-Lys-d-Phg-NH2and Bz-Arg-Lys-d-Phg(OBn)-NH2. While inhibitory activity against WNV protease was generally decreased, the inhibitory potency against DENV protease could be conserved and increased in several peptidomimetics, particularly in those containing a (NMe)arginine fragment or anN-terminal α-keto amide. Methylation at the α-position of theC-terminal phenylglycine led to a 6-fold higher potency against DENV protease. Peptidomimetics with modified backbone showed increased resistance against hydrolytic attack by trypsin and α-chymotrypsin.
