Dengue and West Nile virus are rapidly spreading global pathogens for which no specific therapeutic treatments are available. One of the promising targets for drug discovery against dengue and other flaviviruses is the viral serine protease NS2B-NS3. We present the design, synthesis, and in vitro and cellular characterization of a novel chemotype of potent small-molecule non-peptidic dengue protease inhibitors derived from 4-benzyloxyphenylglycine. A newly developed luciferase-based DENV-2 protease reporter system in HeLa cells (DENV2proHeLa) was employed to determine the activity of the compounds in a cellular environment. Specificity and selectivity of the DENV2proHeLa system were confirmed by viral titer reduction assays. The compounds reach low micromolar to upper nanomolar inhibitory potency in cell-based assays, are selective against other serine proteases, and do not show relevant cytotoxicity. An extensive structure-activity relationship study provides a perspective for further drug development against flaviviral infections.

Chiral C2-symmetric bisoxazolines 1b-f and 2b,c, derived from 4′-O-alkylated R-4-hydroxyphenylglycine or S-tyrosine, were prepared. As intermediates, a series of chiral amino alcohols possessing substituted phenolic groups was prepared and fully characterized.
