The β-OG pocket is a cavity in the flavivirus envelope (E) protein that was identified by Proc. Natl. Acad. Sci. U.S.A.2003, 100, 6986 as a promising site for the design of antiviral agents that interfere with virus entry into the host cell. The availability of the X-ray crystal structure of the dengue virus (DENV) E protein provided an opportunity for in silico drug design efforts to identify candidate inhibitors. The present study was set up to explore whether it is possible to generate a novel class of molecules that are hybrids between two hit compounds that have been reported previously by ACS. Chem. Biol.2008, 3, 765 following an in silico screening effort against the DENV E protein. First, a library of twenty hybrid molecules were designed and synthesized to explore the feasibility of this strategy. Antiviral evaluation in a virus-cell-based assay for DENV proved this approach to be successful, after which another twenty-four molecules were produced to further explore and optimize the potency of this novel class of hybrid inhibitors. In the end, a molecule was obtained with an EC50 against dengue virus serotype 2 in the low micromolar range (23, 1.32±0.41μM).
