dc.description.abstractA series of tripeptide aldehyde inhibitors were synthesized and their inhibitory effect against dengue virus type 2 (DENV2) and West Nile virus (WNV) NS3 protease was evaluated side by side with the aim to discover potent flaviviral protease inhibitors and to examine differences in specificity of the two proteases. The synthesized inhibitors feature a varied N-terminal cap group and side chain modifications of a P2-lysine residue. In general a much stronger inhibitory effect of the tripeptide inhibitors was observed toward WNV protease. The inhibitory concentrations against DENV2 protease were in the micromolar range while they were submicromolar against WNV. The data suggest that a P2-arginine shifts the specificity toward DENV2 protease while WNV protease favors a lysine in the P2 position. Peptides with an extended P2-lysine failed to inhibit DENV2 protease suggesting a size-constrained S2 pocket. Our results generally encourage the investigation of di- and tripeptide aldehydes as inhibitors of DENV and WNV protease.
